Intraductal Papillary Mucinous Neoplasm of the Bile Duct (IPMN‑B): A Rare and Diagnostically Challenging Entity

Key Points

Intraductal papillary mucinous neoplasm of the bile duct has a significant risk of invasive carcinoma.
Around 95% of other hepatic cystic lesions do not pose this level of risk, making diagnosis critical.
Observational analysis conducted to emphasize the need for early diagnosis and complete surgical resection of IPMN-B.
Identifying IPMN-B in patients with large cystic lesions highlights the need for thorough evaluation.

Abstract

Teaching point: Albeit rare, IPMN-B should be considered and excluded when encountering a large hepatic cystic lesion, especially in the setting of associated biliary dilatation, because in contrast to 95% of other hepatic cystic lesions, it has significant risk of harboring invasive carcinoma and therefore mandates early accurate diagnosis and complete surgical resection.
