    Axial and Coronal MRI
     

    Infiltrative soft tissue of intermediate signal, distorting the architecture of the penile shaft.

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

    Low T2 signal within the right corpus cavernosum, indicating infiltrative disease.

    Multiple bilateral metastatic lesions in the lungs with an SUV max of 10.5.

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: PET-CT; Procedure: Diagnostic procedure; Special Focus: Metastases;

    Diffuse metabolic activity within the infiltrative penile mass, SUV max of 14.3.

    Histology of penile biopsy

    Penile biopsy showing diffuse replacement by poorly differentiated carcinoma (Haematoxylin and eosin x100) and diffuse necrosis, suggestive of poorly differentiated prostate adenocarcinoma.
