Rectus sheath hematoma: review of 126 cases at a single institution

Rectus sheath hematoma (RSH) is an uncommon condition characterized by abdominal pain and an abdominal wall mass. We reviewed the clinical features, treatment, and outcomes of 126 patients treated for RSH at Mayo Clinic from January 1, 1992, to December 31, 2002. Most patients (64%) were women and the mean +/- SD age was 67.9 +/- 16.5 years. Most patients (69%) were on some form of anticoagulation therapy. The mean international normalized ratio was 2.6 +/- 2.4, and mean activated partial thromboplastin time was 64.2 +/- 42.7 seconds. No patients were pregnant or had a peritoneal dialysis catheter at the time of diagnosis. Approximately half of the patients (48%) had nonsurgical abdominal trauma around the time of diagnosis, with 37 patients (29%) having a cough. The most common presenting signs and symptoms were abdominal pain (84%) and an abdominal wall mass (63%). CT of the abdomen and pelvis was the most commonly used method to establish the diagnosis (83%). Most patients (86%) were successfully treated with symptom management and blood transfusion. Ten patients (7.9%) underwent surgery or endovascular embolization of bleeding vessels, and 2 patients (1.6%) died as a result of RSH bleeding. Although RSH is rarely fatal, the clinician should be aware of important risk factors that lead to RSH including female sex, older age, anticoagulation therapy, and cough or other abdominal trauma. Rapid diagnosis with directed history, physical examination, and CT of the abdomen and pelvis may help decrease unnecessary laparotomy and lead to better triage of patients who present with RSH.     

Pancreatic phlegmon

The clinical course of 19 patients with pancreatic phlegmon, as diagnosed by computed tomography (CT) and clinical criteria, was assessed retrospectively and compared to that of eight patients with pancreatic abscess diagnosed either at surgery or with percutaneous aspiration. Controls consisted of 55 patients with uncomplicated acute pancreatitis without CT scans and 11 patients with acute pancreatitis in whom CT scans were negative or only consistent with acute pancreatitis (no phlegmon). The age, sex, and presumed etiology of the pancreatitis were not significantly different in the four groups. Patients with phlegmon had a higher incidence of severe pancreatitis as defined by Ranson's criteria, presence of an abdominal mass, as well as a longer duration of fever, abdominal pain and leukocytosis than controls without CT scans. With the exception of a palpable abdominal mass and fever lasting over five days, the results were similar when comparing the phlegmon group and controls with CT scans, although the severity of the disease and prolonged abdominal pain tended to be increased in the former patients. There was no statistically significant difference in clinical or laboratory criteria between the phlegmon and abscess groups, although the latter group had longer hospital stays and periods with no oral intake (npo). Management of patients with phlegmon tended to include TPN, longer npo periods, antibiotics, and longer hospital stay than in controls without CT scans. Controls with CT scans were managed similarly to the phlegmon group because of prolonged amylase elevation and abdominal pain, Percutaneous aspiration was successful in differentiating abscess from phlegmon in five of six cases. Major complications were rare in the phlegmon group and spontaneous resolution was the rule. Pancreatic phlegmon is a distinct clinical/radiologic entity which may be very difficult to differentiate clinically from pancreatic abscess. Early percutaneous thin-needle aspiration of the inflammatory mass (under CT guidance) seems to be the diagnostic procedure of choice. Management is nonsurgical unless complications arise. The role of TPN and antibiotics is unknown, and controlled studies of these therapeutic approaches in pancreatic phlegmon are needed.

Abstract：

Objective To investigate the etiology, clinical features, diagnosis and treatment of regional portal hypertension (RPH).Methods The clinical data of 26 patients with RPH treated in Beijing Chaoyang Hospital Affiliated to Capital Medical University between January 2005 and June 2010 were analyzed with retrospective analysis.The first symptom, routine analysis of blood, liver function test, hepatitis B and C markers, tumor markers, abdominal ultrasound, abdominal enhanced CT, endoscopy findings of 26 patients and the results of abdominal CT angiography (CTA) of 16cases were analyzed.Results Pancreatic disease (18 cases) was the leading cause of RPH.The main clinical manifestations of splenomegaly in 26 cases, irregularly abdominal pain in 14 cases, and upper gastrointestinal bleeding in 10 cases.Isolated gastric varices were revealed by endoscopy in 25 cases,complicated with lower esophageal varices in 1 case.4 cases with endoscopic tissue glue injection in gastric variceal bleeding, splenectomy in 4 cases, 2 cases with splenectomy and pericardialdevascularization, 2 cases with splenectomy, pancreatic tail resection and spleno-renal shunt, 3 cases with splenic embolization treatment.Conclusions RPH often accompanied by pancreatic disease,manifested as splenomegaly, hypersplenism, but normal liver function, absence of liver cirrhosis.Isolated gastric varices is the characteristic features of RPH.RPH caused by benign diseases is curable.Splenectomy is more effective than simple endoscopic hemostasis in RPH associated with gastrointestinal bleeding.     

Intraperitoneal metastasis of hepatocellular carcinoma after spontaneous rupture： A case report

Rupture of hepatocellular carcinoma （HCC） is a lifethreatening complication. Peritoneal metastasis of HCC after spontaneous rupture was seldom noted. We report a case of intraperitoneal metastasis of HCC after spontaneous rupture. A previously asymptomatic 72-yearold man was admitted due to dull abdominal pain with abdominal fullness. He had a history of HCC rupture 10 mo ago and transarterial embolization was performed at that time. Abdominal computer tomograghy （CT） scan showed a huge peritoneal mass over the right upper quadrant area. Surgical resection was arranged and subsequent microscopic examination confirmed a diagnosis of moderately-differentiated HCC.     

Difficult Preoperative Diagnosis of a Patient with Scierosing Splenic Hemangioma

We present a young asymptomatic woman with splenomegaly and a large isolated splenic mass demonstrated by ultrasonography, 99mTc sulfur colloid, and gallium scintigraphy studies. Computerized tomography (CT) and three-phase 99mTc-labeled red blood cell imaging suggested a malignant lesion. Repeated sonographically guided fine needle aspiration (FNA) obtained only blood, suggesting the possible vascular nature of the tumor. Splenectomy established the diagnosis of splenic hemangioma (SH) with marked sclerotic changes. We conclude from this case that 1) the sclerotic and cystic changes in the SH and the abdominal lymphadenopathy could explain why the three-phase red blood cell and CT scanning, respectively, suggested that the lesion was malignant rather than benign; 2) guided FNA of a splenic mass suspected to be hemangioma may be an additional safe and useful diagnostic procedure. Multiple aspirations yielding blood alone suggest hemangioma and may prevent an unnecessary operation. To the best of our knowledge, this is the first reported case in the literature of FNA of splenic hemangioma.     

Abdominal Kaposiform Hemangioendothelioma Associated With Lymphangiomatosis Involving Mesentery and Ileum: A Case Report of MRI,CT, and 18F-FDG PET/CT Findings

Kaposiform hemangioendothelioma (KH) is a rare vascular tumor of intermediate malignancy that occurs mainly in the childhood. Adult patients with KH are rare. Imaging findings of KH have rarely been reported before. We present magnetic resonance imaging (MRI), computed tomography (CT), and fluorine-18-fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography (PET)/CT findings in an adult patient with KH associated with lymphangiomatosis involving mesentery and ileum.A 22-year-old female complained of a 9-month history of intermittent melena, weakness, and palpitation. Laboratory tests revealed anemia and hypoproteinemia. Fecal occult blood test was positive. Abdominal enhanced MRI and CT showed a large abdominal mass involving mesentery and ileum. On enhanced MRI, there were many hypervascular nodules in the mass. On FDG PET/CT, the mass and the nodules showed slight FDG uptake. Small bowel capsule endoscopy showed numerous grape-shaped red nodules in the luminal wall of the involved ileum. The patient underwent resection of the abdominal mass and a segment of the ileum invaded by the abdominal mass. KH arising within lymphangiomatosis involving mesentery and ileum was confirmed by pathology. After surgery, the patient''s symptoms improved.This is the first case of KH associated with lymphangiomatosis involving mesentery and ileum. In this case, the lymphangiomatosis overshadowed the small tumor nodules resulting in unusual imaging findings. Familiarity with these imaging findings is helpful for diagnosis and differential diagnosis of KH.     

Body composition analysis using abdominal scans from routine clinical care in patients with Crohn’s Disease

Objective: Crohn’s Disease is associated with body composition changes, which have important treatment and prognostic implications. Measurement of body composition usually requires dedicated scanning or measurement, with retrospective analysis of existing datasets impossible. We sought to determine whether single slice analysis of abdominal scans, obtained during routine clinical care, in patients with Crohn’s Disease accurately predicts body composition compartments.

Materials and methods: Abdominal CT images of patients with Crohn’s disease were analyzed and comparison was made with total body fat-free mass, total body fat mass, femoral neck t-score, and other parameters reported from DXA, the reference method.

Results: Thirty-seven subjects were identified, 15 male and 22 female, with a mean age of 43.8 years. There was significant correlation (Pearson r?=?0.923, p?r?=?0.928, p?Conclusions: Fat mass, fat-free mass, and appendicular skeletal muscle index can be predicted by analysis of a single CT slice in patients with Crohn’s Disease. Similar to published data from healthy subjects, the L3 vertebral body level provided the most robust correlation with most parameters. This study represents the first published use of routinely obtained abdominal imaging to demonstrate this relationship – and to predict body composition components – in patients with inflammatory bowel disease.     

Perforated duodenal diverticulum successfully diagnosed preoperatively with abdominal CT scan associated with upper gastrointestinal series

Although duodenal diverticulum is not uncommon, precise preoperative diagnosis is occasionally difficult. We report a patient with perforated duodenal diverticulum successfully diagnosed preoperatively by an upper gastrointestinal series followed by abdominal computed tomography (CT) scanning. An 81-year-old Japanese woman visited a local hospital because of right-sided abdominal pain. Physical examination revealed diffuse muscle guarding localized in the entire right-side of the abdomen indicative of peritonitis. While plain abdominal X-ray film revealed no free air, abdominal ultrasound and abdominal CT scanning revealed fluid collection and gas in the anterior perirenal space. An emergency upper gastrointestinal series, using water-soluble contrast media, demonstrated multiple diverticula in the descending portion and the horizontal portion of the duodenum. Leakage of the contrast material was found by the upper gastrointestinal series followed by the abdominal CT scanning, suggesting that the peritonitis was caused by the perforated duodenal diverticulum, and an emergency laparotomy was performed. The diverticulum in the descending portion of the duodenum was mobilized from the retroperitoneum and complete resection and peritoneal drainage were performed. The resected specimen showed that the diverticulum was 42 × 23mm in size, and two separate sites of perforation were identified. The present case suggests that upper gastrointestinal series followed by CT scan is useful for the preoperative diagnosis of perforated duodenal diverticulum.     

Abdominal computed tomography findings of malaria infection with Plasmodium vivax

Abdominal computed tomography (CT) findings of malaria are not well-known even though malaria is a serious infectious disease. To identify abdominal CT findings, we selected 34 of 405 patients who had a positive peripheral blood smear for Plasmodium vivax and had underwent abdominal CT as the malaria group. We also selected 80 patients who had fever and a negative peripheral blood smear as the control group and 120 healthy people as the normal group. We reviewed and analyzed their medical records and CT findings retrospectively. The mean spleen and liver length were significantly larger in the malaria group and the incidence of splenomegaly, splenic focal low attenuation, and spontaneous splenic rupture were much higher in the malaria group (P < 0.05). Although abdominal CT is not an indispensable tool for diagnosis, these CT findings will help in the diagnosis of malaria in patients with fever.     

Immunoglobulin G4-related hepatic inflammatory pseudotumor invading the abdominal wall

A 50-year-old woman presented with epigastralgia. Computed tomography (CT) of the abdomen revealed a 6-cm well-enhanced mass extending from the left lobe of the liver to the abdominal wall, suggestive of cholangiocarcinoma. Liver and skin mass biopsies did not provide evidence of hepatic malignancy but were rich in plasma cells and sclerotic lesions. Subsequent detection of elevated serum immunoglobulin G4 (IgG4) led to a diagnosis IgG4-related inflammatory pseudotumor (IPT) of the liver. Treatment with systemic corticosteroids resulted in rapid clinical improvement. This case is the first report of an IgG4-related hepatic IPT invading the abdominal wall.     

Mesenteric venous thrombosis: early diagnosis with abdominal CT scan and screening for coagulopathies. Six observations

PURPOSE: Mesenteric venous thrombosis is an uncommon entity whose diagnosis is difficult because the symptoms are nonspecific. Yet early recognition of this disease helps avoid the evolution towards mesenteric infarction. METHODS: We describe clinical symptoms and hypercoagulable states discovered in six patients with superior mesenteric venous thrombosis. RESULTS: Five of six patients were admitted to hospital for abdominal pain whose mean duration was 9 days before the diagnosis of venous thrombosis was made. Three of them had a fever. Two patients had a past history of deep venous thrombosis. All patients had a hypercoagulable state and three of them had two associated disorders of coagulation. In all cases, abdominal CT scan had permitted the diagnosis of mesenteric venous thrombosis. An anticoagulant therapy was conducted successfully in five of six patients. CONCLUSION: A CT abdominal scan done early in the case of nonspecific abdominal pain, since the patients had a previous history of venous thrombosis, may permit a nonsurgical treatment of mesenteric venous thrombosis. A screening for thrombophilia must always be carried out since coagulation disorders are very frequently the recognised causes in mesenteric venous thrombosis.     

Spontaneous intramural esophageal hematoma. Diagnosis by CT scanning

We describe a patient who suffered a spontaneous intramural esophageal hematoma while taking aspirin and dipyridamole. The diagnosis was initially made at endoscopy, with confirmation by computed tomography (CT). CT scanning was particularly valuable in both the diagnosis and in the follow-up of this lesion. As the prognosis for a spontaneous intramural esophageal hematoma is good with conservative management, its specific definition by computed tomography should facilitate proper management decisions.     

Exophytic inflammatory myofibroblastic tumor of the stomach in an adult woman： A rare cause of hemoperitoneum

Inflammatory myofibroblastic tumor （INT） of the stomach in adults is extremely rare, with unpredictable prognosis. We present a 55-year-old woman with a gastric IMT. She experienced sudden abdominal pain 4 d previously. Physical examination showed mild abdominal tenderness in the hypogastrium, but no palpable abnormal abdominal mass. Abdominal CT showed a mass of approximately 8 cm in the gastrocolic ligament. On laparoscopic exploration, unexpected hemoperitoneum of approximately 1.5 L of blood was found, and an exophytic gastric mass of approximately 10 cm, appeared from the anterior wall of the gastric body along the greater curvature. Laparoscopy further showed that non- clotting blood in the abdominal cavity seemed to be from the gastric tumor. After conversion to open surgery for more precise evaluation of the cause of hemoperitoneum and the large friable tumor, gastric wedge resection, including the tumor, was conducted. The final diagnosis was consistent with IMT that originated from the gastric wall.     

Retained foreign bodies following intra-abdominal surgery.

BACKGROUND/AIMS: A retained foreign body in the abdominal cavity following surgery is a continuing problem. Despite precautions, the incidence is grossly underestimated. The purpose of this study is to report the result of surgical treatment on 24 consecutive cases treated by the authors during a 10-year period. METHODOLOGY: All consecutive patients with a confirmed diagnosis of foreign body after abdominal surgery were studied. Data collected included the patients' age and sex, the initial diagnosis and primary surgical treatment, period of time between the probable causative operation and the definitive treatment, nature of the foreign body, clinical presentation, predisposing factors, and diagnosis and management; morbidity and mortality are presented as well as guidelines for prevention. RESULTS: All patients were symptomatic. Eight patients presented as intraabdominal sepsis (4 with intestinal obstruction, 4 with entero- or colo-cutaneous fistula), non-specified abdominal pain in 3, persistent sinus and granuloma in 2, abdominal palpable mass in another 2 cases, and 1 patient with vaginal discharge. The diagnosis was established pre-operatively in 15 cases by means of plain abdominal radiographs, ultrasound or computed tomography (CT) scan. Morbidity was observed in 50% and the rate of surgical reinterventions because of fistulas or residual sepsis in 18%. The mortality was almost 10%. CONCLUSIONS: The clinical manifestations ranged from mild abdominal pain, palpable mass, persistent drainage and granuloma to intestinal obstruction secondary to adhesions or occlusion of the intestinal lumen because of migration of the foreign body and intraabdominal sepsis. Despite this being a rare situation, when it happens it presents as a very serious problem to patients with high rates of morbidity and mortality. Prevention remains the key to the problem.     

Body composition and metabolic factors in obese children and adolescents

OBJECTIVE: Body composition is associated with metablic factors in adults; however, data are limited regarding obese children. This study was undertaken to assess body composition, regional fat distribution, and metabolic factors in obese 6-18-y-old children and adolescents. DESIGN: Cross-sectional assessment. SUBJECTS: Thirty-six obese children and adolescents, (mean+/-s.e.m.) age 11.8+/-0.5 y, BMI 34.1+/-1.2 kg/m(2). MEASUREMENTS: Body composition was assessed by dual energy X-ray absorptiometry and computerized tomography. Fasting insulin, glucose and leptin levels, and the homeostasis model assessment of insulin sensitivity (HOMA-IR) were assessed. RESULTS: The girls had significantly lower glucose levels than the boys. The ethnic group differences (African American children vs white children) in fat mass, total CT fat, subcutaneous CT fat, insulin level, leptin level, and higher HOMA-IR were not significant after adjusting for age or pubertal stage. These differences in abdominal fat and subcutaneous abdominal fat were also not independent of total body fat or BMI. No ethnic group differences in visceral abdominal fat were noted. Insulin level and HOMA IR were associated with leptin level (independent of fat mass) and fat mass. Leptin level was associated with fat mass, total CT fat, and subcutaneous CT fat; however the associations between the CT fat measures and leptin were not independent of total body fat mass. CONCLUSIONS: Neither visceral abdominal fat, subcutaneous abdominal fat, insulin levels, or insulin resistance differed by ethnic group when adjusted for age or pubertal status. This contrasts with findings in adults and non-obese children which suggest lower levels of visceral fat and higher insulin levels and insulin resistance in African American children and adolescents.     

Spinal destruction caused by chronic contained rupture of an infra-renal abdominal aortic aneurysm

The erosion of the lumbar vertebral bodies by a chronic contained rupture of an infra-renal abdominal aortic aneurysm is a rare event. Chronic contained rupture can cause diagnostic difficulties as there are many clinical presentations, such as: back pain, sciatic pain or an expansive abdominal mass. The diagnosis is sometimes made following an incidental finding on radiological examination. Currently a CT scan is the gold standard diagnostic tool. The outcome following urgent surgical or endovascular repair is equivalent to that of an elective aneurysm repair. We report a case of a 59 year old man admitted for septic rupture of a cutaneous fistula resulting from a false aneurysm in the left groin. Pre-operative CT scan revealed a 6 cm abdominal aortic aneurysm, with chronic contained rupture. This had caused bone erosion of the vertebral body of the third lumbar vertebrae.     

Inflammatory myofibroblastic tumor successfully treated with chemotherapy and nonsteroidals: A case report

Inflammatory myofibroblastic tumor (IMT) occurring at retroperitoneal sites has rarely been reported. We report the case of a previously well 14-year-old girl with no history of abdominal disease whose past medical history and family tumor history were unremarkable. She complained of intermittent abdominal pain for one month. An abdominal mass was found on physical examination and abdominal contrast-enhanced computed tomography (CT) showed a hypodense soft mass, the size and location of which suggested a well delineated retroperitoneal tumor surrounding the superior mesenteric vessels measuring 3.3 cm × 4.5 cm × 4.5 cm with enlarged lymph nodes. The patient underwent an exploratory laparotomy followed by biopsy and was subsequently diagnosed with retroperitoneal IMT. She was successfully treated with postoperative chemotherapy and oral diclofenac sodium. Following completion of therapy the mass was no longer palpable and no longer visible on CT scanning. The use of methotrexate and cisplatin for aggressive myofibroblastic tumors is also reviewed.     

Pancreatic pseudotumor due to peripancreatic tuberculous lymphadenitis

Peripancreatic tuberculous lymphadenitis is a very rare and difficult diagnosis. We report herein a patient with a clinically solitary abdominal tuberculoma. A 68-year-old woman was admitted to our hospital with moderate-level obstructive jaundice due to a mass located between pylorus and head of the pancreas. There were no clinical signs or symptoms of tuberculosis in lungs or abdomen. After the diagnosis of a neoplasm of the pancreas was made, exploratory laparotomy was performed which revealed a conglomerated mass penetrating into the pancreas. Since an exact diagnosis could not be reached on the basis of frozen sections prepared during the operation, a standard Whipple procedure was performed. After the histopathological examination of the resected specimen revealed tuberculous lympadenitis, the patient was given antituberculous medication. The patient recovered well. An abdominal tuberculoma is often mistaken for a malignant neoplasm, and nonsurgical diagnosis and treatment of this entity continues to be a challenge.     

胸部低剂量CT扫描在AIDS合并PCP体质量低者中的应用价值

目的探讨低剂量CT扫描在AIDS合并PCP体质量低者中的应用可行性及临床价值。方法将69例AIDS合并PCP体质量低患者,随机分成3组,分别采用管电压固定为120kV,常规剂量(自动mAs)与低剂量扫描,低剂量扫描管电流分别采用40mAs,30mAs,20mAs,对图像质量、辐射剂量进行分析,得出AIDS合并PCP体质量低患者的最优低剂量扫描方案。结果常规剂量扫描与低剂量扫描获得图像均能达到影像诊断要求。采用管电压固定为120kV,管电流为常规剂量、40 mAs、30 mAs、20 mAs组获得的平均辐射剂量CTDIvol分别为:6.65mGy、2.06 mGy、1.54 mGy、1.03 mGy,管电流20 mAs组最低,为常规剂量的15.5%。结论采用管电压kV值固定为120kV,管电流20mAs胸部低剂量CT扫描在AIDS合并PCP体质量低患者中图像质量能满足临床诊断要求,同时降低辐射剂量,值得推广。     

Clinical significance of mesenteric panniculitis-like abnormalities on abdominal computerized tomography in patients with malignant neoplasms

AIM To clarify the association of malignancy with mesenteric panniculitis-like changes on computed tomography(CT).METHODS All abdominal CT scans performed at North Shore University HealthS ystem showing mesenteric panniculitis from January 2005 to August 2010 were identified in the Radnet(Rad Net Corporation, Los Angeles, CA) database. Patients with a new or known diagnosis of a malignancy were included for this analysis. Longitudinal clinical histories were obtained from electronic medical records.RESULTS In total, 147794 abdominal CT scans were performed during the study period. Three hundred and fiftynine patients had mesenteric panniculitis(MP)-like abnormalities on their abdominal CT. Of these patients, 81 patients(22.6%) had a known history of cancer at the time of their CT scan. Nineteen(5.3%) had a new diagnosis of cancer in concurrence with their CT, but the majority of these(14/19, 74%) were undergoing CT as part of a malignancy evaluation. Lymphomas were the most common cancers associated with MPlike findings on CT(36 cases, 36%), with follicular lymphoma being the most frequent subtype(17/36). A variety of solid tumors, most commonly prostate(7) and renal cell cancers(6) also were seen. CT follow up was obtained in 56 patients. Findings in the mesentery were unchanged in 45(80%), worsened in 6(11%), and improved in 5 patients(9%). Positron emission tomography(PET) scans performed in 44 patients only showed a positive uptake in the mesenteric mass in 2 patients(5%). CONCLUSION A new diagnosis of cancer is uncommon in patients with CT findings suggestive of MP. MP-like mesenteric abnormalities on CT generally remain stable in patients with associated malignancies. PET scanning is not recommended in the evaluation of patients with mesenteric panniculitis-like findings on CT.
