Posttraumatic "high-flow" priapism evaluation with color flow Doppler sonography.

Three cases of posttraumatic, high-flow arterial priapism are reported. In each, targeted color flow sonography was performed, demonstrating the site of intracavernosal arterial-sinusoidal fistula. Two of the three lesions could only be detected with the use of color Doppler sonography, emphasizing its role in the noninvasive diagnostic imaging work-up of this disorder.
