British Shorthair cat with sinonasal aspergillosis at presentation: (a) haemopurulent nasal discharge; (b) oral examination, note the absence of a mass or ulceration in the pterygopalatine fossa commonly seen in sino-orbital aspergillosis; (c) anterograde rhinoscopy left nasal meatus, polypoid and hyperplastic appearance of nasal mucosa in the left nasal meatus; (d) anterograde rhinoscopy left nasal meatus, fungal plaques adherent to nasal mucosa; (e) retroflexed pharyngoscopy, fungal plaques visualised in the choanae; (f) fungal plaques removed with active debridement

Fungal plaques were observed adherent to nasal mucosa and surrounded by polypoid tissue (Figure 1). Both nasal cavities were aggressively debrided of fungal plaques using 3 mm cupped biopsy forceps (Karl Storz 69133) at premeasured depths following confirmation of plaque locations on rhinoscopic evaluation (Figure 1).
Anterograde rhinoscopy. Left nasal meatus 6 months after diagnosis: fungal plaques and polypoid appearance of nasal mucosa, confirming relapse of infection

Fungal plaques were identified in the left nasal cavity at the level of the ethmoid turbinates in the middle nasal meatus (Figure 2).
Twelve months after diagnosis: (a) mucopurulent nasal discharge; (b) anterograde rhinoscopy showing atrophic rhinitis and sinus exposure

Areas of polypoid tissue involving the dorsal and middle meati were also seen (Figure 3).The right nasal cavity was similarly but less severely affected.
