Spectrum of central nervous system involvement in rheumatic diseases: pictorial essay

The rheumatic diseases, which include systemic lupus erythematosus, rheumatoid arthritis, Behçet's disease, scleroderma, and ankylosing spondylitis, are characterized by involvement of connective tissue, with multiple manifestations. In those diseases, there can be involvement of the peripheral or central nervous system, and that involvement can be primary, presenting as a major feature of the clinical presentation, or secondary, as an effect of the drugs used in order to control a given disease or its complications. Knowledge of the wide variety of imaging findings is crucial to the diagnosis of a rheumatic disease, especially in the early stages, enabling effective treatment and minimizing disability. This pictorial essay, presenting cases from the records of two tertiary teaching hospitals, encompasses cases of patients diagnosed with rheumatic disease and illustrates the neuroradiological findings on magnetic resonance imaging and computed tomography, in order to emphasize the importance of these methods for properly diagnosing rheumatic diseases.
