Jaw Dystonia and Reversible Basal Ganglia Changes as an Initial Presentation of Systemic Lupus Erythematosus

Dystonia as a manifestation of neuropsychiatric lupus erythematosus (NPSLE) is uncommon. We report a 25-year-old woman who experienced progressive confusion, reduced speech, and difficulty opening her mouth approximately 2 weeks after development of a facial rash. Brain imaging showed bilateral, symmetric signal abnormalities within the basal ganglia and subcortical white matter. Despite treatment with high-dose steroids, she continued to have difficulty speaking with evidence of jaw dystonia on examination. Jaw dystonia rapidly improved with the initiation of levodopa. Repeat evaluation 3 months later exhibited the absence of jaw dystonia and near resolution of the imaging abnormalities. Our patient demonstrated a unique presentation with jaw dystonia refractory to traditional treatment for NPSLE. Such a presentation likely represents a severe variant of NPSLE requiring both immunosuppressive and symptomatic therapies.

Movement disorders in systemic lupus erythematosus and the antiphospholipid syndrome

Movement disorders (MDs), particularly chorea, may be the presenting neurological complication of systemic lupus erythematosus (SLE) and the antiphospholipid syndrome (APS), but the association is not often initially recognized. Current evidence suggests an autoimmune mechanism related to antiphospholipid antibodies in these two conditions, although the antigenic target within the central nervous system has not yet been identified. Based on a comprehensive review of the literature, this article summarizes the current knowledge on MDs in SLE and APS. A high index of suspicion is required to make an early diagnosis and initiate appropriate treatment to provide symptomatic relief and to prevent other systemic complications related to the autoimmune process.
