摘　　要：胆囊腺肌增生症（GAM）是发生于胆囊的良性增生性病变,是胆囊壁黏膜增生突入增厚的胆囊壁肌层,形成憩室样病变（即罗-阿氏窦）,分为弥漫型、节段型和基底型3种类型.其临床表现无特异性,CT检查表现有助于该病的诊断.2010年7月至2013年5月无锡市第二人民医院收治了16例基底型GAM患者.局限性增厚的胆囊底部壁内“罗-阿氏窦”和“小帽征”是基底型GAM的CT检查的典型表现.CT增强扫描检查对基底型GAM的诊断具有重要价值.Adenomyomatosis of the gallbladder （GAM） is an acquired,benign proliferative lesion of the gallbladder which is characterized by mucosal proliferation with invaginations and diverticula penetrating into the thickened muscular layer （Rokitansky-Aschoff sinuses）.GAM consists of 3 types：diffuse,segmental and fundus GAM.There is no specific presentation of GAM,and computed tomography is helpful for the diagnosis of this disease.From July 2010 to May 2013,16 patients with fundus GAM were admitted to the Second People＇s Hospital of Wuxi.Rokitansky-Aschoff sinuses and calotte sign at the thickened muscular layer of the fundus of the gallbladder are the typical presentation of the fundus GAM.Enhanced computed tomography examination is of great importance for the diagnosis of the fundus GAM.
