The use of high-frequency ultrasound in the treatment of cystic, vascular, and solid non-neoplastic intratesticular masses is increasing. Cystic lesions examined include simple testicular cysts, tunica albuginea cysts, epidermoid cysts, tubular ectasia of rete testis, and intratesticular abscesses. Vascular lesions discussed include intratesticular varicocele and intratesticular arteriovenous malformation (AVM). Solid lesions studied include fibrous pseudotumor of testis, focal/segmental testicular infarct, fibrosis of testis, testicular hematoma, testicular hamartomas, congenital testicular adrenal rests, tuberculoma, and sarcoidosis. Gray scale and color flow Doppler sonography facilitate visualization of the benign characteristics of the lesions. Magnetic resonance imaging (MRI) can also help as a problem-solving modality in some cases.
