摘　　要：目的探讨局限型胆囊腺肌增生症的声像图特征及分类,提高超声诊断与鉴别诊断能力。方法对45例局限型胆囊腺肌增生症的超声声像图特征及术后病理结果进行对照分析。结果病灶多位于胆囊底部,可伴发于胆囊结石及胆囊炎,声像图表现可分为三类:(1)厚壁型胆囊壁局限增厚,可伴多个小囊状无或低回声,和/或斑点状强回声伴"彗星尾"征。(2)结节型局限于胆囊壁间、单发、类圆形均质低回声,边界清晰。(3)多囊型胆囊底部多房囊状改变,边缘光滑,后方回声增强。胆囊壁黏膜层及浆膜层均连续完整,与肝脏境界清楚。结论超声对不同类型局限型胆囊腺肌增生症有较高的诊断价值。Objective To explore the features and classifications of focal adenomyomatosis of gallbladder by ultrasonography and to improve uhrasoud diagnosis and differential diagnosis. Methods Sonograms of 45 patients with focal adenomyomatosis of gallbladder confirmed by histopathology were reviewed. Results Focal adenomyomatosis was most common in the gallbladder fundus, and often associated with gallstones and chronic cholecystitis. Sonograms could be divided into three kinds： （1） Thickened wall type： small focal area of thickened wall with a bright echogenic focus with a distal comet-tail artifact. （2） Adenomyoma： focal intramural nodular, with hypoechoic and masslike and smooth boundary. （3） Multiple cystic type： multiple cystic spaces within gallbladder fundus. Gallbladder wall was clear in all the cases. Conclusions Uhrasonography plays an important role in diagnosis of different kinds of focal adenomyomatosis of gallbladder.
