胆管内肿瘤伴腔内息肉样生长很少见,其放射学征象更少见。作者回顾了12年来196例胆管肿瘤的放射学资料,其中20例伴有腔内息肉状肿瘤生长,占10.2％。结合ERCP、PTC、US、CT,对胆管病变的诊断正确率可达到100％,血管造影为42％。腔内息肉样病变主要发生于总肝管靠近其分叉部位以及乏特氏壶腹附近。其组织学检查结果显示,7例胆管腺癌,4例壶腹部腺癌,2例壶腹部绒毛腺瘤,1例囊腺瘤,1例囊腺癌,1 例肝细胞癌,1例类癌和3例转移性肿瘤。
Biliary tumors with polypoid growth in the cavity are rare, and their radiological signs are less common. The authors reviewed the radiological data of 196 cases of bile duct tumors over the past 12 years, of which 20 cases were associated with intraluminal polypoid tumor growth, accounting for 10.2%. Combined with ERCP, PTC, US, and CT, the diagnostic accuracy of cholangiopathy can reach 100%, and angiography is 42%. The polypoid lesions in the cavity mainly occurred near the bifurcation of the total hepatic duct and near the ampulla of Vater. The histological examination showed 7 cases of bile duct adenocarcinoma, 4 cases of ampulla adenocarcinoma, 2 cases of ampulla chorioadenoma, 1 case of cystadenoma, 1 case of cystadenocarcinoma, 1 case of hepatocellular carcinoma, 1 case of carcinoid And 3 metastatic tumors.
