Testicular extravaginal torsion

Case contributed by Dr Paul Adamoli


At birth, the left testis shows increased volume and consistency. It was visible as a little dimple on the medial surface of the left thigh, probably as consequence of a localized ischaemia.

Patient Data

Age: Newborn
Gender: Male

Ultrasound - day 2 of life

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.

Case Discussion

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.
