Neurological signs due to foraminal stenosis associated with disseminated idiopathic spinal hyperostosis were found in two dogs. Spondylosis deformans was associated with foraminal stenosis and/or disc protrusion in 15 cases</bold>.</p> <p id="jsap12218-para-0004"> <bold>The Pfirrmann score on magnetic resonance imaging was significantly higher in spondylosis deformans compared with disseminated idiopathic spinal hyperostosis and signal intensity of new bone due to disseminated idiopathic spinal hyperostosis was significantly higher compared to spondylosis deformans</bold>.</p> </sec> <sec id="jsap12218-sec-0004" sec-type="section"> <title>CLINICAL SIGNIFICANCE</title> <p id="jsap12218-para-0005"> <bold>Differences between disseminated idiopathic spinal hyperostosis and spondylosis deformans found on magnetic resonance imaging contribute to an increased differentiation between the two entities. Clinically relevant lesions in association with disseminated idiopathic spinal hyperostosis were rare compared to those seen with spondylosis deformans</bold>.</p> </sec> </abstract>
