目的探讨临床少见的胆管内乳头状黏液性肿瘤的影像表现。方法结合文献分析2例经病理证实的胆管内乳头状黏液性肿瘤患者的CT、MRI表现特点。结果 2例在CT、MRI检查时均显示胆管扩张,但无确切肿块,ERCP显示胆管内有充盈缺损,内镜下十二指肠乳头处见黄绿色胶冻样黏液,病理诊断分别为腺体乳头状增生并黏液内癌细胞和乳头状腺瘤。结论影像学检查表现为胆管瘤样扩张,MRCP示扩张胆管内信号不均,其内可见有充盈缺损,内镜检查发现十二指肠乳头处黄绿色胶冻样黏液可提示胆管内乳头状黏液性肿瘤诊断,但最终诊断依赖于病理检查。
Objective To investigate the clinical manifestations of biliary papillary mucinous neoplasms. Methods Combined with the literature analysis of 2 cases of pathologically confirmed intraductal papillary mucinous tumors in patients with CT, MRI features. Results Two cases showed dilatation of the bile ducts on CT and MRI examinations but no definite lumps. ERCP showed filling defects in the bile ducts, and yellow-green jelly-like mucus was observed in the endoscopic duodenal papillae. The pathological diagnosis was glandular Papillary hyperplasia and mucinous carcinoma cells and papillary adenoma. Conclusions Radiographic examination showed cholangioedema-like dilatation. MRCP showed unequal intrahepatic bile duct signal, and filling defect was observed in it. Endoscopic examination revealed that yellow-green jelly-like mucus at the duodenal papilla could indicate biliary papillary mucus Tumor diagnosis, but the final diagnosis depends on the pathological examination.
