In a normal man (A), the cavernosogram shows opacification of the erect corpora cavernosa and nonvisualization of penile veins. In (B), the patient has a large leak through both superficial dorsal veins (arrows) to the saphenous veins (arrowheads). Film (C) shows abnormal venous drainage via the cavernous veins (solid arrow) into the preprostatic plexus (open arrow) and the internal pudendal veins (arrowhead).
