摘要
目的探讨CT对黄色肉芽肿性胆囊炎的诊断价值。方法男女患者各1例,男59岁,女80岁,均行CT平扫及增强检查,并经手术病理证实,对其CT征象结合文献复习进行回顾性分析。结果CT扫描显示,2例均见胆囊壁弥漫性增厚,壁内低密度结节和低密度带;胆囊内壁光整,囊腔形态规则,有不完整黏膜线;2例肝胆界面均存在、光整;都有胆囊结石,其中,1例合并有胆总管下端结石。结论增厚胆囊壁内多发结节状或条带状低密度影是黄色肉芽肿性胆囊炎的特征性CT表现;胆囊内壁光整、囊腔形态规则是鉴别本病与胆囊癌不可忽视的重要CT征象。
Objective To assess the usefulness of CT scanning in the diagnosis of xanthogranulomatous cholecystitis（XGC）. Method Two patients who comprised a 59 year-old man and a 80 year-old worman with surgically and pathologically proved XGC underwent CT scans of the abdomen before and after contrast enhancement.CT findings of XGCs in all 2 cases were retrospectively analyzed together with review of the literature. Results CT scanning showed that the lesions of XGCs in all 2 cases presented as the diffusive thickening of cholecystic walls,intramural hypodense nodules and hypodense bands,smooth and complete inner walls of gallbladders,regular shape of cholecystic cavities and incomplete mucosal lines. There were smooth and complete interface between the liver and the gallbladder and cholecystolithidsis in 2 cases,of whom,one case associated with calculi of inferior-end common bile ducts. Conclusions Multiple nodular-or band-form hypodense shadows in the thickened cholecystic walls are specific CT findings of XGC,while smooth and complete inner wall of the cholecyst and regular shape of cholecystic cavity are important CT signs to differentiate this disease from cholecystic carcinoma.
