Nasopharyngeal disorders in feline patients can be challenging to diagnose and treat effectively. This is a case of a 13-year-old male castrated domestic shorlhair cat who presented to the Internal Medicine service with a complaint of chronic upper respiratory disease manifesting primarily as sneezing, stertorous breathing, and nasal discharge. The patient had been treated with a variety of antibiotics, antiintlammatories, and antihistamines, with only temporary, partial resolution of clinical signs. A complete workup for diagnosis of chronic upper respiratmy disease was performed, including minimum database, fungal serology, advanced imaging, and retroflex rhinoscopy with antegrade biopsy. Differential diagnoses for this case included acute infectious causes such as bacterial, viral, fungal, or parasitic causes. Other differentials included foreign body, neoplasia, nasopharyngeal polyp, nasopharyngeal stenosis, and chronic inflammatmy rhinitis. Initial diagnostics such as serology, eulture, and infectious agent isolation did not yield a diagnosis. Computed tomography (CT) sean of the head and thorax and retroflex endoscopy of the nasopharynx diagnosed nasopharyngeal stenosis as the cause oft.he patient's clinical signs. Treatment options for nasopharyngeal stenosis include medical management, balloon dilation or placement of a stent, each of which have advantages and disadvantages. Establishing a successful treatment regimen for nasopharyngeal stenosis secondary to chronic upper respiratory disease case can therefore be challenging.
