Association spondylarthrite ankylosante - maladie de Takayasu. Une nouvelle observation

Ankylosing spondylarthritis and Takayasu aorto-arteritis are two inflammatory diseases with a not yet elucidated pathogenic mechanism. Their association is quite exceptional with only a few cases (14) being published in the literature. We report a new case in a 26-year-old woman whose Takayasu disease led to stenosis of the subclavian artery and the thoracic aorta 9 years after diagnosis of ankylosing spondylarthritis with sacro-iliac involvement. This association is probably not fortuitous.
