Abstract
The differential diagnosis of chorea can be challenging in patients without a family history of Huntington’s disease or acute-onset hemichorea with stroke. A 50-year-old woman presented with generalized choreic movements and gait disturbance that first appeared 1?month previously. An extensive diagnostic workup including genetic testing, neuroimaging, and various laboratory investigations revealed that this patient had developed chorea as a result of mercury poisoning. She was treated successfully with chelation therapy. Key Words: Chorea, Mercury poisoning
