MRCP appearance of Obstructive Jaundice: A Report of 47 case and Literature Review
-
摘要: 目的总结梗阻性黄疸的MRCP表现,提高其诊断的准确性。方法回顾分析47例经手术和病理证实的梗阻性黄疸患者的MRCP表现。结果恶性梗阻性黄疸25例,其中肝门胆管癌6例,胆囊癌2例,胆总管腺癌4例,胰头癌、十二指肠腺癌各3例,胰头转移瘤7例。良性梗阻性黄疸22例,其中炎性梗阻3例,胆囊或胆总管结石伴炎症13例,术后瘢痕、胆总管囊肿、十二指肠息肉各2例。恶性梗阻性黄疸的典型MRCP表现为肝内胆管呈"藤蔓"征,胆管突然截断,断端圆钝形态不规则,呈偏心性或向心性狭窄或充盈缺损。良性梗阻性黄疸的MRCP表现为肝内胆管呈"枯树枝"征,胆总管逐渐变窄或其内形态规则的充盈缺损,断端锐利、平直或倒杯口状或圆锥状。结论MRCP是诊断良、恶性梗阻性黄疸的有效方法。Abstract: Objective To conclude the MRCP appearance of obstructive jaundice so that to improve the diagnosis of obstructive jaundice.Methods MRCP appearance of Obstructive Jaundice in 47 patients proved by surgery and pathology were analyzed retrospectively.Results Malignant obstructive jaundice (n=25) were as follows: hilar cholangiocarcinoma (n=6) , gallbladder carcinoma (n=2) common bile duct adenocarcinoma (n=4) pancreatic head carcinoma, duodenal adenocarcinoma 9 (n=3) respectively, pancreatic head metastasis (n=7) .Benign obstructive jaundice (n=22) were as follow: inflammatory obstruction (n=3) , gallstone or common bile duct stone associated with inflammation (n=13) , operational scar, common bile duct cyst, duodenal polyp (n=2) respectively.The topic MRCP appearance of malignant obstructive jaundice: the vine-sign for intrahepatic bile, abrupt interruption suddenly and the irregular edge for bile duct appear the prejudicial or centripetal site or filling-defect.The topic MRCP appearance of benign obstructive jaundice: the deadwood-sign for intrahepatic bile, tapering of the dilated bile duct or the regular filling-defect, a sharp and straight tip or the cup-mouse-sign orthe taper-sign.Conclusion MRCP was a effective way of diagnosis of benign and malignant obstructive jaundice.
