CT revealed a laryngeal tumor that compromised vocal cords, glottis, cricoid and thyroid cartilage of 3 x 2.7 cm in diameter and 4 cm in length (Fig. 1).
Glottic stenosis due to lesion covered by normal appearance mucosa with subglottic extension. The tumor apparently originates from the cricoid cartilage, has a solid surface, bright, white and measures 3.5 x 2 x 2 cm. The tumor expands the cartilage and infiltrates the mucosa without ulcerating it and infiltrates both paraglottic spaces with the pre-epiglottic space free of tumor.
