A repeat rhinoscopy on my 11 year old cat revealed new tissue growth in the nasopharyngeal space with a very small polyp that has not changed in size since last year. The new tissue growth and polyp was biopsied again (last year it was negative) for cancer which is what the vet suspects. Her labs are all normal. I will have a definitive diagnosis in 3-5 days. If it comes back negative again, it would be highly indicative of Nasopharyngeal Stenosis according to the vet. Has anyone out there had any experiences with this possible diagnosis? In the meantime my kitty continues to have very noisy and difficulty breathing with trouble swallowing her food. The nasopharyngeal flush did nothing to improve her symptoms this. I am doing my best to keep her calm and adding water to her pate food to assist with eating as she still has a very good appetite. Any help would be greatly appreciated.
