Abstract and Introduction


Diverticular disorders of the colon are common among the aging population of industrial countries. About 50% of individuals older than 60 years of age develop diverticulosis predominantly involving the sigmoid, and 10–20% of them will experience complications during their lifetime, such as diverticulitis, hemorrhage, perforation and fistula to the adjacent organs.[1,2] However, a giant sigmoid diverticulum (GSD) is a rare complication and may present a diagnostic and therapeutic challenge for those who are unfamiliar with the condition.[3–6]

The majority of publications about GSD have been isolated case reports in the surgical literature. This article reviews the imaging and management of GSD.
