von Meyenburg complex

von Meyenburg complex - 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 and represent a malformation of the liver plate. In C T scan , 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.
