The patient suffers from multiple biliary hamartomas (also known as von Meyenberg complexes).
A typical imaging finding of this rare, benign biliary tract malformation is the diverse presentation of the disease in different imaging modalities.
Sonography is reported to demonstrate multiple hypo- to hyperechoic liver lesions that cannot be clearly identified as cystic lesions. In contrast, CT shows multiple, small circumscribed hypodense (near water density) lesions throughout both lobes of the liver.1 In MRI, the lesions can be identified as hypointense in T1-weighted and hyperintense in T2-weighted, thus presenting the typical morphology of cystic lesions.2 There is no enhancement of contrast media, if administered. MRCP shows multiple hyperintense lesions ("starry sky" configuration).
Biliary hamartomas appear macroscopically as greyish white nodules, typically well defined but without true capsulation. Histological examination shows proliferation of bile ducts lined by normal cuboidal epithelium which is embedded in
