Thymoma is an epithelial neoplasm of the thymus, which commonly lies in the anterior mediastinum and recurrences of thymoma generally are locally, and retroperitoneal recurrence is considered to be rare. A 46-year old Asian woman with invasive thymoma had undergone thymectomy 10 years ago. Computed tomography demonstrated a well-circumscribed mass in the left retroperitoneal space. The patient ...

OBJECTIVE To report an uncommon method of managing pancreatic fistulas and retroperitoneal abscess. CLINICAL PRESENTATION AND INTERVENTION A 50-year-old man was admitted with fever, abdominal pain, periumbilical fistula and pus in stool. Five months before admission, he underwent urgent necrosectomy (7 days after onset of pain) and subsequently two more surgeries for necrotizing pancreatitis....

Lateral approach spine surgery provides effective interbody stabilization, and correction and indirect neural decompression with minimal-incision and less invasive surgery compared with conventional open anterior lumbar fusion. It may also avoid the trauma to paraspinal muscles or facet joints found with transforaminal lumbar interbody fusion and posterior lumbar interbody fusion. However, beca...

Retroperitoneal hemangiomas are very rare. This paper presents the case of a 71-year-old female patient with giant cavernous hemangioma of the retroperitoneum who underwent surgical treatment for abdominal pain and left lower limb edema. Interventional staged treatment with percutaneous transcatheter arterial embolization prior to surgery was considered. Radical resection of the tumor was perfo...

Multiple myeloma, a plasma cell neoplasm, presents most commonly with anemia, hypercalcemia, renal failure, and bone pain. Only few cases of clinical aggressive presentation associated with bleeding were reported in the medical literature. The reported cases included gastrointestinal bleeding and cardiac tamponade. Spontaneous retroperitoneal haemorrhage as initial presentation has not been so ...

A 69-year-old man presented at the hospital with complaints of prolonged stomach pain extending from the week prior. Enhanced computed tomography (CT) revealed a low density area in the retroperitoneal space. A radiologist diagnosed the patient with retroperitoneal fibrosis. One week later, an enhanced CT revealed an exponential increase of the low density area and slight right hydronephrosis. ...

Percutaneous nephrostomy is a safe procedure, performed routinely by interventional radiologists, and has a low complication rate. We report an unusual case of a fractured nephrostomy tube, retained within the kidney, having its fractured end trapped within the healed retroperitoneal tract. The catheter was retrieved by snaring it, using a percutaneous access to the collecting system. We descri...

We report an extremely rare case of malignant Triton tumor developing in the retroperitoneal space in a patient with neurofibromatosis type 1. A 21-year old man who had been diagnosed with neurofibromatosis type 1 was admitted to our hospital with the chief complaint of a palpable abdominal mass. Abdominal computed tomography revealed a huge heterogeneous tumor measuring approximately 17 cm in ...

OBJECTIVE To describe the clinical features, surgical and histologic findings, biological behavior, and outcome of dogs with retroperitoneal sarcomas. DESIGN Retrospective study. ANIMALS 14 dogs. PROCEDURES Medical and pathology records from 1992 to 2002 of dogs with tumors originating in the retroperitoneal space were reviewed. Dogs with retroperitoneal tumors originating from the adrena...

BACKGROUND Retroperitoneal enterogenous cysts are uncommon and adenocarcinoma within such cysts is a rare complication. CASE PRESENTATION We present the third described case of a retroperitoneal enterogenous cyst with adenocarcinomatous changes and only the second reported case whereby the cyst was not arising from any anatomical structure. CONCLUSION This case demonstrates the difficulties...
