title: Chorea-acanthocytosis: a case report.
abstract: Neuroacanthocytosis is a group of rare disorders. We report a 36-year-old right-handed female who presented with gradually progressive abnormal facial movements, generalized weakness, and lower-lip biting starting 4 years ago. On examination, she had lower-lip ulcer, orofacial dyskinesias, and peripheral neuropathy. Her peripheral blood smears showed acanthocytosis and magnetic resonance imaging revealed atrophied head of caudate nuclei and putaminal hyperintensities on T2-weighted and fluid attenuated inversion recovery images. Work-up for autoimmune and metabolic causes was negative. She was diagnosed with chorea-acanthocytosis, an entity under neuroacanthocytosis syndrome and the patient was offered symptomatic treatment.
