  • Figure 1
    CT scan obtained at supraglottic and glottic level of the larynx.
     

    CT shows a thickening of the free margin of epiglottis, associated to ulceration of the valleculae.

     
    Area of Interest: unknown; Imaging Technique: CT scan obtained at supraglottic and glottic level of the larynx.;

    A diffuse, symmetric and bilateral enhancement of aryepiglottic folds is seen.

     
    Area of Interest: unknown; Imaging Technique: CT scan obtained at supraglottic and glottic level of the larynx.;

    CT scan shows diffuse, bilateral, symmetric thickening and enhancement of false vocal cords.

     
    Area of Interest: unknown; Imaging Technique: CT scan obtained at supraglottic and glottic level of the larynx.;

    Laryngeal cartilages are preserved.

     
    Area of Interest: unknown; Imaging Technique: CT scan obtained at supraglottic and glottic level of the larynx.;
     
     
  • Figure 2
    MRI obtained at supraglottic and glottic level of the larynx.
     

    T2-weighted MR image shows multiple lymphadenopathies on both internal jugular chains.

     
    Area of Interest: unknown; Imaging Technique: MRI obtained at supraglottic and glottic level of the larynx.;

    Sagittal contrast-enhanced T1-weighted MR image shows diffuse enhancement at the supraglottic and glottic level demonstrating the extent of the lesion.

     
    Area of Interest: unknown; Imaging Technique: MRI obtained at supraglottic and glottic level of the larynx.;
     
     
  • Figure 3
    Section through the aryepiglottic folds.
     

    On the plain T1-weighted MR axial view, the aryepiglottic folds are thickened.

     
    Area of Interest: unknown; Imaging Technique: Section through the aryepiglottic folds.;

    After Gadolinium enhancement (same level), a diffuse, symmetric and bilateral enhancement of aryepiglottic folds is evidenced.

     
    Area of Interest: unknown; Imaging Technique: Section through the aryepiglottic folds.;
     
     
  • Figure 4
    Section through the vocal cords.
     

    On the plain T1-weighted MR axial view, the left vocal cord and the anterior commissure are thickened

     
    Area of Interest: unknown; Imaging Technique: Section through the vocal cords.;

    After Gadolinium enhancement (same level), a diffuse, symmetric and bilateral enhancement of the true vocal cords is displayed.

  • Figure 5
    Photomicrograph.
     

    Low magnification shows the Langhans cells which appear with violet staining. This cells are typically observed in tuberculosis>

     
    Area of Interest: unknown; Imaging Technique: Photomicrograph.;

    At high magnification, the Langhans cells are better characterized.
