Spinal Stenosis Syndrome (SSS) causes varying radiculopathies and myelopathies by compressing the spinal cord, rootlets and nerves within the bony canal. An enlarged and ossified posterior longitudinal ligament, a rare cause of the syndrome, can occupy up to 80% of the cervical spinal canal resulting in severe, sometimes permanent myelopathy. The clinical and the radiographic findings are discussed.
