  • Figure 1
    Axial TSE-T1 weighted image

    Large homogeneous hypointense lesion (asterisk) which contain a well-circumscribed nodule of intermediate signal intensity (arrows).

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Neoplasia;
     
     
  • Figure 2
    Axial TSE-T2-weighted image

    Large homogeneous hyperintense lesion (asterisks) with hypointense rim (arrowheads). The well-circumscribed nodule appears hyperintense with thick hypointense septa and hypointense capsule. A hypointense nodule in the...

  • Figure 3
    Axial TSE-T1 images obtained after intravenous gadolinium administration

    Gadolinium enhanced image demonstrates heterogeneous enhancement of the right testis and peripheral (arrowheads) and heterogenous (arrows) enhancement of the left testicular mass.

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Neoplasia;
     
     
  • Figure 4
    Haematoxylin-eosin stain x20 and x40

    Large cells separated by fibrous septa (large arrow) infiltrated by lymphocytes (small arrow). Tumour cells are uniform, with clear cytoplasm, outlined cell membranes, a large centrally located nucleus and clumped...

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: PACS; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 5
    Cut surface photograph of resected left testis

    Whitish-grey tumour (arrowheads) adjacent to a large cystic cavity replacing most of the testis (arrows).

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: PACS; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 6
    Photomicrograph of histologic section (Haematoxylin-eosin x40)

    Photomicrograph shows medium-size cells (small arrow), together with small lymphocyte-like cells (large arrow) and giant cells (arrowhead). The chromatin is dense in small cells and filamentous in the intermediate and...

Large homogeneous hyperintense lesion (asterisks) with hypointense rim (arrowheads). The well-circumscribed nodule appears hyperintense with thick hypointense septa and hypointense capsule. A hypointense nodule in the right testis also can be seen (arrows).
 
Gadolinium enhanced image demonstrates heterogeneous enhancement of the right testis and peripheral (arrowheads) and heterogenous (arrows) enhancement of the left testicular mass.
 
Large cells separated by fibrous septa (large arrow) infiltrated by lymphocytes (small arrow). Tumour cells are uniform, with clear cytoplasm, outlined cell membranes, a large centrally located nucleus and clumped chromatin pattern with nucleolus (arrowheads).
