Plain-English summary
A group of 46 dogs with nasal aspergillosis, a fungal infection, underwent tests to check for fungal plaques in their noses and sinuses. In most cases, 38 dogs had visible plaques in their nasal cavity, while 8 had plaques only in their frontal sinuses. The study found that dogs with signs of nasal issues often had sinus involvement as well, suggesting that additional procedures like sinuscopy could help diagnose the condition more effectively. Treatment typically involves antifungal medications, and many dogs improve with appropriate care.

Abstract
OBJECTIVE: To determine results of diagnostic testing, including detection of nasal or frontal sinus fungal plaques, in dogs with nasal aspergillosis. DESIGN: Retrospective case series. ANIMALS: 46 dogs with nasal aspergillosis. PROCEDURES: Medical records were reviewed for information on computed tomographic findings; rhinoscopic findings, including whether fungal plaques were seen in the nasal cavity; results of frontal sinus trephination and sinuscopy, including whether fungal plaques were seen in the frontal sinus; and results of histologic examination of biopsy specimens. RESULTS: In 38 (83%) dogs, fungal plaques were seen in the nasal cavity during rhinoscopy, whereas in the remaining 8 (17%), fungal plaques were not seen in the nasal cavity but were seen in the frontal sinus. Duration of clinical signs, proportions of dogs in which the referring veterinarian had performed a nasal examination prior to referral, proportions of dogs with computed tomographic evidence of nasal cavity cavitation or sinus involvement, and proportions of dogs with rhinoscopic evidence of destructive rhinitis were not significantly different between dogs with nasal fungal plaques and dogs with fungal plaques only in the frontal sinus. CONCLUSIONS AND CLINICAL RELEVANCE: Results confirm that frontal sinus involvement is common in dogs with nasal aspergillosis and suggest that frontal sinus trephination and sinuscopy may aid in the diagnosis of aspergillosis in dogs, particularly dogs with rhinoscopic evidence of destructive rhinitis and computed tomographic evidence of sinus involvement that lack detectable fungal plaques in the nasal cavity.
