Idiopathic localized dilatation of the ileum in adults: findings on barium studies.

Abstract

Idiopathic localized dilatation of the ileum should be suspected whenever a sharply demarcated area of lobulated small bowel dilatation is seen in a middle-aged patient with occult GI bleeding. The axial orientation distinguishes this condition from small bowel diverticula (including Meckel's). The lack of surrounding mass, mucosal irregularity, hypermotility, or fistulae help differentiate it from other causes of small bowel dilatation.
