目的:观察肝内胆管细胞癌的 C T特征及其病理基础。方法:13 例经病理证实的肝内胆管细胞癌均行 C T 平扫及增强扫描,其中部分病例加做 C T延迟扫描;13 例肝内胆管细胞癌均行病理切片观察。结果:13 例 C T均表现低密度,伴肝内胆管扩张6 例,合并肝内胆管结石4 例;增强扫描呈线样强化5 例,网格样强化4 例,结节状强化2 例,无明显强化2 例。病理切片显示肝内胆管细胞癌纤维组织丰富,血管稀少,这是肝内胆管细胞癌 C T增强扫描呈各种各样强化的病理基础。结论: C T平扫低密度而增强呈线样及网格样强化,对肝内胆管癌有诊断和鉴别诊断价值。
Objective: To observe the C T characteristics and pathological basis of intrahepatic cholangiocarcinoma. Methods: CT scans and CT scans were performed in 13 cases of intrahepatic cholangiocarcinoma confirmed by pathology. In some cases, CT delayed scans were performed; 13 intrahepatic cholangiocarcinomas were observed by pathological sections. Results: 13 cases showed low density of C T with intrahepatic bile duct dilatation in 6 cases and 4 cases of intrahepatic bile duct stones; enhanced scan showed linear enhancement in 5 cases, grid-like enhancement in 4 cases, and nodular enhancement in 2 cases. No significant enhancement in 2 cases. Pathological sections showed that intrahepatic cholangiocarcinoma was rich in fibrous tissue and scarce blood vessels. This is a pathological basis for enhanced CT scans of intrahepatic cholangiocarcinoma. Conclusion: CT plain scan has low density and enhanced linear and grid-like enhancement, and has diagnostic and differential diagnostic value for intrahepatic cholangiocarcinoma.
