Inflammatory Polyps
RespiratoryFelineNew
Key Points
  • Inflammatory polyps are benign, non-neoplastic masses that most commonly arise in the nasopharynx, Eustachian tube or middle ear
  • They are most commonly seen in young cats (<3 years old)
  • Although the definite cause is unknown, they are thought to be related to chronic inflammation (e.g. feline herpesvirus-1, chronic otitis interna)
  • The clinical signs vary with the location of the polyp but sneezing, nasal discharge and stertor are common
  • A presumptive diagnosis can be based on clinical signs and imaging but definitive diagnosis requires histopathology
  • The primary treatment is removal
  • Recurrence is common if the inflammatory tissue is not completely removed
Differential Diagnoses
  1. Nasopharyngeal / aural neoplasia
  2. Chronic otitis media or interna
  3. Nasopharyngeal stenosis
  4. Nasopharyngeal / aural foreign body
