title: Magnetic resonance imaging for the study of cervical myelopathy in rheumatoid arthritis.
abstract: Cervical myelopathy is found fairly often with rheumatoid arthritis. It is one of the worst complications of the disease and can lead to tetraplegia or even to sudden death. However, when we consider the high incidence of involvement of the cervical spine in rheumatoid arthritis, the number of cases of cervical myelopathy, even of slight degree, is not very high. We have used magnetic resonance to identify the condition of the cervical structures, especially the nerve structures, in 15 patients with rheumatoid arthritis, with involvement of the cervical articulations but without neurological symptoms. We found anterior compression of the spinal cord caused by the odontoid process of the epistropheus in 13 cases. One case had lateral deviation of the spinal cord and another had compression of a vertebral artery. In another the lumen of the nasopharynx was decreased and one had posterior compression of the spinal cord by the posterior arch of the atlas. Magnetic resonance also makes it possible to detect a rheumatoid pannus on the affected articulations. We conclude that magnetic resonance is at present a useful instrument for evaluation of the presence of cervical myelopathy in rheumatoid arthritis patients, to prevent more serious complications.
