Despite an expanding number of studies on intraductal papillary neoplasm of the bile duct (IPNB), distant metastasis remains unexplained especially in cases of carcinoma in situ . In the present study, we report a rare and interesting case of IPNB without invasive components that later metastasized to lungs and brain.
