title: Hepatic bile duct hamartomas (von Meyenburg Complexes): MR and MR cholangiography findings.
abstract: Multiple bile duct hamartomas (MBDHs) of the liver, also known as von Meyenburg complexes, are easily confused with diffuse metastatic disease of the liver on US and CT. At present, histologic examination after tissue preevaluation is usually necessary for definite diagnosis. We report four cases in which the MR features, and especially the MR cholangiographic (MRC) findings, were highly suggestive for MBDH. Characteristic findings include multiple markedly hyperintense nodules on T2-weighted imaging, typically measuring <1.5 cm; no communication with the biliary tree; and irregular delineation of the lesions with no or slight rim enhancement following gadolinium administration.
