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.
巨大结肠憩室（GCD）定义为直径大于4厘米的憩室，是一种罕见的疾病，通常是结肠憩室病的一种表现。由于其罕见性以及表现多样且不具有特异性，GCD的诊断主要依赖于影像学检查结果。了解GCD的X线和CT特征谱对于做出正确诊断以及潜在地预防并发症很重要。本综述重点关注GCD的影像学特征、并发症以及影像学上的相似疾病。要点 • 巨大结肠憩室是憩室病的一种罕见并发症。• 最常见的症状是腹痛，约70%的患者会出现。• 诊断基于腹部平片和MDCT的影像学检查结果。• 治疗包括整块切除憩室及受影响的相邻结肠。
