title: Perinatal testicular torsion: preoperative radiological findings and the argument for urgent surgical exploration.
abstract: Perinatal testicular torsion is an infrequent event, the management of which has been controversial. Occurrence is rare, estimated at 1 in 7500 newborns (Kaplan, G. W., Silber, I.: Neonatal torsion--to pex or not? In: Urologic surgery in neonates and young infants. Edited by King, L.R. Philadelphia: W.B. Saunders Co., 1988; Chapter 20, pp. 386-395). The frequency of bilateral perinatal torsion is up to 22% (J Urol. 2005;174:1579). Here, we describe two cases of bilateral asynchronous perinatal torsion, in which the only presenting abnormality on exam after birth was a unilateral scrotal mass. These cases illustrate that contralateral perinatal torsion may be present even when physical exam findings suggest unilateral involvement.
