The only abnormal finding in routine diagnostic investigation for ED consisted of congenital penoscrotal cavernous hemangioma (Figure 1a). As a vascular cause of the symptom was suspected, we performed MRI angiography after intracavernosal application of 10 mug alprostadil (Figure 1b): a substantial arteriovenous malformation showed symmetrical draining towards the internal iliac veins. Therefore, we recommended selective percutaneous retrograde venoocclusive therapy, which was performed successfully in two sessions (Figure 1c).

Values for all useable lying and standing intervals were compared by applying a paired samples t-test (Figure 2); p<0.05 was considered significant.
