Ultrasound (US) is primary imaging modality for assessment of plaque and erectile dysfunction in patients with Peyronie disease to guide medical vs. surgical treatment planning; however, magnetic resonance imaging (MRI) and computed tomography (CT) can be used in the pretreatment and post treatment setting as well. After reviewing this exhibit the learner will: (1) Understand the pathophysiology of acute and chronic fibrosing Peyronie disease. (2) Recognize US findings of Peyronie plaques and US Doppler features of erectile dysfunction. (3) Describe role of noncontrast CT for calcified Peyronie plaques. (4) Determine when to use imaging after penile surgery. (5) Recognize normal and abnormal imaging findings of penile implants.

Pre-treatment imaging with case examples (1) Penile US grayscale: plaque Doppler: erectile function (2) CT and MR when to use, typical protocols, findings (C) Surgical treatment options (1) tunical plication vs. plaque incision/excision +/- grafting (2) role of penile prothesis (D) Post operative imaging (1) typical findings complications
