Canine systemic mycosis associated with Chaetomium globosum in a dog.

BACKGROUND

Disseminated mycoses other than aspergillosis are infrequently reported in dogs.

CASE REPORT: A 4-year-old female Labrador retriever was evaluated because of hyperthermia, cough and intermittent lameness. Computed tomography showed a soft tissue mass in the cranioventral mediastinum, severe left and central tracheobronchial lymphadenopathy, and moderate bilateral pleural effusion. Magnetic resonance imaging identified an irregular intra-axial well-defined contrast enhancing mass extending from the right frontal lobe to the right thalamus. Fungal culture yielded growth of Chaetomium globosum.

CONCLUSION

In this case, the authors report a systemic mycosis in a Labrador retriever caused by C. globosum. To the best of authors' knowledge, this is the first report of systemic disease by this species in veterinary medicine.
