Scrotal "arteriocele" from iliac artery occlusion.

A case is described in which a testicular artery, pulsatile and palpable in the scrotum, provided a major collateral for an obstructed iliac artery. The testicular artery was probably spared from occlusion because it originated from a renal artery. Following surgical relief of the iliac obstruction, the testicular artery reverted to normal caliber and was no longer palpable in the scrotum.
