Abstract

Intussusception occurs mostly in children and rarely (only about 5% of cases) in adults. In contrast to pediatric intussusception, most cases of adult intussusception result from benign or malignant tumors and is usually treated with surgical resection. Here, we present a case of chronic intussusception in adult. It was induced by lipomas in jejunum. A 57-year-old woman complained of intermittent, colicky abdominal pain and distention for about 1 month. A 10 x 20 cm sized, soft mass was palpable in the left abdomen during the development of pain. Abdominal computed tomography scan revealed a concentric ring of bowel with intramural thickening. At laparotomy, jejuno-ileal intussusception was identified and two polypoid masses were recognized after manual reduction. The masses and jejunal segment were resected. Microscopic examination of the masses showed the features of submucosal lipomas.
