  • Figure 1
    Axial T1 TSE

    Axial TSE T1-weighted image shows a large mass replacing the prostate gland and extending into the left obturator muscle with homogeneous low signal intensity extending to the left obturator internus muscle.

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    Axial and sagittal T2 FSE
     

    Axial TSE T2-weighted image shows a heterogeneous high signal intensity multinodular mass with irregular margins, disrupting the prostate capsule and extending into the pelvic musculature on the left.

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Axial TSE T2-weighted image shows bulky nodular loco-regional adenopathy.

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    In sagittal TSE T2 plane the relative position of the tumour and adenopathy is better depicted.

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Axial 3D dynamic contrast-enhanced MR images
     

    Axial 3D dynamic contrast-enhanced MR images at 0 s.

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Axial 3D dynamic contrast-enhanced MR images at early enhancement phase show heterogeneous enhancing mass containing necrotic areas in central gland.

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Axial 3D dynamic contrast-enhanced MR images at late phase of enhancement show heterogeneous enhancing mass containing non-enhanced necrotic areas in central gland.

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 4
    Axial diffusion-weighted images
     

    Axial diffusion-weighted image (b=0) showing heterogeneous tumoural mass.

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Axial diffusion-weighted image (b1000) showing mass with marked high signal intensity.

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Axial ADC map revealing correspondent low signal tumour, related to marked restriction to water diffusion.
