[Magnetic resonance study of lesions of the cervical spinal cord in multiple sclerosis].
Lesions consistent with demyelinating plaques were retrospectively identified in the cervical spinal cord of 15/49 patients (31%) with multiple sclerosis examined with cranial and cervical MR imaging. The lesions appeared as hyperintense areas on proton-density and T2-weighted images. Clinical signs and symptoms suggestive of spinal cord location of the demyelinating plaques were observed in 14 of the 15 patients presenting with spinal cord lesions at MR, and also in 11 of the 34 patients with negative MR findings. In 2 patients the cervical lesion was not associated with brain lesions at MR, while in 1 patient it was associated with medullary dilatation. Serial MRs revealed disappearance of the cervical hyperintense area in both patients, and reduction in medullary volume in the latter. Therefore, MR imaging of the cervical spinal cord is suggested as an useful examination in patients with suspected multiple sclerosis, particularly in those presenting with clinical signs and symptoms suggestive of spinal cord involvement.
