INTRODUCTION Spontaneous retroperitoneal bleeding is a rare but potentially life-threatening event of varied etiology. Herein we report a case of bilateral non-traumatic retroperitoneal hemorrhage. CASE PRESENTATION A 50-year-old Greek man, who was on a non-steroidal anti-inflammatory agent (nimesulide) for ankylosing spondylitis, presented with a right retroperitoneal hematoma combined with ...

Spontaneous retroperitoneal hemorrhage is a distinct clinical entity that can present in the absence of specific underlying pathology or trauma and is typically associated with anticoagulation therapy. We report a case of a 74-year-old female patient with a cerebral infarction related to atrial fibrillation who developed a spontaneous lumbar arterial hemorrhage complicating heparin therapy. The...

Unstable pelvic ring disruptions are frequently associated with hemodynamic instability. Although the source of hemorrhage can be from multiple sites, the severity and type of pelvic disruption strongly correlates with retroperitoneal blood loss. Pelvic stabilization in the early posttraumatic phase is reported to provide an effective means of controlling this retroperitoneal hemorrhage. Pelvic...

Primary retroperitoneal cavernous hemangioma (PRCH) in an adult is extremely rare. We report on the diagnosis and treatment of a patient with PRCH with subtle clinical features and atypical findings on imaging scans. A 38-year-old man was admitted to hospital with a 5-day history of epigastralgia after alcohol drinking. Using various imaging methods, we found a giant cyst-like retroperitoneal m...

We report the case of an elderly woman with polycythemia vera submitted to bone marrow biopsy who developed retroperitoneal hemorrhage as a result of direct penetration of the needle through the iliac crest, with damage to the iliolumbar artery, the first branch of the hypogastric artery.

We report a case of spontaneous rupture of the common iliac artery associated with fibromuscular dysplasia (FMD). A 21-year-old previously healthy male presented with acute onset of colic pain, suspected to be caused by a ureteral stone. Abdominal computed tomography and angiography revealed a retroperitoneal hematoma caused by rupture of the common iliac artery. In spite of an emergency operat...

Spontaneous, nontraumatic retroperitoneal hemorrhage or Wunderlich syndrome (WS) is a rare but potential life-threatening condition. In most patients a bleeding renal neoplasm is the cause of the retroperitoneal hematoma. The management of this condition includes a conservative approach in the hemodynamically stable patients and active treatment in the unstable patients. Active treatment includ...
