Chorea--a presenting feature of giant cell arteritis.

Chorea occurs as a hereditary or non-hereditary disorder. Nonhereditary chorea most commonly occurs in rheumatic fever (Sydenham’s Chorea) but may also be encountered in other metabolic and systemic disorders. Green House and Albuquerque listed more than forty different causes of chorea. The etiology of non-rheumatic chorea may cause diagnostic difficulties, due to its rarity. We report a 75 years old patient with giant cell arteritis presenting as chorea. Introduction Chorea occurs as a hereditary or non-hereditary disorder.
