Summary
A rare orbital osteoma in a cat was successfully removed via subtotal orbitectomy. This case highlights a successful surgical outcome for a challenging periorbital tumor in a feline patient.
Area of Science:
- Veterinary Medicine
- Oncology
- Ophthalmology
Background:
- Periorbital tumors are uncommon in companion animals, with most being malignant.
- Osteomas, benign bone tumors, typically affect the mandible in felines, with orbital involvement being rare.
Observation:
- A 14-year-old Siamese cat presented with anorexia and a left periorbital mass.
- Radiographic imaging revealed a well-defined lesion consistent with new bone formation without bone destruction.
Findings:
- Histopathology confirmed the diagnosis of orbital osteoma.
- A subtotal orbitectomy was performed, removing the tumor with a 1 cm margin.
- The cat experienced no surgical complications and recovered appetite and activity within 15 days.
Implications:
- This case demonstrates the successful surgical management of an orbital osteoma in a cat, a rare presentation.
- Subtotal orbitectomy can be a viable treatment option for advanced orbital tumors, despite surgical complexities.
- Early diagnosis and surgical intervention are crucial for favorable outcomes in feline periorbital tumors.
