Definition

Cyst resulting from incomplete closure of the processus vaginalis

Benign condition, with no risk of progression to an infectious or neoplastic complication.

The processus vaginalis closes at both ends but remains patent in its middle portion, giving rise to a funicular sac with accumulation of peritoneal fluid within it (= cyst of the cord)

Always large

Clinical features

  • Swelling along the spermatic cord, above the testis
  • Cosmetic concern
  • Mobile with the cord
  • Painless, irreducible
  • Often transilluminates

Ultrasound

  • Not systematic
  • Performed in cases of diagnostic uncertainty (particularly with an inguinal hernia)
  • Anechoic lesion with posterior enhancement, thin-walled, intracanalicular, which may displace the testis within the scrotum

Management

Surgical management, not urgent

Watchful waiting in children under 2 years of age

Differential diagnosis

  • Epididymal cyst
  • Hydatid cyst of the spermatic cord
  • Incarcerated hernia
