A six-year-old, 3.7 kg, female domestic cat was brought to us with paralysis of the hindlimbs. Radiography, myelography, and computed tomography revealed a solitary exostosis at the seventh cervical vertebra (C7), and compression of C6, C7, and the first thoracic vertebra (T1). Laminectomy and facetectomy were performed in order to decompress the spinal cord and remove the exostosis, and we managed to remove the lesion. From the cat's medical history, the exostosis was suspected to have developed long before the first visit to us, and discolored spinal cord was observed during the surgery, so that a poor prognosis of neurological symptoms was predicted. In spite of post-operative intensive care, the cat died on the 12th post-operative day. Still, CT was useful in detecting the exostosis in this case. Generally, if a solitary exostosis is detected before neurological symptoms develop, surgical removal of it will enable the animal to live longer and enjoy better quality of life.
