Abstract

This report describes a patient presenting with a spastic quadriplegia who was found to have both diffuse idiopathic skeletal hyperostosis (DISH) and ossification of the posterior longitudinal ligament (OPLL) in the cervical spine. There was a dramatic worsening of his symptoms during a myelogram examination of the neck. It is suggested that computed tomographic imaging of the neck is the preferred investigative procedure if OPLL is suspected as a cause of cervical myelopathy.
