Priapism, penile erection characterized as prolonged and devoid of sexual stimulation or excitement is a rare condition. It is critical to distinguish between low- and high-flow priapism, because the treatment algorithm differs markedly for these 2 conditions. The diagnosis is made clinically and confirmed with color Doppler ultrasonographic imaging (CDUS). We present a 21 year old men with high-flow priapism and left lateral congenital penile curvature. A duplex Winter shunt procedure was employed with corporeal irrigation of heparin solution and adrenalin solution instillation, but the priapism returned 12 hours after. Following several days slow instillation of phenilephrine or adrenaline solution accompanied by oral flutamide therapy resulted in complete detumescence. We used both CDUS and magnetic resonance imaging (MRI) before and after treatment of priapism. Although CDUS has been the primary modality for cross-sectional imaging of the penis, the superior soft-tissue contrast and spatial resolution afforded by MRI provide an opportunity to advance imaging evaluation of this organ.
