Heterotopic mesenteric ossification: report of a case and review of the literature.

Heterotopic mesenteric ossification (HMO) is a distinct intra-abdominal ossifying pseudotumour that typically occurs in men, almost always after surgery or abdominal trauma, and frequently presents with symptoms of intestinal obstruction. We herein describe a case of HMO occurring in a 42-year-old Iranian man with a history of abdominal blunt trauma. He underwent partial small intestinal and its mesentery resection. The postoperative course was uneventful. Now he is in good condition after 6 months.
