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.
