In this pictorial essay the authors review the normal sonographic gray-scale and Doppler appearance of the pediatric scrotum with an emphasis on technique. The authors present an update on ultrasound diagnosis and outcomes in testicular torsion and differentiation from other acute scrotal processes, as well as sonographic imaging of testicular microlithiasis and uncommon or atypical scrotal masses including splenogonadal fusion, polyorchidism, meconium peritonitis and epidermoid cyst. Further, the authors discuss testicular neoplasms in the context of testicular microlithiasis.
