[A young man with a painful scrotum].

A 16-year-old male patient with no known medical history presented at the Emergency Department (ED) with a 2-day history of pain and swelling in his right hemiscrotum. He was diagnosed with non-bacterial epididymitis and discharged home with medical advice. Six days after being diagnosed, the pain and swelling worsened and he was seen by a general practitioner who concluded that the symptoms were attributable to the previously diagnosed epididymitis. No further investigations were performed. Two days later he again presented at the ED, at which time colour Doppler echography revealed a testicular torsion of probably two days old. As after operative detorsion the testis was found to be non-vital, an orchidectomy was performed. This case illustrates that the diagnosis of epididymitis should always be reviewed in patients in whom the scrotum once again becomes painful. Early recognition and treatment of torsio testis gives a better chance of keeping the testis and therefore fertility.
