Ultrasound of Testicular Torsion

Listen Later

In this radiology lecture, we review the ultrasound appearance of testicular torsion through three unique cases.

Key teaching points include:

  • Torsion occurs when spermatic cord twists and cuts off blood supply to the testis.
  • Bell-clapper deformity most common etiology: Abnormally high attachment of tunica vaginalis allowing spermatic cord rotation and testicular torsion (intravaginal).
  • Torsion has a bimodal distribution: First year of life (extravaginal), adolescents/young adults (intravaginal).
  • “Whirlpool” sign: Eddy swirl of coiled spermatic cord superior to testis, highly specific but less commonly seen than redundant spermatic cord.
  • Redundant spermatic cord AKA boggy pseudomass, torsion knot, epididymal-cord complex and should be avascular or only minimally vascular (unlike paratesticular neoplasm or acute epididymitis).
  • Testicles normally lie vertically, but horizontal or oblique (diagonal) lie suspicious for torsion.
  • Testicular enlargement, reactive hydrocele and scrotal skin thickening are secondary findings of torsion.
  • Marked testicular heterogeneity = Late torsion and nonviability/necrosis, more likely after 24 hours of symptoms.
  • Treatment: Detorsion and orchiopexy if salvageable, orchiectomy if not.
