目的评价CT动态增强在肿块型周围型胆管细胞性肝癌诊断中的价值。方法回顾性分析28例经病理证实的肿块型周围型胆管细胞性肝癌的CT资料。所有病例均进行CT动态增强扫描,包括动脉期、门脉期和延迟期。观察指标包括:病灶数目、部位、形态、边缘、大小、密度以及动态增强模式。结果肿瘤大小约1.5~13cm,平均(5.8±2.1)cm。15例有周围性胆管扩张,5例有包膜回缩征,2例有卫星灶,13例有淋巴结肿大。平扫时肿块呈低密度。动态增强时,动脉期有20例、门脉期有21例见肿块周边环状强化,延迟期有26例可见肿块中心不均匀强化。结论CT动态增强在肿块型周围型胆管细胞性肝癌中有重要的诊断价值。
Objective To evaluate the value of CT dynamic enhancement in the diagnosis of cholangiocellular carcinoma of the mass type. Methods The CT data of 28 cases of pathologically confirmed cholangiocarcinoma of the liver were retrospectively analyzed. All patients underwent dynamic contrast-enhanced CT scan, including the arterial phase, portal phase and delayed phase. Observations included: number of lesions, location, morphology, margin, size, density, and dynamic enhancement pattern. Results The tumor size was about 1.5 ~ 13cm, with an average of (5.8 ± 2.1) cm. There were 15 cases of peripheral bile duct dilatation, 5 cases of capsular retraction, 2 cases of satellite lesions and 13 cases of lymph nodes. Mass scan showed low density. Dynamic enhancement, the arterial phase in 20 cases, 21 cases of portal venous enhancement seen around the ring, 26 cases of delayed visible uneven mass center enhancement. Conclusion CT dynamic enhancement in the diagnosis of cholangiocarcinoma of the mass type has important diagnostic value.
