Plain-English summary
A 7-year-old Thoroughbred mare was found to have bony growths along the seams of her skull, which were causing her tear ducts to be partially blocked. She had been experiencing chronic tearing and changes in her facial shape. Doctors used advanced imaging techniques to confirm the diagnosis and also found some minor fractures in her right nasal and facial bones. After treatment, the mare's appearance and the issues with tearing improved significantly within three months.
Abstract
A definitive diagnosis of extensive suture line exostoses affecting the nasofrontal, nasolacrimal, nasomaxillary, frontolacrimal, lacrimozygomatic and lacrimomaxillary suture lines in a 7-year-old Thoroughbred mare with chronic bilateral epiphora and facial deformation was achieved using standing computed tomography (CT) examinations. Positive contrast dacryocystorhinography using CT revealed partial bilateral obstruction of the nasolacrimal ducts. Minimally displaced depression fractures of the right nasal bone, the right maxillary bone and right frontal bone were also demonstrated. The cosmetic appearance of the periosteal reaction associated with the suture line exostosis and epiphora significantly improved within 3 months of diagnosis and treatment.
