Abstract：
Intraductal papillary neoplasm of the bile ducts is a rare tumor. Characteristic features include bile duct dilatation, cystic lesions with communication to the bile ducts, and intraluminal solid nodules arising from the bile duct wall. As in pancreatic intraductal papillary mucinous neoplasia, intestinal, pancreaticobiliary, gastric, and oncocytic types are described. Intraductal papillary neoplasm of the bile ducts has a high potential for malignancy, and patients should be surgically resected when possible. In this review, the complex imaging diagnosis is presented. The main focus is on contrast-enhanced ultrasound, an established method for many other indications whose potential on the biliary system should be better exploited. In the present article, typical contrast-enhanced ultrasound findings in intraductal papillary neoplasm of the bile ducts are demonstrated.
摘要：
胆管导管内乳头状肿瘤是一种罕见的肿瘤。特征包括胆管扩张，与胆管相通的囊性病变，和胆管壁产生的腔内实性结节。与胰腺导管内乳头状黏液性肿瘤一样，肠,胰胆管,胃,描述了嗜酸细胞类型。胆管导管内乳头状肿瘤具有很高的恶性可能性，患者应尽可能手术切除。在这次审查中,提出了复杂的影像学诊断。主要集中在超声造影,一种用于许多其他适应症的既定方法，这些适应症对胆道系统的潜力应得到更好的利用。在本文中,证实了胆管导管内乳头状肿瘤的典型超声造影表现。
