2024年6月23日 · Intraductal papillary neoplasm of the bile duct (IPNBD) is a preinvasive biliary tree neoplasm considered to be a precursor of cholangiocarcinoma. Biliary papillary adenoma and non-invasive papillary carcinoma of the biliary tract were terms used to refer to localized low-grade and high-grade intraductal papillary neoplasm of the bile ducts 1.

Intraductal papillary neoplasm of the bile duct (IPNB) is a precursor to invasive carcinoma and is a distinct pathologic diagnosis. The purpose of this study was to evaluate imaging features of IPNB on cross-sectional imaging studies with histopathologic correlation.

Intraductal papillary neoplasm of the bile duct (IPNB), a pre-invasive neoplasm of the bile duct, is being established pathologically as a precursor lesion of invasive cholangiocarcinoma (CCA), and at the time of surgical resection, approximately half of IPNBs show stromal invasion (IPNB associated with invasive carcinoma).

2018年4月9日 · We outline the concept of intraductal papillary neoplasm of the bile duct (IPNB), discuss the morphologic features of IPNB and the differential diagnoses, and describe the radiologic app...

2024年5月15日 · Intraductal papillary neoplasm of the bile duct (IPNB) is a heterogeneous disease similar to intraductal papillary mucinous neoplasm of the pancreas. These lesions have been recognized as one of the three major precancerous lesions in the biliary tract since 2010.

2021年3月1日 · Intraductal papillary neoplasm of the bile duct (IPNB) is a rare bile duct epithelial tumour with very low incidence in the West and constitutes a precursor to the development of cholangiocarcinoma. The diagnosis and management of IPNB remains challenging.

2020年1月27日 · The intraductal neoplasms of the bile ducts are divided into those lesions that are a precursor to adenocarcinoma of the bile ducts, also referred to as preinvasive lesions, and the invasive tumors, which are cholangiocarcinomas of intraductal growing type. 1. World Health Organization, International Agency for Research on Cancer.

Intraductal papillary neoplasm of the bile duct (IPNB) is a variant of bile duct carcinoma that is characterized by intraductal growth and better outcomes compared with common cholangiocarcinoma. IPNBs are mainly found in patients from Far Eastern areas, where hepatolithiasis and clonorchiasis are endemic.

2014年5月18日 · IPNB is defined as a biliary epithelial tumor with exophytic nature exhibiting papillary mass within the bile duct lumen and with prominent intraductal growth pattern. IPNB can develop anywhere along the biliary tree, including both intrahepatic and extrahepatic bile ducts.

IPNB should be taken into consideration when intraductal mass or cystic-solid mass with bile duct dilation, or remarkable bile duct dilation without intraductal mass, are found on US. Intraductal mass length > 3.0 cm is more commonly found in malignant IPNB. …
