Colorectal intussusception caused by a pedunculated lipoma: A rare case report

Abstract

Intussusception is a rare condition in adults and can have various causes, including cancer. A man aged 35 presented to the emergency department with abdominal pain, abdominal distension, and rectal bleeding. A CT scan revealed that a lipoma in the recto-sigmoid region had caused the intussusception, resulting in a mechanical obstruction. To treat this, the intussusception was reduced, and part of the sigmoid was removed with an end colostomy. It is essential to consider the possibility of malignancy when managing adult intussusception as reducing a malignant segment may cause dissemination. While intussusception caused by non-malignant lesions such as lipomas is known to occur, it is more common in the right and transverse colons.
