Case History
An 8-year-old Thoroughbred gelding presented to the Charles Sturt University Veterinary Clinical Centre (CSUVCC) for recurrent unilateral epistaxis. The horse had a previous history of a traumatic head injury during a trailer ride approximately 3-months prior to presentation to CSUVCC, which resulted in a small circular fracture of the right frontal bone. Upper airway endoscopy and skull radiographs were conducted after the traumatic episode at a referring equine hospital which revealed a small progressive ethmoid hematoma (PEH). The PEH was then treated with sequential formalin injections via endoscopy. The hematoma was thought to have been notably reduced in size on recheck radiographs, however, the owner reported that the gelding had suffered continuous episodes of bilateral epistaxis that had been progressively worse in volume and duration over the past 6 weeks.
