Biliary hamartoma of the liver

Biliary hamartomas are rare benign lesions in the liver that are composed of small, disorganized clusters of dilated bile ducts or remnants (also known as von Meyenburg complexes). It is believed that they are congenital (from birth) and may be genetically transmitted. Biliary harmatomas have been associated with polycystic kidney disease and polycystic liver disease.
