Abstract

BACKGROUND : Angiomyxoma-related intussusception in adults is extremely rare. Herein, we report an adult man who presented with mechanical small bowel obstruction caused by ileo-colic intussusception triggered by an angiomyxoma of the terminal ileum and review the literature on this topic.
METHODS : A-40-year-old man was referred to Al-Ain Hospital with a clinical picture of small bowel obstruction. He has no previous abdominal surgery. Clinical examination showed a distended soft abdomen, and hyperactive bowel sounds. Abdominal ultrasound and computed tomography scan showed a doughnut sign confirming the presence of ileo-colic intussusception as the cause for small bowel obstruction. At laparotomy, a mass was found in the right iliac fossa. Right hemi colectomy was performed with ileo-colic anastomosis. An ileal pedunculated mass triggered the intussusception. Histopathology of the mass was diagnostic of an angiomyxoma of small bowel. Echocardiogram showed no atrial synchronous myxoma. The patient was discharged home with good general condition. At three years follow up, the patient remained asymptomatic without evidence of recurrence.
CONCLUSIONS : Myxoma of small bowel should be included in the differential diagnosis of small bowel obstruction in the young age group particularly if the diagnosis of intussusception was made preoperatively.
