Abstract
Chorea can be associated with autoimmune diseases such as antiphospholipid syndrome and has been associated with the isolated presence of antiphospholipid antibodies (aPL). Chorea is a rare neurological manifestation of antiphospholipid syndrome. The pathophysiological mechanisms underlying aPL-related chorea are still debated. One postulated mechanism is aPL or other autoantibody binding to brain-blood vessel endothelium, resulting in endothelial dysfunction secondary to a proinflammatory cascade, with sequalae of inflammation and local microthrombosis. Another postulated mechanism considers immune-mediated attack (aPL or antibasal ganglia antibodies) against specific basal ganglia epitopes. Here, we report a patient with isolated aPL-related chorea that followed a relapsing-remitting course. We highlight the role of brain metabolic imaging with fluorodeoxy glucose positron-emission tomography in the diagnostic workup of chorea and the challenges in the practical management of aPL-related chorea with symptomatic treatments.
