RETRO-AORTIC LEFT RENAL VEIN AS A CAUSE OF UNILATERAL DENSE PERSISTENT NEPHROGRAM
Unilateral Dense Persistent Nephrogram
Abstract
INTRODUCTION
Retention of administered intravenous contrast for a prolonged period is termed dense persistent Nephrogram. None of the previously mentioned differentials ever included Retro-aortic left renal vein (RLRV) as a cause of unilateral dense persistent nephrogram. First case of its kind is presented here which presented as diagnostic dilemma and eventually turned out to be a normal variant.
