Figure a. Transverse CT scans obtained after administration of intravenous and oral contrast material. (a) CT scan obtained through the level of the kidneys shows bowel within the right renal fossa (arrow) because the right kidney is absent. Note the small amount of free fluid. (b, c) Large right-sided soft-tissue attenuation mass with some areas of peripheral enhancement superiorly (white arrow in b) and necrosis inferiorly (white arrow in c). Note compressed inferior vena cava (black arrow). (d) CT scan obtained through the bladder base shows a normal left seminal vesicle (arrow) with absence of the right seminal vesicle. (e) Absent right spermatic cord and normal left spermatic cord (arrow).
