An unusual case of giant jejunal diverticula presenting radiologically as toxic megacolon.

ABSTRACT

Jejunal diverticulosis is an uncommon entity of the gastrointestinal tract. It involves the presence of multiple diverticula (pouches) in the jejunal wall. Jejunal diverticulosis is not so common, and the epidemiology is ill defined, but usually, it is known to affect the elderly more. They are considered from a pathophysiological point of view as motility disorders, structural defects, or high intraluminal pressures, with the result of prolapse of the mucosa of the jejunum through weak points of the intestinal wall. It represents a rare entity with different clinical presentations, ranging from being asymptomatic to life-threatening complications such as obstruction, bleeding, or perforation. Treatment depends on the presentation and can be conservative or surgical management.
