A Case of Diffuse Idiopathic Skeletal Hyperostosis ( DISH ) Associated with Ossification of the Posterior Longuitudinal Ligament ( OPLL / 대한류마티스학회지

ABSTRACT

We experienced a case of diffuse idiopathic skeletal hyperostosis(DISH) associated with ossification of the posterior longitudinal ligament. A 58-year old man presented with clumsiness and hypesthesia of both hands. He showed weakness of sensory defit and weakness of motor function of hands. The lateral radiograph of cervical spine showed anterior hyperostosis and ossification of the posterior longitudinal ligament. A magnetic resonance image of cervical spine revealed a low-density defect posterior to cervical spine with evidence of spinal stenosis. Ossification of the posterior longitudinal ligament is a rare manifestation associated with DISH, and we report this case with a review of the literature.
