Overview

Overview

On ultrasound, Fournier gangrene is characterized by:[1][2] Thickened scrotal wall, echogenic gas foci in scrotum pathognomonic (seen as dirty shadowing), testes and epididymi spared (due to their separate blood supply), reactive unilateral or bilateral hydroceles are present, differentiate Fournier gangrene from inguinoscrotal incarcerated hernia (In inguinoscrotal incarcerated hernia gas is observed in the obstructed bowel lumen, away from the scrotal wall).
