Massive Lipomatosis of the Small Intestine Causing Intussusception

Abstract EN

Lipomatosis is a rare condition characterized by diffuse, unencapsulted adipose tissue deposition.

Intestinal involvement is rare, and presentation as intussusception is rarer still.

We report a 40-year-old man who presented with abdominal pain and fecal urgency.

Abdominal CT scan showed a protuberant ileo-cecal valve, with intussusception of the ileum into the cecum.

The mucosal surface of the resected bowel was bulbous and protuberant, showing loss of mucosal folds, and there was an 8 × 5 × 5 cm mass prolapsing into the ileo-cecal valve.

Microscopically there was abundant adipose tissue in the submucosa with an unremarkable mucosa.

The patient recovered uneventfully with only occasional cramping in the left abdomen.
