Increased MRI signal intensity in association with myelopathy and cervical instability: Case report and review of the literature

BACKGROUND Increased T2-weighted signal intensity in patients with cervical myelopathy has been extensively reviewed in the literature. A variety of etiologies with similar MRI appearances have been described; attempt at correlation of MRI findings with clinical presentation and outcomes after treatment has led to a limited consensus. METHODS We present a case of cervical myelopathy with associated hyperintense T2-weigrhted signal characteristics, secondary to cervical spondylosis and instability. RESULTS Rapid resolution of radiographic abnormalities after surgical decompression and fusion was noted. Clinical improvement did not parallel radiographic resolution. CONCLUSION These findings are important in considering the pathophysiology of MRI changes in cervical myelopathy. (C) 2000 by Elsevier Science Inc.
