摘　　要：目的探讨黄色肉芽肿性胆囊炎(XGC)的CT表现,以提高黄色肉芽肿性胆囊炎诊断水平。方法分析经手术、病理证实的11例黄色肉芽肿性胆囊炎的CT、临床及手术病理资料。观察胆囊壁厚度、壁内低密度结节、胆囊内壁、黏膜线、胆囊壁及受累肝组织强化程度、胆囊内有无结石,以及胆囊周围的变化。结果11例均见不同程度的胆囊壁增厚及壁内结节,9例胆囊壁内面光滑,6例显示黏膜线,3例胆囊增大,4例缩小,4例发现胆囊结石,6例侵犯肝脏,3例胆囊周围炎性浸润,6例伴有胆道扩张。结论增厚的胆囊壁内低密度结节(三明治征)和完整的黏膜线较具特征性。Objective To analyze CT features of xanthogranulomatous cholecystitis（ XGC） so that to improve the accuracy of diagnosis. Methods The data of CT,cllnic and operation in 11 cases with XGC proved pathologically were analysed. The following CT features were analyzed ： the cholecystic wall thickness, intramural hypoattenuated nodules, inner wall, mucosal line, patterns of enhancement of thickened wall, involved liver tissue and the presence of stones. The changes around the gallbladder were also noticed. Results The gallbladder wall was thickened and intramural hypoattenuated nodules were seen in all patients. The inner wall of gallbladder was smooth in 9 patients, the mucosal line was observed in 6 cases, the size of gallbladder was enlarged in 3 while 4 gallbladders were smaller than normal. Stones were found in 4 gallbladders. There were hepatic involvement in 6 ,pericholecystic infiltration in 3 and dilatation of biliary tract in 6 cases. Conclusion CT features of thickened gallbladder wall with intramural hypoattenuated nodules （ sandwich sign） and continuous mucosal line were characteristic of XGC.
