History: Two DSH cats from the same household each became sick with fever, lethargy, and respiratory distress. Treatment was tried but unsuccessful.
Lung: Pyogranulomatous bronchopneumonia, severe multifocal, with vasculitis, hemorrhage and intralesional fungal hyphae consistent with Aspergillus sp.
Trachea: Pyogranulomatous tracheitis, moderate, multifocal
We did a fungal culture but were not able to grow anything. The morphology of the hypahe: septate, dichotomous branching is consistent with Aspergillus sp.
