Abstract

A persistent nephrogram sign is described as the prolonged renal cortical retention of iodine-based contrast media and striking parenchymal enhancement in the kidneys on performing unenhanced computed tomography. It can be seen after the administration of iodine-based contrast media in patients with contrast-induced nephropathy or renal insufficiency. This case report aimed to describe the persistent nephrogram sign and inform clinicians about contrastinduced nephropathy in light of the current medical literature.

Keywords: Iodine-based contrast medium, computed tomography, kidney, nephrogram sign, acute kidney failure.
