case_images: Endoscopy revealed an elevated lesion anterior to the right wall of the oropharynx (shown in Fig. 1). Cervicothoracic contrast-enhanced computed tomography revealed a tumor, with a maximum diameter of 26 mm, with a contrast effect in the anterior to the right lateral wall of the oropharynx (Fig. 1).
case_images: Endoscopic findings and contrast-enhanced computed tomography. Endoscopic findings: tumor on the anterior wall of the mid-pharynx. Contrast-enhanced computed tomography: tumor in the anterior wall of the mid-pharynx, with no infiltration of the parapharyngeal space (red arrow). The right upper internal deep cervical lymph node was enlarged (yellow triangle).
