Fournier's gangrene is a urologic emergency secondary to a necrotizing soft tissue infection. Fournier's gangrene is characterized by severe pain and features of Fournier's gangrene may include edema, blisters and bullae, crepitus, subcutaneous gas, and systemic symptoms. Risk factors include male gender, alcohol abuse, immunocompromised state, uncontrolled diabetes mellitus, obesity, and malignancy. The diagnosis is made clinically but is often supported by radiography, ultrasound, computed tomography, and magnetic resonance imaging. Treatment consists of emergent hospitalization and surgery to debride the necrotic tissues. Morbidity and mortality for Fournier's gangrene are very high if left untreated. Early surgical intervention is key to the successful treatment of Fournier's gangrene. This case report presents a case of Fournier's gangrene mimicking acute epididymitis and highlights the importance of a thorough physical examination with high clinical suspicion for Fournier's gangrene.
