目的通过对16例肝门区胆管癌的分析,总结其CT表现特点,评估CT对其诊断的价值。方法收集分析16例经CT诊断的肝门区胆管癌病例,全部病例均经手术及病理证实。采用GEProSpeedII全身螺旋CT,病例均行腹部CT平扫及增强延迟扫描。结果16例肝门区胆管癌中浸润型10例。巨块型4例,管内型2例。肿瘤外的CT表现:肝内胆管均有不同程度扩张,3例有胆系结石,1例可见肝门及腹膜后肿大的淋巴结。增强扫描时病灶多具有“慢进慢出”即延时强化特征。结论CT薄层增强延时扫描是诊断肝门区胆管癌的有效方法。
Objective To analyze the characteristics of 16 cases of hilar cholangiocarcinoma and summarize its CT features and evaluate the value of CT in its diagnosis. Methods 16 cases of hilar cholangiocarcinoma diagnosed by CT were collected and analyzed. All the cases were confirmed by operation and pathology. Using GEProSpeedII whole-body spiral CT, all patients underwent CT scan of the abdomen and enhanced delayed scan. Results 16 cases of hilar cholangiocarcinoma in infiltration in 10 cases. 4 cases of bulky type, 2 cases of tube type. Tumors outside the CT performance: intrahepatic bile ducts have varying degrees of expansion, 3 cases of gallstones, 1 case of hepatic portal and retroperitoneal lymph nodes. Enhance the scan when the lesions have more “slow into slow out ” that delay enhanced features. Conclusion CT thin-layer enhanced delayed scan is an effective method for the diagnosis of hilar cholangiocarcinoma.
