The sonographic findings at birth suggests extra-vaginal torsion in testes.
The presence of calcifications in the tunica albuginea is caused by a chronic torsion, dated average 8 weeks before the scan.The ultrasound scan taken one month later confirms a gonadal atrophy.
It is plausible that, torsion occurred at 30th week of pregnancy, just after the beginning of the descent of the testis in the inguinal canal.
