Figure 1: Left testicular seminoma in a 27-year-old man. ( a ) Transverse T2-weighted image depicts relatively homogeneous left testicular mass, mainly hypointense when compared to the normally hyperintense right testicular parenchyma (asterisk). The neoplasm is seen extending to the paratesticular space (arrow). ( b ) Transverse ADC map (b = 900 s mm-2) shows marked hypointensity of the tumor (asterisk), when compared with the normally hypointense contralateral testis. The ADC values of the right testis were 0.98 × 10-3 mm2 s-1. ADC: apparent diffusion coefficient.
