Acute Adult Jejuno-Jejunal Intussusception Caused by a Giant Lipoma

Abstract

Acute abdominal pain secondary to intussusception is rare in adults and mainly caused by malignancy (70-90%), whereas in childhood intussusception’s etiology is mostly idiopathic (90% of cases). Gastrointestinal lipomas, especially in small bowel, represent an unusual cause of intussusception with complete intestinal obstruction or bleeding (acute or chronic) from mucosal ulceration. In acute settings, computed tomography (CT) should be confidently considered the gold standard for diagnosis. In adulthood, surgical management of acute symptomatic intussusception caused by lipoma is mandatory. We report a case of complete jejunal obstruction with intussusception due to 5 cm submucosal lipoma.
