Abstract:
An adult horse was diagnosed with a frontal and caudal maxillary sinus lipoma, which was surgically removed. This is the first known report of a sinus lipoma in a horse. Lipomas should be considered in the differential diagnoses of equine sinus masses; complete surgical excision appears to be curative.
