Retro-aortic Left Renal Vein and Hypertension

Retro aortic left renal vein (RALRV) anomaly is a relatively uncommon condition which leads to left renal vein hypertension (LRVH) syndrome, otherwise called as Nutcracker syndrome. In this paper, we report the case study of a patient who had labile hypertension and left sided varicocoele, but no other clinical features of RALRV anomaly. In cases of labile hypertension, investigations are directed towards detection of adrenal pathology. However, after observing this case, we would like to emphasize the relevance of including RALRV in the differential diagnosis of labile hypertension. For this purpose, a CT Scan of Abdomen, is of great value because a simultaneous detection of adrenal pathology as well as RALRV anomaly is possible. This would spare many unwanted investigations and make early and proper diagnosis feasible.
