Pediatric testicular tumors: Evaluation with gray-scale and color Doppler US

PURPOSE: To evaluate the appearance of testicular neoplasms in pediatric patients at examination with gray-scale and color Doppler ultrasonography (US). MATERIALS AND METHODS: Gray-scale and color Doppler US were performed in seven patients aged 8 1/2 months to 17 years 6 months (mean age, 7.8 years) with testicular neoplasms proved at histologic examination. Gray-scale images were evaluated for echogenicity and presence of testicular masses; color Doppler US was used to assess the presence and distribution of color flow. RESULTS: Gray-scale US showed enlargement of the affected testis in all patients. Testicular echogenicity was normal in four prepubertal patients; discrete masses were seen in all three postpubertal patients. The gray-scale findings correlated with patient age. Color Doppler US demonstrated increased blood flow in six of seven testicular neoplasms. Three of the four patients with normal gray-scale echogenicity had diffuse hypervascularity and one had a focal hypervascular mass on color Doppler scans. CONCLUSION: Color Doppler US is more helpful than gray-scale US in identification of testicular tumor.
