title: MRI of multiple biliary hamartomas.
abstract: Multiple biliary hamartomas (MBH) are uncommon benign malformations of the bile ducts. A case of MBH simulating liver metastases is reported, the diagnosis having been ascertained by US-guided biopsy. US and CT showed multiple hepatic nodules scattering in both lobes of the liver. Angiography showed small hypovascular lesions as well as hypervascular nodules. Only two cases with MRI studies have previously been reported. In this case, the finding was of hepatic cysts containing intermediate signal mural nodules. Demonstrating hepatic cysts with mural nodules on imaging will considerably increase the accuracy of diagnosis.
