An uncommon etiology of cholestatic jaundice: Intraductal mucinous papillary tumor of the bile duct

Intraductal papillary mucinous tumors (IPMT) are known to occur in the pancreas but rarely can occur in the bile ducts. These tumors secrete mucin that may form mucous plugs resulting in biliary stasis, biliary duct obstruction and dilation. We report a case of IPMT of the biliary tract that presented with fatigue and a persistent cholestatic pattern of liver enzyme elevation and required a high index of suspicion to make the final diagnosis. The early recognition and treatment of these tumors is important, as unlike other bile duct tumors, these have a good prognosis.
