Retroperitoneal haematoma is a rare clinical entity with variable etiology. It can happen spontaneously, without any obvious precipitating factors, the so-called spontaneous retroperitoneal haematoma. There is no general consensus as to the best management plan for patients with retroperitoneal haematoma. Polyarteritis nodosa (PAN) is a rare cause of retroperitoneal haematoma. Here we report re...

BACKGROUND Retroperitoneal haematoma could be caused by different factors. It is increasing due to an increase in the use of antithrombotic and anticoagulant therapy. Diagnosis of retroperitoneal haematoma forms a big challenge in daily clinical practice. Patients with retroperitoneal haematoma could present with leg paresis, abdominal pain, shock or abdominal compartment syndrome. Retroperiton...

Purpose Colonic perforation is a lethal condition presenting high morbidity and mortality in spite of urgent surgical treatment. This study investigated the surgical outcome of patients with colonic perforation associated with retroperitoneal contamination. Methods Retrospective analysis was performed for 30 patients diagnosed with colonic perforation caused by either inflammation or ischemia...

BACKGROUND Adequate operation interspace is the premise of laparoscopy, and carbon dioxide (CO2) was an ideal gas for forming lacuna. A retroperitoneal space is used to form operation interspace in retroperitoneal laparoscopic radical nephrectomy by making ballooning, and the retroperitoneal space has no relative complete and airtight serous membrane, therefore CO2 absorption may be greater in ...

Primary retroperitoneal malignant lymphoma is rare, and primary retroperitoneal indolent B-cell lymphoma has not been reported. A 64-year-old woman presented anuria. Imaging techniques showed large retroperitoneal mass, and biopsies from it revealed non-Hodgkin indolent B-cell lymphoma (small lymphocytic lymphoma/chronic lymphocytic lymphoma). The tumor appeared retroperitoneal primary and extr...

neuroblastoma is the most common extracranial solid tumor in childhood. in different classification of neuroblastomas, a subset of undifferentiated or poorly differentiated tumors with bizarre histological features has been mentioned. a 3-year-old girl presented with abdominal pain. her haematological and biochemical parameters were normal except her urinary vanelylmandelic acid level was elevat...

paragangliomas are tumors that originate from extra-adrenal medullary neural crest derivatives. they are rarely located in retroperitoneal space. these tumors are often discovered incidentally during imaging studies performed for other reasons.periampullary cancers include adenocarcinomas arising from the pancreas, ampulla of vater, duodenum or distal common bile duct. the exact site of origin ...

BACKGROUND Retroperitoneal schwannomas are very rare and are usually found incidentally. CASES REPORT Two rare cases of retroperitoneal schwannomas are reported. Both were incidentally found during US scans for non-specific epigastric pain and were initially diagnosed as non-secreting retroperitoneal tumors. The diagnosis was confirmed by CT scan. In both patients the tumors were resected. Th...

Retroperitoneal fibrosis is characterized by development of extensive fibrosis, leading to entrapment and obstruction of retroperitoneal structures, notably the ureters. In most cases, the etiology is unknown. It is occasionally associated with autoimmune diseases. Response to corticosteroids and immunosuppressive therapy suggest it is probably immunologically mediated. The symptoms and signs a...
