A 10-year-old man presented with acute right scrotal pain of 20 hours’ duration. He denied fever, vomiting and history of trauma. The scrotum showed no swelling or erythema, and the cremasteric reflex was normal. Both testes demonstrated normal vertical lie and softness on palpation. A tender area of subtle, blue discoloration was observed near the upper pole of the right testis that moved when the testis was manipulated (figure 1, online supplementary video). Both testes and the epididymal blood flow were normal on ultrasound.
