    Sagittal (a) Grey-scale and (b) power Doppler sonographic images of the right testis depict the presence of a small, well circumscribed intratesticular mass (arrow). The lesion is mainly hypoechoic, with rich...

    DW MRI
     

    Transverse (a) DW MRI image and (b) the corresponding ADC map (b= 900 s/mm2). The lesion (arrow) appears hypointense and mainly isointense on DW images and ADC maps, respectively.

    (b) Time-signal intensity curves. The tumour depicts early, strong upstroke enhancement, followed by gradual washout of the contrast medium (blue). The normal contralateral testis shows moderate, gradual linear...
