Abstract
Three biliary cystadenomas are reported. Two occurred in the left lobe of the liver and the third involved the right lobe and the medial segment of the left lobe. All three patients had gray scale sonography of the liver and two underwent hepatic angiography. The sonographic features were similar to those of cystadenoma of the ovary or pancreas, that is, multilocular cystic lesions with septations and papillary projections. Angiographically the lesions were hypovascular with a faint rim of contrast-material accumulation in the wall and septa of the mass.
