Preureteric vena cava is a rare congenital anomaly usually presenting clinically with hydronephrosis and an "S or fishhook" deformity of the ureter at the third or fourth lumbar vertebrae. Unusual presentations do occur and can lead to misdiagnoses. Herein such a case originally diagnosed as a ureteropelvic junction obstruction is presented and the embryology reviewed.
