Fournier's Gangrene

First described by a Parisian venearologist, Fournier's gangrene is a necrotizing fascitis involving the genital, perianal and perineal regions. The infection leads to thrombosis of subcutaneous vessels resulting in gangrene of the overlying skin. Early recognition of this condition with prompt surgical debridement and early antibiotics are vital in successful treatment of this process. Ultrasound findings include thickening of the scrotal wall and soft tissues of the perineum with associated scattered foci of dirty shadowing indicating subcutaneous gas (Fig 11a, 11b). Care must be taken to accurately diagnose this condition as immediate surgical debridement is needed.
