Ultrasonography can be used to detect fluid or gas within the soft tissues. [64] Gas in the scrotal wall is the "sonographic hallmark" of Fournier gangrene. Air may be appreciated in perineal and/or perirectal areas. Scrotal wall edema may be seen. The testes and epididymides are usually normal.

Ultrasonography may reveal other causes of acute scrotal pain, including the following:

  • Intratesticular injury
  • Scrotal cellulitis
  • Epididymo-orchitis
  • Testicular torsion
  • Inguinal hernia
