Plain-English summary
An 11-year-old dressage mare was having trouble walking, and although a hoof abscess was suspected, it couldn't be seen. X-rays and a CT scan revealed a large cyst near the tip of her pedal bone and a smaller one on the side. Further examination showed that these were two cysts located in the third bone of her hoof. The tests confirmed that these cysts were epidermoid cysts, which are a type of growth that can occur in the bone.
Abstract
An 11-yr-old Dressage mare had abnormal gait, and an abscess of the left hoof was suspected but not observed. Radiographic and computerized tomographic evaluations showed a large cystic lesion near the apex of the pedal bone, and a smaller, similar lesion at the lateral wing. Sagittal sections through the affected member revealed two intraosseous cysts at the third phalanx. Histologic and histochemical results characterized the lesions as intraosseous epidermoid cysts of the third phalanx.
