(a) B-mode sonography of the left testis shows an intratesticular mass with concentric rings of alternating echogenicity with a more echogenic central core. (b) Color Doppler sonography shows the absence of a vascular signal within the mass and a more echogenic central core (arrowhead).

The lesion demonstrated an 'onion ring' appearance with an echogenic central target appearance and was avascular on color Doppler sonography (Figure 2, Video 1).

Ultrasonography of the right hemiscrotum shows a mild hydrocele and an extratesticular intrascrotal mass with concentric rings of alternating echogenicity. Note the hyperechogenic central core (arrowhead).
