Regardless of the cause, it is invariably a life-threatening condition that requires urgent diagnosis and management. The most common causes of spontaneous haemoperitoneum include gynaecological, hepatic, splenic and vascular causes. However, here, we present a rare case of spontaneous haemoperitoneum secondary to idiopathic omental venous malformation.<\/jats:p>\n               <jats:p>Our patient presented with acute onset of right iliac fossa pain, and a CT scan revealed a massive haemoperitoneum. A laparoscopic converted to open laparotomy was performed to diagnose and treat the patient.
