Thoracic ossification of ligamentum flavum manifesting holocord syringomyelia: case report

Abstract

It has been reported that syringomyelia is rarely associated with degenerative spinal disorders, but the case of holocord syringomyelia is never reported. We here present a case of a 59-year-old woman with right shoulder pain, dysesthesia of the right hand, and gait disturbance. Radiographically, examinations of the spine demonstrated holocord syringomyelia with ossification of ligamentum flavum at T2/3 level. Holocord syringomyelia was reduced remarkably after posterior decompression at the T2/3 level, and her symptoms also improved. We speculated that holocord syringomyelia might have developed due to craniospinal pressure dissociation caused by focal compression of dural sac from extradural degenerative change.
