    Sagittal T2-weighted image (a) shows solid-appearing ovoid mass centered in the postbulbar corpus spongiosum, with upstream urethral dilatation.

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

    On sagittal (b) and axial (c) T2-weighted images, the tumour shows hypointense signal compared to the corpus spongiosum, with evident central urethral lumen in its distal portion.

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

    The tumour appears solid, moderately hyperintense on fat-suppressed STIR image (d).

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

    On sagittal (e) and axial (f, g) T1-weighted images the tumour shows solid, intermediate signal intensity.

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: MR;

    On sagittal (e) and axial (f, g) T1-weighted images the tumour shows solid, intermediate signal intensity. No suspicious inguinal adenopathies are present.

    Follow-up MRI after surgical penectomy
     

    Sagittal (a), coronal (b) and axial (c) T2-weighted, axial T1-weighted (d) images show normal post-penectomy status.

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

    Appearance of two enlarged left inguinal lymphadenopathies showing abnormal signal intensity, consistent with metachronous nodal metastases.
