title: Bile-duct hamartomas presenting as multiple focal lesions on hepatic ultrasonography.
abstract: Multiple bile-duct hamartomas are usually diagnosed at autopsy as an incidental finding. We report a case of a 50-yr-old male in whom multiple bile-duct hamartomas were suspected in an abdominal ultrasonography and confirmed by an echo-guided needle liver biopsy. The ultrasonography disclosed multiple scattered hyperechoic lesions with a diameter of up to 1 cm, associated with some anechoic lesions of a larger size and a cystic appearance. Computed tomography demonstrated multiple hypodense lesions that were not modified by the administration of contrast. Bile-duct hamartomas should be included in the differential diagnosis of multiple focal hepatic lesions at ultrasonography or computed tomography.
