Isolated splenic vein thrombosis secondary to splenic metastasis： A case report

INTRODUCTIONIsolated splenic vein thrombosis is a rare clinical syndrome that may lead to left-sided portal hypertension.Metastasis to the spleen from solid tumors is also considered rare.When identified it usually occurs in the setting of widely dissemin…     

Isolated splenic tuberculosis: A case report

We present a rare case of a 36 year old man who presented with recurrent fever but no other symptoms. Laboratory data provided no specific information for diagnosis. Abdominal ultrasonography revealed splenomegaly with multiple small hypoechoic lesions within the spleen. Computed tomography of abdomen showed a hypodense diffuse lesion. A diagnosis of isolated splenic tuberculosis was confirmed after a splenic puncture and histopathological examination.     

Spleen infarct secondary to thrombus in COVID-19-related splenic vein: A case report

Splanchnic venous thrombosis is a rare type of venous thromboembolism, and its actual incidence is still unknown. Splenic infarction develops due to splenic vein (SV) thrombosis. Patients with COVID-19 may be exposed to a risk of thrombotic events, and the system affected at the highest level by coagulopathy is the respiratory system. The case presented here is splenic infarction that developed because of SV thrombosis, which is a rare form of venous thromboembolism.     

Left-sided pleural effusion secondary to splenic vein thrombosis. A previously unrecognized relationship

The association of left-sided pleural effusion and subcapsular splenic hematoma was reported in 1980. We describe a patient in whom a left-sided pleural effusion resulted from splenic vein thrombosis, a relationship not previously reported. Splenectomy was performed, demonstrating the spleen to be enlarged and hemorrhagic. The pleural effusion did not recur after splenectomy. The three effusions due to splenic hematomas reported previously cleared only after splenectomy, suggesting splenectomy may be necessary to prevent reaccumulation. We propose possible pathophysiologic mechanisms and recommend that splenic vein thrombosis be considered in the differential diagnosis of unexplained left-sided pleural effusions.     

Isolated splenic metastasis from colon cancer: Case report

Isolated splenic metastases from colorectal cancer are very rare clinical entities and when they are present, they usually manifest widely disseminated disease. In this paper we report a case of metachronous solitary isolated splenic metastasis from colon cancer in a 64-year-old woman who was successfully treated by laparoscopic splenectomy. We discuss the pathological and clinical aspects of this condition. We furthermore comment on the diagnostic and therapeutic options of this rare entity through our observation of the case and consideration of the 31 case reports published in the literature.

Renal vein thrombosis: a case report

The presenting symptoms of acute renal vein thrombosis (RVT) can often be confused with those of nephrolithiasis. Delayed diagnosis and treatment of RVT can result in catastrophic complications, including loss of renal function and pulmonary embolism. A high clinical suspicion and early imaging with computed tomography or magnetic resonance imaging will allow early initiation of therapy and prevention of thrombus extension in patients with RVT.     

Isolated splenic vein thrombosis with natural shunt caused by jejunal tuberculosis

A case of jejunal tuberculosis causing isolated splenic vein thrombosis with natural shunt is reported, for the first time. The patient, presented with upper small bowel obstruction and massive upper gastrointestinal bleeding, was treated successfully with splenectomy, jejunal resection and antituberculous drugs.     

Isolated splenic vein thrombosis: an unusual cause and review of the literature.

Isolated obstruction (mainly due to thrombosis) of the splenic vein usually results in left-sided portal hypertension and isolated fundal varice formation. This syndrome is a rare cause of gastrointestinal bleeding. Pancreatic diseases are among the most common etiologies of splenic vein obstruction. Renal disorders are rarely reported as a cause of splenic vein thrombosis. In the present article, a case of a 26-year-old woman with a perirenal abscess presenting with gastrointestinal bleeding as a complication of an isolated splenic vein thrombosis is described. The thrombosis could not be visualized with ultrasonography and angiography because of its extremely proximal localization. Fundal varices disappeared following splenectomy and nephrectomy. Follow-up at one year revealed the patient to be well both clinically and endoscopically.     

Lipoma causing upper extremity deep vein thrombosis: A case report

We report a case of lipoma in the right infraclavicular and axillary area compressing subclavian vein there by presenting with upper extremity deep venous thrombosis (UEDVT) and persistent symptoms of venous congestion. Patient was also found to be a heterozygous carrier of prothrombin 20210 gene mutation. Surgical excision of lipomatous tissue performed after 6 months of anticoagulation resulted in a complete resolution of symptoms.     

Isolated sigmoid varicose vein rupture and hemorrhage: A case report

Rationale:Ectopic varices are the collateral circulation of portal vein located anywhere in the gastrointestinal tract other than the esophageal and gastric regions. Rupture of these varices often results in life-threatening hemorrhage. Management guidelines for ectopic variceal bleeds are not yet standardized because cases are rare and treatment approaches described in the literature vary considerably.Patient concerns:A 53-year-old woman with a 20-year history of chronic hepatitis C cirrhosis came to our hospital for treatment due to intermittent black stools for 4 days. After admission, the patient developed hemorrhagic shock, with hemodynamic instability.Diagnosis:Postoperative histological examination confirmed the diagnosis of sigmoid varicose veins.Intervention:Emergency colonoscopy showed that a varicose vein mass in the sigmoid colon wall 30 cm from the anus was ruptured and bleeding. Percutaneous transhepatic inferior mesenteric venography revealed the presence of a varicose mass of sigmoid colon veins. After embolization of the sigmoid varicose veins with spring coils, angiography showed that the hemorheology of the distal varicose vein mass was slow but not completely blocked. Three days after embolization, the patient had hematochezia again. Splenectomy and sigmoid colon resection were performed immediately.Outcomes:Follow-up computed tomography showed no residual varices were observed after sigmoid colon resection.Lessons:Ectopic varices, which are rare sequelae of portal hypertension, need to be taken seriously because bleeding from these varices can be catastrophic. We report a case of isolated sigmoid variceal rupture and hemorrhage due to portal hypertension in cirrhosis. The patient experienced failure of endoscopic hemostasis and sigmoid colon venous coil embolization. She was eventually successfully brought to hemostasis by surgery.     

Isolated splenic metastases from gastric carcinoma:A case report and literature review

Isolated metastases to the spleen from gastric carcinoma is very rare.Only a few cases have been reported in the literature.We herein present a case of isolated splenic metastases in a 62-year-old man,occurring 12 mo after total gastrectomy for gastric carcinoma.The patient underwent a laparoscopic exploration,during which two lesions were found at the upper pole of the spleen,without involvement of other organs.A laparoscopic splenectomy was performed.Histological examination confirmed that the splenic tumor was a poorly differentiated adenocarcinoma similar to the primary gastric lesion.The postoperative course was uneventful and the patient has been well for 9 mo,with no tumor recurrence.The clinical data of 18 cases of isolated splenic metastases from gastric carcinoma treated by splenectomy were summarized after a literature review.To our knowledge,this is the first reported case of isolated splenic metastases undergoing laparoscopic splenectomy.     

Spontaneous internal jugular vein thrombosis: a case report

Internal jugular vein thrombosis (IJVT) is an elusive vascular disease that is rarely seen, with potentially lethal complications such as sepsis and pulmonary embolism. Spontaneous IJVT is considered when no apparent predisposing cause of thrombosis is present. A previously healthy, 31-year-old woman presented to the university-based emergency department because of painless swelling in the right anterior side of her neck. Physical examination revealed a painless, soft and immobile mass in the right anterior side of her neck beneath the sternocleidomastoid muscle, without hyperemia or local heat. On ultrasonographic examination, a hyperechogenic mass was visualized around the thoracic entrance of the right internal jugular vein, which was suggestive of a thrombus. The patient was administered intravenous antibiotic and low-molecular-weight heparin followed by oral coumadin as anticoagulant therapy. Her complaints were relieved within 5 days. She was completely well after 6 months. Venous thrombosis generally results from impaired blood flow locally or systemically that leads to activation of coagulation. Primary care physicians should sustain a high index of suspicion in patients who present with undiagnosed swelling in the neck, or other signs and symptoms attributed to IJVT.     

Primary splenic angiosarcoma with liver metastasis: A case report and literature review

Primary splenic angiosarcoma(PSA) is an unusual and highly malignant vascular tumour with a high rate of metastatic. Moreover, the research on prognosis of the disease is poor. The epidemiology, etiology, clinical diagnosis and treatment of the disease remain challenging, because case reports of the disease are few in number. In accordance with other malignant tumors, PSA is very aggressive, and the majority of patients in which this disease is found are at an advanced stage. Almost all patients die within 12 mo of diagnosis irrespective of treatment. We report here a woman who had complained of upper bellyache and anorexia for 10 d. Magnetic resonance imaging showed enlargement of the spleen with multiple heterogeneous masses in the lower pole of the spleen. A hand-assisted laparoscopic splenectomy was performed which allowed histopathologic diagnosis. The patient was diagnosed with PSA and liver metastasis, and succumbed to the disease 35 d after surgery. The literature was finished combined with the clinical features, diagnosis and management of PSA.     

Isolated splenic metastasis of endometrial cancer 12 years after treatment: A case report and literature review

Rationale:The spleen is an uncommon metastatic organ for malignant solid tumors because of its special anatomy and microenvironment. Isolated splenic metastasis of endometrial cancer is an extremely rare clinical event, with only 17 cases reported in literature.Patient concerns:We report the case of a 58-year-old woman with abdominal distension and nausea for 7 months who had undergone surgery and chemotherapy for endometrioid adenocarcinoma 12 years previously. A space-occupying lesion in the upper pole of the spleen was observed on an abdominal ultrasound.Diagnosis:The spleen was resected, and splenic metastasis of endometrial adenocarcinoma was histologically confirmed.Interventions:Splenectomy was performed, and no lymph nodes or other metastases were observed. The patient received postoperative chemotherapy with 6 cycles of docetaxel and carboplatin.Outcomes:The patient recovered well 11 months postoperatively, with no evidence of recurrence or metastatic disease.Lesson:Since the time interval between the diagnosis of primary endometrial cancer and splenic metastasis may be very long, it may be necessary to monitor the recurrence of endometrial cancer after primary treatment.     

Splenectomy in a case of splenic vein thrombosis unmasks essential thrombocythemia

We report a patient with splenic vein thrombosis (SVT) in whom splenectomy resulted in the unmasking of essential thrombocythemia (ET). He had portal hypertension with haematemesis, resulting in anaemia requiring repeated blood transfusions. Investigations revealed SVT. Following splenectomy, he suffered a transient ischaemic attack episode, associated with persistent thrombocytosis (> 2000 x 10(9)/l). Other myeloproliferative disorders were excluded and a diagnosis of ET was established. He responded to hydroxyurea but, due to financial constraints, he discontinued treatment and subsequently relapsed. The association of ET with SVT is rare and the diagnosis of ET was missed initially as the platelet count was normal prior to splenectomy.     

Isolated splenic metastasis from colorectal carcinoma

In general, surgical resection for metastatic colorectal adenocarcinoma rarely benefits more than a small percentage of patients long term. In the case of isolated splenic metastasis without evidence of other metastatic disease, splenectomy may increase survival times in patients with previously resected colorectal adenocarcinoma. Currently there are only five case reports involving isolated splenic metastases in the English-language literature. This article presents a sixth case and a review of the previous five cases in the literature, with a discussion on the possible diagnostic and therapeutic approaches to these rare but important cases and the apparently significant survival advantage of early diagnosis and treatment.The views expressed in this article are those of the authors and do not reflect the official policy or position of the Department of the Army, Department of Defense, or the United States Government.
