Partial segmental thrombosis of the corpus cavernosum associated with recreational use of sildenafil

Partial segmental thrombosis of the corpus cavernosum (PSTCC) is a rare disease involving thrombosis at the proximal corpus cavernosum. We describe the case of a 39-year-old African American man presenting with right groin pain who was diagnosed with PSTCC. Classic sonographic, computed tomography (CT), and magnetic resonance imaging (MRI) features were present. After conservative treatment with systemic anticoagulation, he had no long-term adverse effects or erectile dysfunction. Although various risk factors for PSTCC have been reported, this is the first documented case associated with recreational use of a phosphodiesterase inhibitor.
