The left renal artery has a saccular aneurysm at the renal pelvis. There is mural calcification and irregular soft plaque. The aneurysm measures 2.5 x 2.0 x 2.75 cm (width x anteroposterior x craniocaudal). There is extrinsic compression of the left renal pelvicalyceal system with moderate hydronephrosis and cortical thinning especially of the upper and mid poles.
The right kidney is normal in size and polarity with normal uptake and excretion of contrast. There is no nephroureterolithiasis bilaterally. The left renal vein runs inferiorly to join the proximal IVC/right common iliac vein at the level of the aortic bifurcation (type IV, renal vein anomaly).
The appendix is normal. There is a previous hysterectomy; CT imaging is otherwise unremarkable.
