1. Serial axial contrast-enhanced CT images in an older man with transglottic squamous cell carcinoma with cartilage erosion. (A) Image through the supraglottis demonstrates a mass (M) involving the right paraglottic space and aryepiglottic fold. Normal fatty left paraglottic space (*) and aryepiglottic fold (white arrow) are indicated. (B) At the glottic level, the right true vocal cord is grossly enlarged by the mass (M) and the soft tissue of the anterior commissure (*) is grossly thickened. The left true vocal cord is irregular, also a consequence of tumor infiltration. (C) At the level of the undersurface of the vocal cords, the lesion has eroded the ventral aspect of the thyroid cartilage (T; arrowheads indicate mass) and has extended anteriorly to invade the strap muscles. (D) At the subglottic level, asymmetric soft tissue is seen anteriorly (arrowhead), consistent with subglottic tumor extension. Note that at the subglottic level, the air column should appear to be immediately adjacent to the cricoid cartilage with no significant intervening soft tissue.
