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 is the first line imaging modality if a patient presents with a testicular abnormality.[1]
- Seminomas usually appear as a homogeneous intratesticular mass of low echogenicity compared to normal testicular tissue.
- The mass is usually oval and well-defined in the absence of local invasion
- Ii is usually confined within the tunica albuginea, rarely extending to paratesticular structures.
- Internal blood flow is seen on color doppler imaging
- Cystic regions and calcifications are less common than in non-seminomatous germ cell tumors.
- Larger seminomas can have a heterogenous appearance.
