Abstract
Giant colonic diverticulum (GCD), defined as a diverticulum larger than 4 cm, is a rare entity that is generally a manifestation of colonic diverticular disease. Because of its rarity and its variable and non-specific presentation, the diagnosis of GCD depends mainly on imaging findings. Knowledge of the spectrum of radiographic and CT features of the GCD is important in making the correct diagnosis and potentially preventing complications. This review focuses on imaging findings characteristic of GCD as well as its complications and radiographic mimics.
Teaching points
• Giant colonic diverticulum is a rare complication of diverticulosis.
• The most common symptom is abdominal pain presenting in approximately 70 % of patients.
• Diagnosis is based on imaging findings with plain abdominal radiographs and MDCT.
• Treatment consists of en
bloc resection of the diverticulum and affected adjacent colon.
