Research Advances in Clinical and Imaging Characteristics of Intraductal Papillary Mucinous Neoplasm of the Bile Duct / 中国医学科学院学报

ABSTRACT

Understanding on the intraductal papillary mucinous neoplasm of the pancreas (IPMN-P) has dramatically improved in the past three decades. A new disease named intraductal papillary mucinous neoplasm of the bile duct (IPMN-B) reported in recent years shares several similar clinical features with IPMN-P. The clinical manifestations and imaging characteristics of IPMN-B have been gradually recognized. This review summarizes some of the typical cases reported since 2000 and find that clinical manifestations of IPMN-B include epigastric discomfort,biliary colic,jaundice,intermittent fever,sometimes without any symptoms; imaging triads for IPMN-B are mucobilia,dilated bile duct,and bile duct mural nodule.
