Case 334: Intrabiliary Mucin Producing Neoplasia (IMPN)

Diagnostic Categories:

Clinical Presentation:

44 year old man with elevated alkaline phosphatase.

CT: Massive bile duct dilatation

Imaging Findings:

Massive bile duct dilatation is due to mucin production of the tumors, which are better seen on MR than CT.
