摘　　要：目的探讨局限型胆囊腺肌增生症(GBA)的CT分型及临床意义。方法搜集38例经手术病理证实的局限型GBA患者的临床及影像资料,男23例,女15例,平均年龄57岁。全部病例均行多层螺旋CT(MSCT)平扫及多期增强扫描,原始数据行CT薄层重组及多平面重组(MPR),根据CT表现对局限型GBA进行分型。结果38例局限型GBA中,基底型9例,胆囊底部帽状、半环状或扁平状轻度增厚;壁内型3例,底部局限性增厚向腔内隆起;乳头型24例,增厚底部呈乳头状向腔外凸出;混合型2例,底部增厚同时向腔内、外隆起。各型病例在平扫及多期增强扫描均可见分布于整个增厚壁内多发大小不等的罗-阿氏窦(RAS)。结论局限型GBA的CT分型有望为临床治疗及手术方案的选择提供参考依据。Objective Type focal Adenomyomatosis of Gallbladder（ GBA） CT classification and clinical significance.Methods Collect the focal of 38 cases of surgical pathology confirmed GBA clinical imaging data,male 23 cases,15 cases were female,average age of 57. All cases were row multislice CT（ MSCT） scan and multiphase enhancement scanning,original data row CT thin layer restructuring and multiplanar reformation（ MPR）,according to the CT manifestations of GBA focal type classification. Results 38 cases of focal GBA,basal type 9 cases,bonnet,half ring at the bottom of the gallbladder in thickness or flat. Wall type in 3 cases,at the bottom of the localized thickening of the lumen. 24 cases of nipple type,thickening of the bottom is papillary prominent outside the cavity. Mixed in 2 cases,thickening of the bottom at the same time to the internal and external cavity uplift. Various cases in both scan and multiphase enhancement scanning are distributed throughout the wall thickening in multiple sizes of Rokitansky Ashoff sinus（ RAS）. Conclusion Focal GBA CT classification can provide a reference for the choice of clinical treatment and surgery plan.
