Overview

[Imaging study] is the first line imaging modality for seminoma. Findings of seminoma on ultraosund include a homogeneous intratesticular mass of low echogenicity compared to normal testicular tissue.

Ultrasound

Ultrasound may be helpful in the diagnosis of seminoma. Findings on an ultrasound diagnostic of seminoma include:[1]
