ABSTRACT

A 24-yr-old male who experienced fleeting episodes of left scrotal pain since the age of 13 had an ultrasound that suggested testicular duplication on that side (triorchidism). Five months later he had acute left scrotal pain lasting for 12 hr. At that time routine scrotal scintigraphy revealed late torsion and an additional sitting view demonstrated triorchidism. Literature review indicates that in this rare condition there is an increased risk of torsion. In only two prior reports did an ultrasound examination suggest triorchidism preoperatively.
