Summary A 13‐year‐old, crossbred grey mare was referred for examination of a left‐sided head tilt and neck stiffness which had been noted for several months. Radiographic examination of the head revealed severe periarticular bone formation surrounding the dorsal and ventral margins of the atlanto‐occipital joint and a large multilobular bony mass encroaching on the guttural pouch. Computed tomographic examination confirmed a multiloculated bony mass invading the vertebral canal and causing marked spinal cord compression and displacement. Histologically, this was identified to be an osteochondroma and the horse was conservatively managed.
