目的研究周围型胆管细胞癌运用CT检查的影像学表现以及相应的诊断。方法我院选择2010年4月至2012年10月间进行诊治的84例周围型胆管细胞癌,对所有患者进行CT影像学检查。结果经过CT检查确诊,50例患者的病灶位于肝右叶,占59.52%;58例患者的病灶囊性或者多囊性,占69.6%;60例患者表现为边缘分叶怔,占71.43%;56例患者病灶周围胆管扩张,占66.6%;70例患者表现为病灶延迟强化,占83.33%;54例有肝门区及腹腔淋巴结转移,占64.29%。结论①肝内周围型胆管细胞癌的临床表现缺乏特异性,然而,华支睾吸虫肝病感染者中肝内周围型胆管细胞癌的发生率较高。②而CT检查肝内周围型胆管细胞癌的表现有一定的特异性,通过这些特征,很容易的对此病进行诊断。③肝内周围型胆管细胞癌患者进行CT检查时应常规进行增强扫描同时行延时扫描。
Objective To study the imaging findings and the corresponding diagnosis of peripheral cholangiocarcinoma using CT. Methods 84 cases of peripheral cholangiocarcinoma diagnosed and treated in our hospital from April 2010 to October 2012 were selected for CT imaging examination. Results The CT findings showed that the lesions of the 50 patients were located in the right lobe of the liver, accounting for 59.52%. The lesions of 58 patients were cystic or polycystic, accounting for 69.6% of the lesions. The lesions of the 60 patients showed borderline pruritus (71.43%). In 56 cases, the lesions around the bile ducts dilated, accounting for 66.6%. 70 cases showed delayed enhancement of the lesions, accounting for 83.33%; 54 cases had hilar and abdominal lymph node metastases, accounting for 64.29%. Conclusion ① The clinical manifestation of intrahepatic peripheral cholangiocarcinoma is not specific. However, the incidence of intrahepatic cholangiocarcinoma in Clonorchis sinensis is high. ② CT examination of the performance of intrahepatic cholangiocarcinoma has a certain specificity, through these characteristics, it is easy to diagnose the disease. ③ patients with intrahepatic peripheral cholangiocarcinoma CT scan should be performed routinely enhanced scan at the same time delayed scan.
