摘　　要：目的分析胆管内黏液性乳头状瘤(IPMN-B)的超声表现,探讨超声对其诊断的价值。方法回顾性分析2016年1月至2023年3月经手术病理证实的8例IPMN-B患者的超声表现及临床资料。结果8例IPMN-B患者均出现与梗阻因素不相称的胆管扩张,5例局限于肝左叶,3例累及肝左右叶,6例胆总管扩张,3例呈动脉瘤样扩张。6例扩张胆管内可见等、高回声肿瘤,边界清晰,可见少许彩色血流。4例伴有肝内胆管结石。结论IPMN-B的超声表现有一定的特征性,当出现与梗阻因素不相称的胆管扩张,尤其是上游及下游胆管均扩张,且扩张胆管内见乳头状、扁平状结节,边界清晰,可见少许彩色血流时需要考虑IPMN-B的诊断。Objective To analyze the ultrasonic manifestations of intrabiliary mucinous papilloma(IPMN-B)and explore the value of ultrasound in its diagnosis.Methods The ultrasonographic features and clinical data of 8 cases of IPMN-B confirmed by surgery were analyzed retrospectively.Results All 8 cases of IPMN-B had bile duct dilatation not commensurate with obstructive factors,5 cases were confined to the left lobe of the liver,3 cases involved the left and right lobes of the liver,6 cases showed common bile duct dilatation,and 3 cases showed aneurysmal dilation.In 6 cases of dilated bile duct,there were isoechoic papillary flat tumors with clear boundaries and a small amount of color blood flow.Four cases were complicated with intrahepatic bile duct stones.Conclusion The ultrasonic manifestations of IPMN-B have certain characteristics.When bile duct dilatation was not commensurate with obstructive factors,especially upstream and downstream bile ducts are dilated,papillary and flat nodules with clear boundaries are seen in the dilated bile duct and a little color blood flow that should be considered for the diagnosis of IPMN-B.
