Asymmetry of the renal nephrograms on CT: significance of the unilateral prolonged cortical nephrogram.

B A Birnbaum1, M A Bosniak, A J Megibow.   

Abstract

The finding of asymmetry in the renal nephrograms as manifested by a unilateral prolonged cortical nephrogram on dynamic contrast-enhanced CT examinations signifies the presence of an abnormality of renal parenchymal perfusion and/or tubular transit. The differential diagnostic possibilities include stenosis or long-standing occlusion of the renal artery, renal vein thrombosis, and urinary tract obstruction.
