Core Tip
Core Tip: Intraductal papillary neoplasm of the bile duct (IPNB) is a rare disease of the bile duct. We report the management of a 67-year-old patient who was asymptomatic but diagnosed with IPNB during treatment of early gastric cancer. Multiple imaging modalities were required to successfully diagnose the patient with IPNB. After successful hepatic surgery the patient was discharged without complications. Asymptomatic presentation of IPNB is particularly complicated to diagnose, but aggressive surgical resection can result in satisfactory patient outcomes.
