Idiopathic omental bleeding.

Omental bleeding without any evidence of trauma, aneurysms, or other pathology has been rarely described in the literature. We report a case of a 24 year-old female on aspirin/acetaminophen/caffeine for migraines who presented with abdominal pain and tachycardia. Computed tomography angiography revealed active extravasation in the right lower quadrant. During exploratory laparotomy, a small bleeding artery within the greater omentum was suture ligated, and two liters of fresh and clotted blood were evacuated. The patient recovered successfully. We review the diagnosis and management of this rare condition.
