[A Case of Prenatal Testicular Torsion]

We report a prenatal case of neonatal testicular torsion. A 0-day-old boy with left scrotal swelling from the time of birth was referred to us. The physical examination revealed left intrascrotal hard mass. The ultrasonography with doppler color flow showed heterogeneous parenchymal echogenicity and the lack of blood flow to the affected testis. Testicular torsion was suspected and emergent surgical exploration was performed. The left testis was necrotic with extravaginal torsion of the spermatic cord. Left high orchiectomy was performed, considering the possibility of inguinal hernia. The histopathological examination confirmed the necrosis of the left testis.
