Figure 2 (A-C): Circumcaval ureter with calculus in the proximal obstructed ureter. (A) IVU showing grade-4 hydronephrosis and an opacity adjacent to L3 vertebral pedicle (arrow). (B) Axial MRU section clearly showing the ureteric segment posterior to the IVC with a signal void of a calculus in that segment (arrow). (C) T2-turbo spin echo coronal thick slab MRU showing the calculus as a signal void (upper arrow) and the circumcaval course of the ureter (lower arrow)
