At autopsy, a case of peliosis hepatis was found incidentally in a patient receiving diethylstilbestrol for seven years for prostate cancer. We stueied a direct correlation between ultrasonography (US) and histology of peliosis hepatis using the formalin-fixed autopsied liver.<BR>The US of peliosis hepatis was not hyperechoic image, but iso- and hypoechoic heterogeneous echo texture. Histologically, peliosis hepatis was multiple small cystic blood-filled spaces without endothelial lining. Communication of the cystic spaces with sinusoids were evident. These histological architectures were different from cavernous hemangioma, which shows hyperechoic image. Main cause of non-hyperechoic image of peliosis hepatis may be due to above described histological architectures.
