【摘要】 目的：探讨肝内胆管细胞癌CT增强征象的诊断价值及其病理基础。材料与方法：13例经病理证实的肝内胆管细胞癌行CT平扫及增强检查，其中部分病例加做CT延迟扫描。结果：13例CT平均表现低密度，伴肝内胆管扩张6例（6／13），合并肝内胆管结石4例；增强扫描线样强化5例（5／13），网格样强化4例（4／13），给节状强化2例，无明显强化2例。病理显示肝内胆管细胞癌纤维组织丰富，血管稀少。结论：CT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。更多还原

【Abstract】 Purpose: To evaluatc contrast - enhanced CT by correlating the CT findings with pathologic basis. Materials and Methods: thirteen patients with intrahepatic cholangiocarcinoma proven pathologically were performed unenhanced CT scan and contrast- enhanced CT scan. Four patients were taken delayed CT scan too. Results: Hypodense areas were show by uncnhanced CT scan in the all patients. Dilatation of intrahcpatic bile ducts was found in six patients. There were stoncs in four patients. On contrast enhanced CT scan. Line enhancement was scen in five patients, Net enhancement in four patients and nodule enhancement in two patients. In the pathological specimens, extensive fibrosis and minimal blood vessel were shown. Conclusion: Both hypodense in unenhanced CT scan and line or net enhancement is useful for diagnosis and differential diagnosis in intrahpatic cholanglocarcinoma.更多还原
