CT-IVU confirmed the right ureterohydronephrosis with an anteroposterior diameter of the renal pelvis of 15 mm (Figure 1).

A right internal iliac artery aneurysm was noted at the level of L4/L5 vertebra bodies measuring 6.7 x 6.0 x 6.05 cm (AP x trans x Sag) (Figure 2), and the right ureter was moderately dilated to the level of the right internal iliac aneurysm (Figure 3), which was possibly the cause of the obstruction.
Contrast-enhanced CT scan of the abdomen and pelvis, with coronal images showing a large contrast-filled structure in keeping with iliac artery aneurysm compressing and pushing the urinary bladder laterally.
