Chorea secondary to human immunodeficiency virus infection

A 55-year-old woman presented with facial and cervical chorea for 3 months (video). She had a previous history of traumatic right facial nerve palsy but no comorbidities or current medication use. Brain magnetic resonance imaging (MRI) was performed ([Figure 1]). Cerebrospinal fluid analysis was unremarkable. Serum tests were positive for human immunodeficiency virus (HIV) type 1 with 1.877.056 viral copies and T-CD4 lymphocyte count of 35/mm3. Darunavir, ritonavir, dolutegravir, and lamivudine were initiated. After 4 months, chorea showed resolution ([Video 1]). Chorea is a rare manifestation of HIV infection.[1] [2] Differential diagnoses like neurosyphilis, Huntington disease, and Wilson disease should be ruled out.[2]
