Enlarged epididymis with heterogeneous texture; hypoechoic areas may be present; increased blood flow.

Hypoechoic area within the testis with blood flow observed.

Enlarged testis appearing entirely hypoechoic.

Characterized by irregular contour and focal alteration in echogenicity.

Heterogeneous area that becomes hyperechoic as it ages; avascular.

Normal testis appearance < 4 hours; enlarged and hypoechoic 4-12 hours; heterogeneous after 24 hours; absence of flow.

Fluid-filled sac that may be anechoic but often contains low-level echoes; surrounds the testis.

Located in the head of the epididymis; may contain echoes or septations; smooth walls and posterior acoustic enhancement.

Usually small and anechoic; often indistinguishable from spermatocele without ultrasound; has posterior acoustic enhancement.

Tortuous, dilated veins that increase in size during Valsalva maneuver; color Doppler confirms venous flow.

Contains low-level echoes; may have septations and loculations.
