Spontaneous idiopathic omental bleeding: a case report of rare cause of acute abdomen

Idiopathic omental hemorrhage is a rare cause of an acute abdomen, which is potentially life threatening. Here, we report a case of a 34-year-old male who presented to the emergency department with sudden, severe pain abdomen and abdominal distension for 1 day. There was no history of trauma, abdominal surgeries or any significant past medical history. The diagnosis was suspected on contrast computed tomography, which revealed hyperdense areas of blood in the peritoneal cavity with contrast extravasation from the omentum. The patient underwent successful emergency laparotomy, peritoneal lavage and greater omentectomy to achieve hemostasis.
