A sixty-eight-year-old black man with clinical Stage A1 (T1a) adenocar
cinoma of the prostate was found to have a tortuous and redundant left
external iliac artery directly overlying the superior aspect of the p
rostate gland. The location of this blood vessel precluded radical ret
ropubic prostatectomy. To our knowledge, this is the first reported ex
ample of this clinical situation. Computer-generated three-dimensional
imaging from the computed tomography scan allowed accurate assessment
of the vascular anomaly.
