A 40-year-old man admitted for multiple pelvic bone fractures and undergoing exploratory laparotomy twice for suspect intraperitoneal hemorrhage and bowel perforation suffered small bowel obstruction. 3 days after the second laparotomy, small bowel obstruction was necessitating long tube insertion. 6 days after the second laparotomy, this conservative therapy failed, necessitating surgery. Dense adhesions found involving the jejunum required about 1 meter of small bowel to be resected. Histologically, the resected specimen showed ossification within the fibrous septa and thickening such as heterotopic ossification of soft tissue, definitively diagnosed as heterotopic mesenteric ossification. Postoperatively, the man was treated for heterotopic ossification of soft tissue using NSAIDs and cimetidine to prevent recurrence. He was remained disease free in the three years since surgery.
