Overview

Ultrasound

On ultrasound, Fournier gangrene is characterized by:

• 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)
