Haemoperitoneum is usually associated with trauma, ruptured aortic aneurysm, ectopic pregnancy, bleeding from an ovarian follicle or hepatic tumor. Idiopathic spontaneous haemoperitoneum is a very rare pathology, presenting more often with diffuse abdominal pain, associated with cardiovascular instability. We discuss a case of idiopathic spontaneous haemoperitoneum in a 28-year-old healthy woman, presenting with right lower quadrant syndrome. A review of the literature and practical considerations towards this rare affection are presented.
