Y1 - 2014 N1 - T2 - Strange and Schafermeyer's Pediatric Emergency Medicine, 4e AB - Acute scrotal pain is usually caused by testicular torsion, epididymitis, or torsion of the appendix testis.Epididymitis is often caused by viral infections; however, bacterial urinary tract infections must be evaluated for in young children and sexually transmitted disease in adolescents.Persistent scrotal swelling and a “bag of worms” appearance indicates possible obstruction from tumor.Priapism can be divided into two mechanisms: low-flow or ischemic as in sickle cell vaso-occlusion and high-flow or engorgement.
