[The contribution of imagery in the early diagnosis of Fournier's gangrene]. / Apport de l'imagerie dans le diagnostic précoce de la gangrène de Fournier.

Scrotal ultrasonography, completed by MRI, allowed the early diagnosis of a case of Fournier's gangrene, before the appearance of subcutaneous crepitation allowing rapid treatment adapted to the extent of necrosis. Ultrasonography is recommended in the assessment of inflammatory disease of the scrotum and/or perineum. MRI is able to refine the ultrasonographic data, and define the extent of gangrene as well as its starting point.
