INTRODUCTION Heterotopic ossification (HO) refers to the formation of bone in non-ossifying tissue. Heterotopic mesenteric ossification is a rare form of HO that is characterized by the formation of an ossifying pseudotumour at the base of the mesentery, usually following abdominal surgery. PRESENTATION OF CASE We describe a case of mesenteric HO in a young male who presented for elective ventral incisional hernia repair following a stab wound to the abdomen requiring exploratory laparotomy 21 months earlier. Preoperative workup was unremarkable, but a hard, bone-like lesion was noted to encircle the base of the mesentery upon entering the abdomen, consistent with HO. The lesion was excised with close margins, and his hernia was repaired without incident. DISCUSSION Traumatic HO describes the ossification of extra-skeletal tissue that specifically follows a traumatic event. It usually occurs adjacent to skeletal tissue, but has been occasionally described in the abdomen as well, usually in patients who suffer abdominal trauma. Overall the prognosis of HO is good, as it is considered a benign lesion with no malignant potential. However, the major morbidity associated with mesenteric HO is bowel obstruction. CONCLUSION The size, location, and symptoms related to our patient's mesenteric HO put him risk for obstruction in the future. As a result, the mass was surgically excised during his ventral hernia repair with good outcomes.
