Fig. 2 Imaging of the primary seminoma and metastatic pattern.a T1-weighted magnetic resonance imaging (coronal view) showed right testicular enlargement with a mosaic pattern.b Contrast-enhanced CT revealed a mildly hyperdense nodular lesion in the right testis.c CT showed lymphatic spread from the testis via the spermatic cord to the para-aortic lymph node.
