Abstract
- Neurological manifestations as extra-articular features of ankylosing spondylitis (AS) have not been reported often, and present as root lesions, cauda equina syndrome, and compression of the spinal cord. We report a 31-year-old man who complained of back pain and claudication of both lower extremities. The patient showed typical inflammatory back pain and significant sacroiliitis, consistent with AS. He also had mechanical back pain and unexplained neurological symptoms. A neurological evaluation, including spinal magnetic resonance imaging and a cerebrospinal fluid study, revealed that the patient had acute transverse myelitis (ATM). ATM can be associated with connective tissue diseases. The pathophysiology of ATM consists primarily of inflammatory disorders, similar to the neurological complications of AS. We suggest that ATM is a possible extra-articular manifestation of AS.
