High-flow priapism due to bilateral cavernous artery fistulas treated by unilateral embolization: A case report

Figure 1 Color Doppler ultrasonography, computed tomography angiography, and magnetic resonance imaging of the patient. A and B: Color Doppler ultrasonography revealed bilateral cavernous artery fistulas and bilateral pseudoaneurysms complicated by an interaneurysmal fistula (the width of the right fistula was approximately 0.6 cm); C: Contrast-enhanced computed tomography scanning (arterial phase) revealed bilateral cavernous artery pseudoaneurysms; D and E: Maximum intensity projection images revealed pelvic and penile artery anatomy; F: Arterial flow was characterized by a high flow with high resistance and irregular biphasic bidirectional flow (peak arterial flow: 162 cm/s); G: Axial T1-weighted imaging; H: Diffusion weighted imaging; I: Contrast-enhanced T1-weighted imaging (arterial phase) revealed bilateral cavernous pseudoaneurysms with cavernous septum injuries.
