Abstract

INTRODUCTION:

Intussusception in adults accounts for less than 5% of all intussusceptions. It occurs when a segment of intestine invaginates into itself.

PRESENTATION OF A CASE:

We report a case of ileocolic intussusception in an adult caused by a giant ileal lipoma.

DISCUSSION:

Intussusceptions can be classified as ileocolic, ileocecal, colo-colic and ileo-ileal. Most are due to neoplasms (60% malign and 24-40% benign). In the colon, the possibility of malignancy is higher than in small intestine. Lipomas are the most common benign mesenchymal intestinal tumors, accounting for less than 5% of all gastrointestinal tumors. They are more frequent in colon than small intestine. Small lipomas (less than 2cm) are usually asymptomatic. Larger lesions may produce symptoms such as abdominal pain, obstruction or intussusception. Lipomas can be diagnosed with endoscopy, capsule endoscopy, barium enemas, CT and US.

CONCLUSION:

Intussusceptions in adults is a rare condition, most of them are caused by a malign neoplasms followed by benign neoplasms. US and CT are useful for diagnosis. Surgery is mandatory.
