Fournier's gangrene: CT findings

Fournier's gangrene is an uncommon gas-forming infection of the scrotum which if not recognized early and treated appropriately may be fatal. In three patients recently seen at our institution, computed tomography (CT) was instrumental in establishing the correct diagnosis and determining the extent of the infectious process prior to surgery. The imaging findings at CT and its differential diagnosis are illustrated. A brief review of the current theories of pathogenesis of this interesting entity is presented.
