Omental ischemia.

Omental ischemia is a rare cause of acute abdomen. Clinical diagnosis is usually difficult because clinical signs and symptoms are similar to other common causes of abdominal pain. The most common differential diagnosis is acute appendicitis. Diagnosis is mainly based on ultrasound, and especially computed tomography scan analysis. There is, at present, no standard treatment modality for omental ischemia. When diagnosed by radiological imaging, omental ischemia can be managed conservatively. We hereby review incidence, etiology, pathology, clinical presentation, differential diagnosis, biological anomalies, radiological features, and treatment options of omental ischemia.
