Calcified tumours of the paranasal sinuses in three horses.
Abstract: Three horses, a 10-year-old Thoroughbred mare, a 9-year-old Thoroughbred gelding and a 6-year-old Arab gelding, with calcified tumours of the paranasal sinuses, are described. All horses presented with purulent nasal discharges and facial distortion. Exophthalmos, blepharospasm and ocular discharge were also a feature in individual horses. A presumptive diagnosis of a calcified tumour was made on the basis of clinical signs and radiographic and endoscopic findings. The tumours ranged from 15 to 25 cm in diameter. A large frontonasal bone flap was used to expose the tumours, which were cleaved into several pieces with an osteotome and removed. Histological examination of the masses identified cementomas in two cases and an osteoma in the third. Long term follow up from 18 months to 5 years after surgery indicated that there was no recurrence. This case series demonstrates that, although calcified tumours of the paranasal sinuses are rare in horses, they should be considered in the differential diagnosis of purulent nasal discharge, facial swelling and ocular distortion, and are amenable to surgical treatment.

This research explores a case series involving three horses who developed calcified tumors in their paranasal sinuses. The study identifies the respective symptoms, diagnostic methods, surgical treatment, and long-term outcomes for these animals.
Background and Study Objective
- The research begins by explaining that calcified tumors in the paranasal sinuses of horses are rare.
- The paper highlights three cases of horses diagnosed with such tumors—two Thoroughbreds and one Arabian horse.
- The aim of the research is to highlight the symptoms of these tumors and the surgical procedures used for their removal.
- The study also confirms the long-term effectiveness of the surgical treatment.
Symptoms and Diagnosis
- All three horses presented with purulent (pus-forming) nasal discharge and facial distortion as primary symptoms.
- Individual horses also displayed symptoms like exophthalmos (bulging eyes), blepharospasm (involuntary blinking or spasm of the eyelids), and ocular discharge.
- The veterinarians used clinical signs, radiographic imaging, and endoscopy to diagnose these horses with calcified tumors. The tumors ranged between 15 and 25 cm in diameter.
Surgical Treatment and Follow-Up
- The surgical treatment was carried out by exposing the tumors through a large frontonasal bone flap.
- The surgeons then cleaved the tumors into several pieces using an osteotome and then removed them.
- A histological examination post-surgery identified two cases to be cementomas (benign tumors of the cementum in teeth) and one case to be an osteoma (a new piece of bone usually growing on another piece of bone).
- Long-term follow-up extending from 18 months to 5 years after surgery showed no recurrence.
Conclusion
- The study concludes by underlining the importance of including calcified tumors in differential diagnosis when attending to horses with purulent nasal discharge, facial swelling, and ocular distortion.
- It also highlights and affirms the effectiveness of surgical treatment in these cases.
