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.

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 approaches used in multidisciplinary management.

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 · Intraductal papillary neoplasm of the bile duct (IPNB) is a rare variant of bile duct tumors characterized by papillary growth within the bile duct lumen and is regarded as a biliary counterpart of intraductal papillary mucinous neoplasm of the pancreas. IPNBs display a spectrum of premalignant lesion towards invasive cholangiocarcinoma.

ipnb主要应与以下疾病鉴别：①胆管癌，主要表现为胆管壁增厚；而ipnb表现为胆管内壁附着的乳头状结节，胆管壁本身较光滑、完整。 胆管癌较IPNB更易侵犯周围组织，并出现淋巴结转移、肝内转移等征象。

Background: Intraductal papillary neoplasms of the bile duct (IPNB) are rare precancerous lesions with implications for the development of cholangiocarcinoma (CCA). Recognizing IPNB and managing its recurrence pose challenges in clinical practice. We present two cases.

2023年8月11日 · Intraductal papillary neoplasm of the bile duct (IPNB) is a rare condition that might cause bile duct cancer. It has not been studied as much as intraductal papillary mucinous neoplasm, a similar disease of the pancreas.

2021年2月1日 · Intraductal papillary neoplasm of the bile duct (IPNB) is a rare bile duct epithelial tumor, accounting for 10-15% of bile duct tumors [1]. IPNB is considered as the biliary counterpart of the intraductal mucinous papillary neoplasm of the pancreas [2].

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 ...

2021年3月1日 · According to the definition contained in the 5th edition of the World Health Organization (WHO) Classification of Digestive System Tumors (2019), intraductal papillary neoplasm of the bile ducts (IPNB) is a pre-invasive, intraductal growing tumor originating from the bile epithelium, consisting of papillary and villous structures [14].
