Learning objectives
A practical and imaging facilitated approach to biliary duct dilatation will be presented to distinguish obstructive causes such as choledocolithiasis,
intraductal papillary mucinous neoplasms of the bile ducts (IPMN-B) and cholangiocarcinoma,
and non-obstructive causes such as Caroli disease,
choledochal cyst,
and primary sclerosing cholangitis (PSC).
Learning ojectives are:
- To recognize that bile duct dilatation can be due to a myriad of benign and malignant etiologies,
where identification of diagnosis is key for timely diagnosis and management.
- To highlight the importance of developing a systematic and thorough approach to dilated bile ducts through recognition of key features,
such as presence of obstruction and/or stones,
location of dilatation,
type of pathology (i.e.
neoplastic,
inflammatory),
while avoiding pitfalls and mimics.
