case_images: (a) Preoperative laryngoscopy showing poor mobility of the left vocal cord and a smooth-surfaced neoplasm under the vocal folds. (b) Preoperative imaging revealed a soft tissue nodular shadow in the anterior laryngeal wall under the vocal folds, measuring approximately 14 x 13 mm. (c) The soft tissue strengthened significantly and the laryngeal cavity narrowed.

case_images: A pink mass with a smooth surface was found under the glottis (Figure 1a). Enhanced CT revealed a soft tissue nodular shadow in the anterior wall of the subglottic larynx measuring approximately 14 x 13 mm in size (Figure 1b), this shadow was significantly intensified after enhanced scanning (Figure 1c), and the laryngeal lumen was narrowed; thus, we considered the possibility of malignancy.
