An enhancing soft tissue thickening is observed in the right pyriform sinus, involving its anterior wall (arrow, corresponds to posterior side of aryepiglottic fold), lateral wall (small arrowhead), and posterior wall (large arrowhead).
 
About 1 cm more caudally, the enhancing soft tissue mass extends between the right arytenoid cartilage (a) and thyroid infiltrate into the paraglottic space (white arrowhead); the mass nearly reaches an unossified island in the thyroid cartilage (black arrowhead). Extension in the anterior submucosal layer of the inferior hypopharynx is visible (asterisk). The posterior submucosal layer does not appear to be infiltrated (arrow). On the left side, the different tissue layers of the inferior hypopharynx are labeled: m = opposing anterior and posterior mucosal layers; 1 = anterior submucosal fat; 2 = posterior submucosal fat; 3 = inferior pharyngeal constrictor muscle.
 
Three mm caudal to fig. 2. The soft tissue mass infiltrates the laryngeal paraglottic space (arrow) and anterior submucosal hypopharyngeal layer; the posterior submucosal layer is intact (arrowheads). Arytenoid cartilage (a); cricoid cartilage (c).
 
Six mm caudal to fig. 3. Subtle infiltration of the anterior submucosal layer can still be seen. Cricoid cartilage (c); 1 = anterior submucosal fat; 2 = posterior submucosal fat; 3 = inferior pharyngeal constrictor muscle.
 
Three mm caudal to fig. 4. At this level, the posterior cricoarytenoid muscle (dots) can be recognized between the cricoid arcus (c) and the anterior submucosal layer (1). At the side of the lesion, the anterior submucosal layer still appears infiltrated. 2 = posterior submucosal fat; 3 = inferior pharyngeal constrictor muscle.
 
Nine mm caudal to fig. 5. The esophageal verge (arrowheads) has a more ovoid appearance compared with the appearance of the postcricoid region. At this level, no abnormality is visible anymore.
 
Nine mm caudal to fig. 6. At this level, the esophagus (arrowheads) has a rounded appearance.
