• Acute symptomatic hydroceles are not benign, require workup

Testicular Diagnoses

• Scrotal cellulitis
• Epididymitis
• Fournier gangrene
• Hematocele
• Hydrocele
  • Hydrocele (peds)
• Indirect inguinal hernia
• Inguinal lymph node (Lymphadenitis)
• Orchitis
• Scrotal abscess
• Spermatocele
• Tinea cruris
• Testicular rupture
• Testicular torsion
• Testicular trauma
• Testicular tumor
• Torsion of testicular appendage
• Varicocele
• Pyocele
• Testicular malignancy

Evaluation

Scrotal ultrasound of a 10 cm large hydrocele, with anechoic (dark) fluid surrounding the testicle.

• +Transillumination
• Consider testicular ultrasound

Management

• None indicated

Disposition

• Referral to urologist
• Hydroceles that persisted >1 year or in patients >18 months should undergo ultrasonography to rule out tumor vs inflammatory etiology
