Bile duct hamartoma
A bile duct hamartoma or biliary hamartoma, is a benign tumour-like malformation of the liver.
They are classically associated with polycystic liver disease, as may be seen in the context of polycystic kidney disease, and represent a malformation of the liver plate.[1]

Diagnosis[edit | edit source]
At CT scans, bile duct hamartomas appear as small, well-defined hypo- or isoattenuating masses with little or no enhancement after contrast administration.[2] At MRI, they appear hypointense on T1-weighted images, iso- or slightly hyperintense on T2-weighted images, and hypointense after administration of gadolinium based contrast-agent.[2] On imaging, multiple hamartomas may look similar to metastases or microabscesses.
