多排螺旋CT鉴别诊断黄色肉芽肿性胆囊炎和胆囊癌

摘要

Objective To explore the diagnostic value of multi-detector CT (MDCT) in differentiating xanthogranulomatous cholecystitis (XGC) from gallbladder cancer (GBC).Methods CT manifestations of 11 XGCs and 20 GBCs proved pathologically were analyzed retrospectively.All patients underwent MDCT before operation, and CT signs of XGC and GBC were analyzed.Results XGC and GBC were significant different according to CT findings including the mode of GB wall thickening, the mucosal line being continuous or not, having intra-mural hypo-attenuated nodules and intra-hepatic bile duct dilatation or not (P＜0.05).The numbers of patients with infiltration of hepatic and adjacent tissue were not significant difference, but the form of changes of adjacent tissues was different between XGC and GBC.Conclusion MDCT scanning can provide objective basis for differentiate XGC from GBC.%目的 探讨多排螺旋CT(MDCT)鉴别诊断黄色肉芽肿性胆囊炎和胆囊癌的价值.方法 回顾性分析经手术病理证实的11例黄色肉芽肿性胆囊炎(XGC)和20例胆囊癌(GBC)的资料,所有患者术前均接受MDCT检查,并分析两种病变的CT征象.结果 胆囊壁的增厚方式、黏膜线情况、是否有壁内低密度结节和胆道梗阻在XGC和GBC患者间差异有统计学意义(P均＜0.05).XGC与GBC患者发生邻近肝脏及周围组织改变的病例数差异无统计学意义(P＞0.05),但邻近组织改变的形式不同.结论 MDCT扫描可为鉴别诊断黄色肉芽肿性胆囊炎和胆囊癌提供客观依据.
