Erectile dysfunction (ED) affects up to 50% of men to some degree and has a variety of physiologic and psychologic causes, but many patients do not seek specialist treatment. One cause of ED is Peyronie disease (PD) defined by the presence of fibrotic plaques in the tunica albuginea which cause painful penile contractures. While diagnosing PD relies on clinical history and a focused history and physical exam, adding imaging studies can identify nonpalpable plaques and any underlying vasculogenic ED to tailor the extent of surgical treatment and determine when implantable penile prostheses are beneficial. After briefly reviewing penile anatomy, erectile function, and the clinical features of PD, this paper describes the imaging findings of vasculogenic ED on Doppler ultrasound (US), followed by the imaging appearance of PD on US, computed tomography (CT), and magnetic resonance imaging (MRI) to increase recognition of this disease and show how imaging can be used as a problem-solving tool for treatment planning and evaluating post-surgical complications, especially malfunctioning implanted devices. By increasing the understanding of how imaging can be used for patients with PD with or without vasculogenic ED before and after treatment, radiologists and urologists can collaborate on patient management.
