An Unexpected Delivery

Abstract

Background: Intraductal Papillary Mucinous Neoplasms of the Bile Duct (IPNBs) are rare biliary tumors. We present an unusual case with its management. Case Presentation: A 58-year-old man with a history of metastatic TCC presented with recurrent biliary abdominal pain and pruritus. Imaging revealed a dilated common biliary duct with a stone-like filling defect. ERCP revealed a grape-like polycystic mass, subsequently diagnosed as IPNB. Conclusion: IPNBs, though rare, should be considered in the differential for atypical biliary lesions. Timely diagnosis and management are essential due to their malignant potential.
