title: Perirenal extravasation of urographic contrast medium demonstrated by computed tomography.
abstract: Two cases of spontaneous perirenal extravasation of urographic contrast medium are presented. Both were secondary to ureteral obstruction by tumor. Computed tomography demonstrated the presumed route by which contrast material reached the perirenal space as opposed to the more common peripelvic area.
