Fig 1. Axial T1-weighted postcontrast MR image in a 44-year-old man with a small contrast-enhancing polyp (arrow) arising from the posterior wall of the lower nasopharynx 11 years after chemoradiotherapy. Posttreatment scarring is present in the left lateral nasopharyngeal wall, partially effacing the parapharyngeal fat, and around both carotid sheaths.
