Abstract:
Anomalies of the epididymis are most commonly associated with an undescended testis but also found occasionally in a normally descended testis. Our 11-year-old patient presented with an acute scrotum and Doppler ultrasound that suggested epididymitis. Painful symptoms required scrotal exploration with the finding of a torsion and infarction of the epididymis. The etiology of the torsion was an abnormal attachment of the epididymis to the testis. Torsion of the epididymis has not previously been reported.
