CT features of confirmed nasopharyngeal stenosis in 12 cats

The most frequently observed CT features in cats with NPS are marked, focal, abrupt narrowing of the nasopharyngeal lumen by a mildly contrast-enhancing soft tissue band in the caudal third of the nasopharynx and focal deviation of the soft palate dorsally at the NPS site. Identifying any of these CT features in the presence of compatible clinical signs should prompt further evaluation with retroflex nasopharyngoscopy to confirm the diagnosis of NPS and to direct appropriate treatment.
