Intraosseous ganglion cyst of the humeral head in a competitive flat water paddler: case report

Objective

To present the diagnostic and clinical features of an intraosseous ganglion cyst of the humeral head of a female flat water canoe athlete.

Clinical Features

An 18-year old female flat water canoeist complaining of right shoulder pain following a strenuous paddling training camp.

Intervention and outcome

A trial of passive care was conducted, including soft tissue therapy, spinal manipulative therapy, acupuncture, and rehabilitation. The patient seemed to be responding with treatment, but pain would always resume with paddling. A diagnostic ultrasound displayed mild thickening and effusion in the subacromial/subdeltoid bursae. Continued passive care was not able to resolve the symptoms and she underwent an MRI which revealed an intraosseus ganglion cyst subjacent to the lesser tuberosity and floor of the intertubercular groove. A subsequent MRA was ordered to assess the labrum, which was intact, but the cyst had progressed in size. She was referred to an orthopedic surgeon who performed surgery.

Conclusion

An IOG cyst within the humeral head is a rare, potentially painful condition that can mimic other pathologies including impingement and labral tear. It is important to be aware of the clinical features to obtain a prompt diagnosis and appropriate treatment of this condition.     

Ganglion cyst of the cruciate ligament with atlantoaxial subluxation

Background

Ganglion cysts of the cruciate ligament are rare and sometimes asymptomatic. The authors present three cases of ganglion cysts of the cruciate ligament with atlantoaxial subluxation, which has rarely been reported previously.

Methods

Generally, ganglion cysts of the cruciate ligament are reported as case reports. Several theories regarding the process of cyst formation and the development of treatment options have been described. However, trans-oral decompression with total removal of the cyst may be one of the options for treatment of this kind of disease.

Results

A retrospective review of three patients, two female and one male patient, with a mean age of 68 years was conducted. The operation performed was a trans-oral decompression with cyst removal for all patients. Clinical outcomes were evaluated after the operation. All patients underwent trans-oral decompression with total removal of the cyst, followed by posterior fusion and pathologic examination of the cyst, revealing myxoid stroma with an absence of synovial linings.

Conclusion

The ganglion cysts and synovial cysts of the cruciate ligament are two different diseases with different presentation, pathogenesis, pathophysiology, and pathologic findings.     

Ganglion cyst of the foot treated with electroacupuncture: A case report

Objective:

To present the clinical management of a ganglion cyst presenting on the dorsolateral aspect of the foot.

Clinical Features:

A 45-year-old female cyclist complaining of ganglion cyst following training period.

Intervention and Outcome:

Patient was treated with high-frequency electroacupuncture in four consecutive sessions over four weeks, and reported resolution of the cyst following therapeutic intervention.

Conclusions:

Ganglion cysts of the foot are relatively rare connective tissue tumours with variable treatment approaches. Electroacupuncture may be a novel and non-invasive conservative approach for the treatment of ganglion cysts. Further evaluation of the efficacy of such treatment is warranted.     

Giant chylolymphatic mesenteric cyst and its successful enucleation: A case report

INTRODUCTION

Cysts of the mesentery are among surgical rarities. The clinical presentation is not characteristic and in addition, the preoperative imaging although suggestive is not diagnostic in this case ultrasound and CTscan was consistent with giant mesenteric cyst. In most cases, the diagnosis is confirmed after surgical exploration.

PRESENTATION OF CASE

A 42 yrs old male patient on exploratory laparotomy had a 14cm×10cm×10 cm cysts which was seen arising from the mesentery ofdistal jejunum 80cm from the duodeno jejunal flexure. The cyst was enucleated successfully from themesentery without entailing resection. The cyst contained milky white fluid consistent with a chylolymphatic cyst. The diagnosis was confirmed on histopathology which revealed a cyst wall with lymphoidaggregates. After 3 years of follow-up, the patient is doing well and there is no evidence of recurrence.

DISCUSSION

The cysts may be asymptomatic or maymanifest with abdominal pain, distension lump or intestinal obstruction. Our patient was symptomatic with mild and long standing abdominal pain. The definitive diagnosis of these lesions is difficult prior to surgical exploration as there are no pathognomonic symptoms or characteristic imaging findings.

CONCLUSION

Cysts of the mesentery are among surgical rarities. In most of the cases the diagnosis is confirmed after surgical exploration and removal of thecyst. We would like to emphasize the importance of successful enucleation of the cyst irrespective of its size due to its independent blood supply as opposed to enterogenous cyst which requires bowel resection and anastomosis.     

A giant adrenal cyst difficult to diagnose except by surgery

Introduction

Adrenal cysts represent rare clinical entities. Although surgical indications are well defined, pitfalls arise from the failure to establish an accurate preoperative diagnosis. Cystic lesions of other abdominal organs especially the pancreas complicate the diagnostic field.

Presentation of case

We present the case of a giant adrenal cyst in a young female causing diagnostic dilemma. Imaging studies revealed a large cystic lesion of uncertain origin located between the spleen and the tail of the pancreas. It was decided to perform a laparotomy which confirmed the presence of an adrenal cyst and enucleation of the cyst was performed. Examination at one year confirmed no complications.

Discussion

Adrenal cysts should always be included in the differential diagnosis of cystic abdominal lesions.

Conclusion

When the preoperative diagnosis is uncertain, surgical intervention can be both diagnostic and therapeutic.     

Paraduodenal herniation: An internal herniation in a virgin abdomen

INTRODUCTION

A paraduodenal hernia is an uncommon hernia that results from an abnormal rotation of the midgut. Commonly, these hernias are congenital in nature, and are reported to cause 1.5–5.8% of intestinal obstructions. These hernias occur when a part of the jejunum herniates through the posterior portion of the ligament of Treitz. Diagnosing these hernias preoperatively has been shown to be difficult, despite the studies that are available. Early diagnosis is imperative to the patient in order to avoid strangulation of the bowel, which is associated with a high mortality.

PRESENTATION OF CASE

In this case, we present a case of a left-sided paraduodenal hernia in a virgin abdomen in a 38-year-old African American male with a herniation of a loop of jejunum through a defect of the posterior portion of the ligament of Treitz. The patient also had a volvulized segment of the proximal jejunum, and part of this bowel was found to be ischemic.

DISCUSSION

Acute intestinal obstruction caused by a left paraduodenal hernia is a rare cause of intestinal obstruction. A literary search of PubMed between 1980 and 2012 indicated only 44 cases of intestinal obstruction secondary to a left paraduodenal hernia.

CONCLUSION

The patient underwent exploratory laparotomy, and the herniated bowel was found to be ischemic. The hernia was reduced, and the ischemic bowel resected. The defect was closed, and the patient had a non-complicated recovery.     

Ganglion cyst in children: Reviewing treatment and recurrence rates

BACKGROUND:

Pediatric hand and wrist ganglia seem to have different epidemiological characteristics than those of adults – a majority are found on the volar aspect of the hands and wrists of patients younger than 10 years of age.

OBJECTIVE:

To determine the epidemiology, etiological factors, clinical presentation, treatment and outcome of patients with ganglion cysts at The Hospital for Sick Children (Toronto, Ontario).

METHODS:

The records of the pathology department at The Hospital for Sick Children were searched for all cases of ganglion cyst operated on between January 2000 and December 2008.

RESULTS:

Thirty-seven patients underwent treatment for symptomatic ganglion cyst. The mean age of the patients was 9.6 years, and there were 23 females. A mobile nodule was the initial presentation of the ganglion in 64% of the cases. Pain was the most common indication for surgical removal. Only 11.4% of patients experienced previous trauma. In 70% of the cases, the diagnosis was made clinically. The most common sites of occurrence were volar wrist (25.7%), dorsal wrist (22.8%) and the volar aspect of the base of the ring finger (17.1%). Surgical excision was the treatment of choice for 94.2% of the patients with symptomatic lesions. The minimum follow-up period was 12 months. Only one patient (2.8%) presented with recurrence in the series.

CONCLUSION:

Although it is possible that these findings might change with longer follow-up, the present data provide information to help guide the treatment of these cysts. Complete surgical removal is a very effective treatment, with low rates of recurrence.     

Hepatobiliary rhabdomyosarcoma mimicking choledochal cyst: Lessons learned

INTRODUCTION

The differential diagnosis of hepatic cystic lesions is a challenging process especially in case of hepatic rhabdomyosarcoma (HRMS) presenting as hepatic cyst.

PRESENTATION OF CASE

We introduce our experience with a case of HRMS in a 3-year-old female patient who was misdiagnosed to have type IV-A choledochal cyst and definitive correct diagnosis was reached after the pathological and immunohistochemical examination of the surgically resected lesion. This case presentation is followed by important practical messages to hepatobiliary surgeons regarding HRMS.

DISCUSSION

HRMS is a rare pediatric tumor. Jaundice is the most common presentation of HRMS followed by abdominal pain and vomiting. Great effort is needed to differentiate the tumor from choledochal cyst and infectious hepatitis. Through evaluation using available imaging studies together with clinical anticipation is mandatory for establishing the correct diagnosis.

CONCLUSION

Differentiation of HRMs from choledochal cyst mandates through evaluation and clinical anticipation. HRMS should be suspected in any child with obstructive jaundice. Once diagnosis is established, multidisciplinary treatment is the best management strategy and it has proved better surgical outcome and long term survival.     

Thoracic Myelopathy Secondary to Intradural Extramedullary Bronchogenic Cyst

Background/Objective:

To report a case of thoracic myelopathy secondary to intradural extramedullary bronchogenic cyst.

Study Design:

Case report.

Methods/Findings:

A 20-year-old man presented to the emergency department with increasing back pain and lower-extremity weakness. Magnetic resonance imaging demonstrated a cystic lesion at the T4 level with mass effect on the spinal cord.

Results:

The lesion was resected, and histopathologic evaluation showed a cyst lined by respiratory-type epithelium consistent with a bronchogenic cyst.

Conclusions:

Intradural extramedullary bronchogenic cysts of the thoracic spine have been reported previously but are extremely rare. The treatment of choice is surgical resection.     

Primary hydatid cyst of pancreas with acute pancreatitis

Context

Primary hydatid disease of the pancreas is very rare and even rarer to cause pancreatitis.

Case report

We report the case of a 20-year-old man who presented with abdominal pain and an epigastric mass. A diagnosis of a pancreatic hydatid cyst was established by ultrasonography and CT scan before surgery. The treatment consisted of laparoscopic cyst evacuation with omentoplasty. The recovery was uneventful and the patient has remained symptom free so far.

Conclusions

Hydatid disease should be considered in the differential diagnosis of all cystic masses in the pancreas, especially in the geographical regions where the disease is endemic.Keyword: Primary hydatid cyst of pancreas     

Diagnosis and rehabilitation of gastrocnemius muscle tear: a case report

Objective:

This case study presents the epidemiology, etiology, diagnostic criteria, and therapeutic interventions for a common clinical condition – gastrocnemius injury.

Clinical Features:

A 44-year old male presented with acute calf pain with a palpable defect, loss of range of motion, and loss of strength after sustaining a soft tissue injury to the lower leg. The differential diagnosis of tear of the medial head of the gastrocnemius was confirmed by physical examination and diagnostic ultrasound imaging.

Intervention and Outcome:

The patient was treated over a 6 week period. Initially, rehabilitation was approached using the PRICE principles for symptomatic relief, followed by stretching, strengthening, proprioception, and conditioning exercises. At 9-month follow-up post injury, there was no residual impairment in the gastrocnemius muscle function.

Summary:

This case demonstrates the importance of epidemiology, clinical assessment, and the use of diagnostic ultrasound and MRI imaging in the diagnosis of a tear of the medial head of the gastrocnemius muscle. With an accurate diagnosis and comprehension of classification of muscle injuries, management of gastrocnemius tears is straightforward.

Prediction of Chronicity of Anterior Cruciate Ligament Tear Using MRI Findings

Background

The estimation of anterior cruciate ligament (ACL) tear is required in certain cases involving legal and financial administration, such as the worker''s compensation and/or insurance. The aim of this study is to propose and evaluate a quantitative evaluation instrument to estimate the chronicity of the ACL tear, based on the four magnetic resonance imaging (MRI) findings.

Methods

One hundred and fifty one cases of complete ACL tear confirmed by arthroscopy were divided into 4 groups according to the time from ACL injury to MRI acquisition: acute (< 6 weeks), subacute (6 weeks to 3 months), intermediate (3 months to 1 year), and chronic (> 1 year). The four MRI findings including ACL morphology, joint effusion, posterior cruciate ligament angle, and bone bruise were analyzed for temporal changes among the 4 groups. Binary logistic regression equations were formulated using the MRI findings to estimate the chronicity of ACL tear in a quantitative manner, and the accuracy of the formulated regression equations was evaluated.

Results

The four MRI findings showed substantial temporal correlation with the time-limits of ACL injury to be included in the estimation model. Three predictive binary logistic equations estimated the probability of the ACL injury for the three cutoff time-limits of 6 weeks, 3 months, and 1 year with accuracies of 82.1%, 89.4%, and 89.4%, respectively.

Conclusions

A series of predictive logistic equations were formulated to estimate the chronicity of ACL tear using 4 MRI findings with chronological significance.     

Diagnostic and therapeutic value of laparoscopy for small bowel blunt injuries: A case report

INTRODUCTION

Small bowel injuries after blunt abdominal trauma represent both a diagnostic and a therapeutic challenge. Early diagnosis and prompt treatment are necessary in order to avoid a dangerous diagnostic delay. Laparoscopy can represent a diagnostic and therapeutic tool in patients with uncertain clinical symptoms.

PRESENTATION OF THE CASE

We report the case of a 25-year-old man, haemodynamically stable, admitted for acute abdominal pain a few hours after a physical assault. Giving the persistence of the abdominal pain and the presence of free fluids at the computed tomography examination, an exploratory laparoscopy was performed.

DISCUSSION

At the laparoscopic exploration, an isolated small bowel perforation was found, 60 cm distal from the ligament of Treitz. The injury was repaired by laparoscopic suturing and the patient was discharged home at postoperative day 3 after an uneventful postoperative course.

CONCLUSIONS

Laparoscopy represents a valuable tool for patients with small bowel blunt injuries allowing a timely diagnosis and a prompt treatment.     

Oversized pseudocysts of the spleen: Report of two cases: Optimal management of oversized pseudocysts of the spleen

INTRODUCTION

Pseudocysts of the spleen are usually asymptomatic and associated with a history of trauma, infection or infarction. In this report, we present two uncommon cases of solitary, oversized pseudocysts of the spleen.

PRESENTATION OF CASE

Two patients (cases A and B), with symptoms of abdominal pain, were investigated. The laboratory and ultrasound examination confirmed the diagnosis of a large, non-parasitic splenic cyst in both cases. Computed tomography described an oversized pseudocyst occupying almost the entire splenic parenchyma in both cases and in patient A, the cyst was located in the splenic hilum. The medical history revealed a previous abdominal injury only in case A. The two patients underwent an open total splenectomy. The pathology examination verified the diagnosis of a non-parasitic splenic pseudocyst.

DISCUSSION

Both patients presented with symptoms, in contrast to the majority of patients with splenic cysts. The medical history of patients with splenic pseudocysts does not always reveal the cause of the pseudocyst formation. Any type of spleen-sparing procedure is not easy to perform in cases of surgical and anatomical difficulty, because of recurrence and the risk of intractable bleeding from the spleen.

CONCLUSION

Partial splenectomy is the recommended method for parenchymal preservation, but total splenectomy is preferred when the splenic cyst is oversized or cannot be excised with safety.     

Intractable Pruritus After Traumatic Spinal Cord Injury

Background:

This report describes a young woman with incomplete traumatic cervical spinal cord injury and intractable pruritus involving her dorsal forearm.

Method:

Case report.

Findings:

Anatomic distribution of the pruritus corresponded to the dermatomal distribution of her level of spinal cord injury and vertebral fusion. Symptoms were attributed to the spinal cord injury and possible cervical root injury. Pruritus was refractory to all treatments, including topical lidocaine, gabapentin, transcutaneous electrical nerve stimulation, intravenous Bier block, stellate ganglion block, and acupuncture.

Conclusions:

Further understanding of neuropathic pruritus is needed. Diagnostic workup of intractable pruritus should include advanced imaging to detect ongoing nerve root compression. If diagnostic studies suggest radiculopathy, epidural steroid injection should be considered. Because the autonomic nervous system may be involved in complex chronic pain or pruritic syndromes, sympatholysis via such techniques as stellate ganglion block might be effective.
