Spontaneous haemoperitoneum is a rare condition with a variety of aetiologies. 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.

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. We discuss the management approach for such patients with spontaneous haemoperitoneum.
