    Axial T1-weighted image

    Axial T1-weighted image demonstrates the antero-lateral lesion of intermediate signal intensity (white arrow) – slightly higher than muscle – with a hyperintense spot (black arrow) that may correspond to melanin...

    Sagittal T2-weighted image

    Sagittal T2-weighted image shows intermediate/high signal intensity lesion arising from the anterior wall of the lower third of the vagina (arrow). Note that the intravaginal contrast (ultrasound gel) helps to depict...

  • Figure 3
    Axial T2-weighted image

    Axial T2-weighted image shows that the vaginal lesion has slightly high signal intensity (white arrow) and that the urethra wall at this level is preserved, with no signs of invasion (black arrow).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Staging; Special Focus: Neoplasia;
     
     
  • Figure 4
    Axial T2-weighted image

    Axial T2-weighted image demonstrates invasion of the urethra by the vaginal tumour at a lower level than previous picture (white arrow).

  • Figure 5
    Sagittal fat-suppressed T1- weighted image + gadolinium

    Sagittal fat-suppressed T1- weighted image after the administration of gadolinium shows the homogeneous enhancement of the vaginal lesion (arrow).

     
    Area of Interest: Genital / Reproductive system female; Imaging Technique: MR; Procedure: Staging; Special Focus: Neoplasia;
     
     
  • Figure 6
    Axial diffusion-weighted image

    Axial diffusion-weighted image (b = 600 sec/mm2) shows the mass (arrow) with bright signal intensity.

  • Figure 7
    Sagittal sections of the gross specimen

    Two sagittal sections of the gross specimen of the lower third of the vagina. A polypoid pigmented tumour (arrow) is observed in the anterior wall of the vagina.

Axial T1-weighted image demonstrates the antero-lateral lesion of intermediate signal intensity (white arrow) – slightly higher than muscle – with a hyperintense spot (black arrow) that may correspond to melanin or haemorrhage (methemoglobin).
 
Sagittal T2-weighted image shows intermediate/high signal intensity lesion arising from the anterior wall of the lower third of the vagina (arrow). Note that the intravaginal contrast (ultrasound gel) helps to depict the lesion.
