An abnormality in the left hemiscrotum can be seen on the most caudal aspect of both axial and coronal reconstructions.

Testicular ultrasound


US reveals a somewhat heterogenous low echogenicity mass within the left testicle which is enlarged (5.6 cm). The testicle demonstrates normal blood flow.
