Q

What diagnostics need to be ran in a cat with external ulcers around the face, exopthalmos, absent airflow, and unilateral mucopurulent nasal discharge?

A

All clinical signs of fungal rhinitis (crypto)

  • MDB, FELV, FIV
  • Thoracic rads (R/O metastatic neoplasia)
  • Cytology + culture of nasal d/c
  • CT (Fungal rhinitis won’t cause bone lysis)
  • Rhinoscopy with biopsy (after CT- more invasive, can skew results if done before)
15
Q
