A man in his 20s was injured when a hard ball moving at roughly 100 kilometers per hour struck his left scrotum directly during a field hockey game. The initial diagnosis at another hospital was testicular contusion, and the patient was referred to our department on the third day post-injury for follow-up evaluation. However, based on the physical and ultrasound findings, we were unable to definitively diagnose his injury. Subsequently, we performed contrast-enhanced magnetic resonance imaging, which showed findings suggestive of tunica albuginea rupture. During emergency surgery, a tunica albuginea rupture was confirmed through scrotal exploration and visual inspection. The rupture was repaired, and orchiopexy was performed. Magnetic resonance imaging is effective in diagnosing testicular rupture when it cannot be identified through other medical assessments.
