Ultrasound evaluation of scrotum in pediatrics.

Scrotal abnormalities are difficult to assess using clinical criteria alone. Ultrasound provides an accurate means of demonstrating the scrotal contents so that appropriate therapy may be instituted. In a retrospective study, 119 ultrasound examinations of 96 patients (aged 4 days to 23 years) have been compared with the clinical diagnosis, surgical/pathologic findings, and other imaging modalities. The gamut of disease identified included congenital anomalies, neoplasm, trauma, torsion, varicocele, hydrocele, epididymo-orchitis, epididymal cyst/spermatocele, and post-radiation fibrosis. The ultrasound findings correlated well in 93/96 patients. In inconclusive cases, sequential imaging helps differentiate traumatic and inflammatory lesions from neoplastic processes.
