摘要
目的回顾分析经病理证实的肝内周围型胆管细胞癌的CT影像表现,以提高术前诊断准确率。方法本组17例病例采用PQ-2000S单排螺旋CT平扫及三期增强扫描。结果CT平扫显示肿块呈不规则形态(13例)或类圆形(4例),58.8%患者病灶呈低或稍低密度。增强扫描动脉期病灶无明显强化或边缘轻-中度强化,门静脉期及延迟扫描病灶强化逐渐明显,部分病例有逐渐填充趋势;肿块多合并肝内胆管扩张、肝门淋巴结肿大、附近肝叶萎缩等间接征象。结论肝内周围型胆管细胞癌CT扫描有较特征性影像表现,结合AFP等检查可与肝细胞癌和肝血管瘤等肝内其他占位病变相鉴别。
Objective This study aims to improve the accuracy of diagnosis of peripheral cholangiocarcinoma by CT scan. Methods Results of plain and enhancement CT scan using PQ-2000S CT scanner from seventeen cases, including 11 males and 6 females, of peripheral intrahepatic cholangiocarcinoma proven by surgery or biopsy were retrospectively analyzed and examined. Results Lesion images from 13 patients showed irregular shape and rounded or ovoid in another 4 cases. 58.8% of patients had low attentuation lesions. The lesions were not clear or light-middle enhancement on the arterial phase, but gradually enhanced and obvious on the portal phase. Hepatic lobe atrophy was found in 6 patients, intrahepatic cholangiectasis in 12 cases and metastasis of lymph nodes in 8 cases. Conclusion Combined with AFP detection, CT scan can distinguish peripheral cholangiocarcinoma from hepatocellular carcinoma and hemangioma in liver.
