摘　　要：目的：探讨黄色肉芽肿性胆囊炎（XGC）的CT表现，以提高该病术前CT诊断水平。方法回顾性分析6例经手术病理证实的 XGC的CT表现。结果6例均可见不同程度胆囊壁增厚，其中弥漫性增厚4例，局限性增厚2例，增厚胆囊壁内均可见低密度结节或低密度带。4例胆囊黏膜线连续。增强扫描动脉期增厚胆囊壁大多表现为“夹心饼干征”。6例均可见胆囊结石，合并胆总管结石4例，合并胆管扩张3例。5例累及肝脏，与十二指肠、结肠肝曲及胃窦粘连各1例。结论增厚胆囊壁内低密度结节或低密度带、胆囊黏膜线连续是 XGC较具特征性的CT表现，有助于该病的诊断及鉴别诊断。Objective To investigate CT features of XGC in order to improve pre-operative diagnosis of the disease.Methods The CT features of 6 cases with XGC confirmed by histopathology were analyzed retrospectively.Results The gallbladder walls thick-ened in all 6 cases,diffusely thickened in 4 cases and focally thickened in 2 cases.Hypodensity nodules or bands in thickened walls were seen in all 6 cases.The continuous mucosal lines were observed in 4 cases.After contrast administration,the hypodensity band sign was seen in most cases in artery phase.Stones were found in all 6 gallbladders and in 4 common bile ducts,dilatation of biliary tract was seen in 3 cases.There were hepatic involvement in 5 cases,duodenal,hepatic flexure of the colon and antrum of the stom-ach adhesion with gallbladder was seen in 1 case respectively.Conclusion Hypodensity nodules or bands in thickened gallbladder walls and continuous mucosal line are characteristics of XGC,which are helpful in diagnosis and differential diagnosis.
