Plain-English summary
A 1-year-old male Korat cat was brought to the vet because of a noticeable difference in pupil size (anisocoria) and other eye issues, along with severe spinal pain and jaw deformities. The vet suspected cavernous sinus syndrome, which can affect the nerves around the eyes, and found multiple abnormal bone growths through X-rays and a CT scan. Unfortunately, due to the severity of the cat's condition and extreme pain, the decision was made to euthanize him. The final diagnosis was a widespread skeletal and brain condition called osteochondromatosis, which caused the various symptoms.

Abstract
A 1-year-old sexually intact male Korat cat was referred for ophthalmological consultation due to anisocoria. Mydriasis with external ophthalmoplegia and absence of pupillary light responses in the right eye and nasofacial hypalgesia were seen. Cavernous sinus syndrome (CSS) was suspected. Bilateral deformities of the jaw and phalangeal bones, severe spinal pain and abnormal conformation of the lumbar spine were also present. Radiographic examination revealed several mineralised masses in the appendicular and axial skeleton, indicative of multiple cartilaginous exostoses. For further investigation of the CSS-related neurological deficits, the cat underwent computed tomography (CT) examination of the skull. CT images revealed a non-vascularised, calcified, amorphous mass originating from the right lateral skull base and superimposing on the sella turcica. Based on the severity of diffuse lesions and owing to the clinical signs of extreme pain, the cat was euthanased. A diffuse skeletal and intracranial osteochondromatosis was diagnosed histologically.
