Question
14 year-old male presents with right-sided testicular pain. What's the diagnosis?
Answer
Answer: Testicular torsion
- Most common pediatric cause of testicular pain; Occurs in 1 in 4,000 males less than 25 years-old
- Sudden and severe pain with diffuse testicular swelling and tenderness; right side is affected more than the left.
- Most sensitive sign (90-100%) is absent or decreased cremaster reflex.
- Diagnosis is made by ultrasound demonstrating an enlarged testicle, increased echogenicity, and little to no Doppler flow (as seen above) compared to a testicle with normal flow (see below)
- Requires emergent urology consult for surgical detorsion and fixation of testis to prevent recurrence; testicular salvage rate is 90% within 6 hours of presentation as compared to 20% at 24-48 hours
- Manual detorsion should be attempted if urology consult is delayed.
