Clinic Explanation:
Ethmoid hematoma is a progressive and locally
destructive disease of horses. It is indicated by a mass in the paranasal sinuses that resembles a tumor but is not neoplastic by any means. Most common clinical
signs of the disease include a mild, intermittent nose bleed from one nostril. If
the mass is large it may cause abnormal respiratory noise and can occasionally
cause malodorous breath.
Treatment consists of
removing the mass and the tissue of origin.
