Sonographic appearance of the epididymis in pediatric testicular torsion.

Objective: The purpose of this study was to determine the frequency of an enlarged epididymis in pediatric patients with testicular torsion and to determine whether an altered epididymis might be a helpful ancillary sonographic sign of testicular torsion.

Materials And Methods: The sonograms of 50 pediatric patients (age range, neonate-17 years) with testicular torsion were retrospectively reviewed for the size, appearance, and blood flow of the epididymis. Medical records were reviewed for surgical and pathologic findings and to determine whether testicular salvage had been possible.

Color Doppler sonography and scintigraphy of the testis: a prospective, comparative analysis in children with acute scrotal pain.

Objective: To compare testicular color Doppler sonography with testicular scintigraphy in differentiating between surgical and nonsurgical conditions of the pediatric testis, and to evaluate the role of testicular color Doppler sonography in the pediatric population.

Materials And Methods: Forty-six children (age range, 1 day to 18 years; median age, 11 years) with acute scrotal pain were evaluated with both scintigraphy and color Doppler sonography by two separate groups of radiologists who had no knowledge of the results of the other modality. The final radiologic diagnosis was classified as a surgical condition, nonsurgical condition, or indeterminate and was compared with the patient's surgical diagnosis or clinical diagnosis, which was established by response to treatment and follow-up.
