title: Periportal sinusoidal dilatation associated with pregnancy.
abstract: Periportal sinusoidal dilatation is an hepatic vascular lesion previously reported solely as a complication of oral contraceptive therapy. We report a case occurring during pregnancy and describe the angiographic appearance and pathologic findings. Peliosis hepatis is the main consideration in the differential diagnosis--the features distinguishing of these hepatic lesions are presented.
