A Case of Intussusception Due to Prolapsed Irreducible Lipoma of the Cecal Terminal Ileum

Abstract

Small–bowel lipoma is relatively rare. We report a case of prolapsed irreducible lipoma of the cecal terminal ileum causing transversal intussusception.
A 59–year–old man with intermittent abdominal pain and found in colonoscopy elsewhere to have a transverse colon tumor was hospitalized for worsening pain. Computed tomography (CT) showed ascending and transversal colon intussusception with a low–density mass at its apex, diagnosed as lipoma. Despite reducing of the intussuception, pain still remained, necessitating ileocecal resection yielding a specimen containing a 45×40×78 mm pedunculated tumor histopathologically diagnosed as prolapsed irreducible lipoma of the cecal terminal ileum.
