Myelopathy patients studied with magnetic resonance for multiple sclerosis plaques.
Seven patients with isolated spinal cord symptoms, and with evoked potential (EP) recordings and/or cerebrospinal fluid (CSF) findings supporting a demyelinating cause for their myelopathy, were examined with cervical and cranial magnetic resonance imaging (MRI). Lesions in the cervical spinal cord were detected in 6 of the patients, including 2 who also had disseminated lesions in the brain compatible with multiple sclerosis (MS). In one patient MRI of the cervical spinal cord was normal, while plaques were seen in the periventricular region of the brain and in the brain stem. Thus, in the 3 patients with cerebral plaques, MRI supported the diagnosis of MS by showing dissemination in space. In the remaining 4 patients MRI provided support for the diagnosis of MS by demonstrating the cervical spinal cord plaques while excluding other potential causes of myelopathy, such as spinal cord compression and intramedullary tumor.
