A 33-week-old male infant of appropriate status for gestational age, was born vaginally to a 28-year-old gravida 2, para 2 Latino woman after the onset of premature labor. Birth weight was 1724 gm with Apgar scores of 7 at 1 minute and 8 at 5 minutes. The newborn was alert with spontaneous respirations, but had mild intercostal and subcostal retractions requiring external oxygen support. The rest of the examination was unremarkable except for a discolored firm mass, found within the right hemiscrotum, that did not transilluminate. The left testis was in a descended position but of appropriate size and consistency. A testicular ultrasound (Figure 1) demonstrated an enlarged hypoechoic right testicle, and Doppler flow analysis revealed decreased to absent arterial blood flow. Surgical exploration performed within 6 hours uncovered a torsive necrotic right testis. Orchiectomy and contralateral ochiopexy were performed. THE CASE IN CONTEXTTorsion of the testicle in the prenatal or postnatal period is a relatively rare event. 1 Since it's first description in 1897 by Taylor, 2 nearly 100 Figure 1 The right testicle is larger (13 mm vs 9.6 mm) in diameter and slightly more hypoechoic.
