Plain-English summary
A 2-year-old Thoroughbred filly had a problem with a runny nose that lasted for a month. After some imaging tests, vets found a mass in her right maxillary sinus that connected to other areas in her head. During surgery, they removed this mass, which looked like a bony structure with smooth tissue on the outside and contained fluid-filled cysts inside. After the surgery, the filly no longer had any nasal discharge, indicating that the treatment was successful.
Abstract
A 2-year old Thoroughbred filly was examined for a 1-month history of persistent nasal discharge. Contrast radiography revealed a circumscribed mass within the right maxillary sinus which extended to the frontal sinus and ethmoid labyrinth. A discrete attachment of the mass to the ethmoid labyrinth was identified at surgery. Surgical removal of the mass eliminated the nasal discharge. On gross examination, the external structure of the mass was similar to a turbinate with a thin bony wall covered by a smooth mucosal membrane. The internal structure of the lesion had a lining membrane with multiple 1-3 cm in diameter fluid filled cystic structures. The histological appearance of the multiloculated structure was similar to the ethmoid labyrinth. This, combined with the single site of attachment to the ethmoid labyrinth, suggested that the cyst was ethmoidal in origin.
