目的研究肝吸虫感染引起的肝外型胆管癌的CT特征。方法回顾性分析19经手术和病理证实,与肝吸虫感染相关的肝外型胆管癌的CT征象,包括肿瘤在肝外胆管生长部位、生长方式、形态、强化情况,对周围器官的侵犯,淋巴转移,胆管扩张情况。结果18例CT均准确发现和定位,发生在左右肝管或肝总管14例(77.8%),发生在胆总管上中段1例(5.6%),发生在胆总管下端或壶腹部3例(16.7%)。肿瘤生长方式呈腔内型14例(77.8%),肿块型2例(11.1%),浸润型2例(11.1%)。增强扫描后肿瘤相对于肝组织呈等密度10例(55.6%),呈高密度6例(33.39%),呈低密度2例(11.1%)。肝内胆管严重、均匀型扩张14例,中央型扩张3例,轻度扩张1例。男性多见(n=15,83·3%)。结论与肝吸虫相关的肝外型胆管癌多发生在肝外胆管近端三分之一,腔内生长多见,老年男性多见,而且较非肝吸虫性肝外型胆管癌更易发现。
Objective To study the CT features of extrahepatic cholangiocarcinoma caused by hepatic infection. Methods The CT features of liver extrahepatic cholangiocarcinoma, which were confirmed by surgery and pathology, were retrospectively analyzed, including the growth pattern, morphology, enhancement of the extrahepatic bile duct tumor, invasion of peripheral organs, lymphatic Transfer, bile duct dilatation. Results All 18 cases were accurately located and located in 14 cases (77.8%) of the right or left hepatic duct or common hepatic duct, 1 case (5.6%) in the middle common bile duct, 3 cases (16.7 %). There were 14 cases (77.8%) of intracavitary tumors, 2 cases (11.1%) of tumor mass and 2 infiltrative vessels (11.1%). Compared with the liver tissue, the tumor showed 10 cases (55.6%) of the same density with high density in 6 cases (33.39%) with low density in 2 cases (11.1%). Intrahepatic bile duct serious, uniform expansion in 14 cases, 3 cases of central expansion, mild expansion in 1 case. Men more common (n = 15,83.3%). Conclusion Extrahepatic cholangiocarcinoma associated with liver fluke mostly occurs in one third of the proximal end of the extrahepatic bile duct, which is more common in the cavity and more common in elderly men than in non-hepatic juvenile extrahepatic cholangiocarcinoma.
