Intraperitoneal focal fat infarctions (i.e. epiploic appendagitis or omental infarction) are due to acute inflammation of the intraperitoneal fat secondary to vascular compromise causing acute abdominal pain, mimicking acute appendicitis or acute diverticulitis.

They are usually self-limiting and managed conservatively. In this patient, diagnostic laparoscopy was performed due to persistent severe pain, which confirmed the diagnosis of epiploic appendagitis arising from the surface of the ascending colon. This was excised and the patient recovered uneventfully.
