We report the case of a 65-year-old Nigerian woman with thyrotoxicosis manifesting as choreoathetosis, which misdiagnosed as a seizure disorder. The movement abnormality was characterized by bilateral jerky, purposeless, intermittent, irregular, and sometimes writhing movements, predominantly in the distal joints. Thyroid function test showed elevated total serum triiodothyronine (T3) and thyroxine (T4), and reduced serum thyroid stimulating hormone (TSH). There was complete resolution of choreoathetoid movement after 1 week of propanolol use. The relationship between choreoathetosis and thyrotoxicosis is discussed.
