Aberrant vessels, although rare, may extrinsically compress ureter which on imaging may masquerade as retrocaval ureter. The exact cause of obstruction in such atypical cases can be confirmed intraoperatively. We are presenting a case which on basis of radiological features was diagnosed as a case of retrocaval ureter, however, intraoperatively it was found to be a case of ureteric obstruction due to an aberrant vessel. Thus, whenever on imaging an atypical feature of retrocaval ureter is found, differential diagnosis of aberrant vessels should also be kept in mind.
