Pitfalls and Practical Challenges in Imaging of the Pediatric Scrotum.

Ultrasound is the modality of choice for evaluation of the pediatric scrotum, as it provides excellent image quality without the use of radiation, need for sedation/anesthesia, or use of contrast material and can be used for serial examination. Ultrasound of the scrotum has proven to be useful for assessment of a wide gamut of congenital, infectious, inflammatory, endocrine, neoplastic, and traumatic abnormalities in pediatric patients of all ages from the tiniest premature infant to a fully grown young adult. This review article presents a varied spectrum of conditions that may affect the pediatric scrotum, what the radiologist needs to know to meet the challenge of limiting the differential diagnosis, and how to avoid pitfalls when imaging the scrotum.
