A bile duct hamartoma or biliary hamartoma, is a benign tumour-like malformation of the liver.
Contents
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.
Eponym
The eponymous terms (von Meyenburg complex, Meyenburg complex) are named for Hanns von Meyenburg.
Diagnosis
At CT scans, bile duct hamartomas appear as small, well-defined hypo- or isoattenuating masses with little or no enhancement after contrast administration. 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. On imaging, multiple hamartomas may look similar to metastases or microabscesses.
