Post-traumatic High-flow Priapism: Multidetector Computed Tomography Demonstration.

High-flow priapism due to pseudoaneurysm is a relatively rare urologic condition. Clear anatomic delineation of the number and origin of feeding vessels facilitates pre-embolization planning. Computed tomographic angiography can afford a three-dimensional display of the feeding vessels. We present a 26-year-old man with post-traumatic high-flow priapism, which is the first case studied with computed tomographic angiography.
