[An unusual cause of aorto-bronchial fistula: tuberculosis aortitis]

The aortic rupture in the pulmonary parenchyma or the bronchi rarely results in an haemoptysis. It means in most of the cases the rupture of an aortica aneurysm. We relate the observation of a aorto-bronchial fistula from a tuberculosa origin in an old woman case. Although the tuberculosa aortitis is becoming very exceptional, it still remains the cause of aorta rupture, with the formation of a false aneurysm which is rapidly fatal and so, it is important to search for it before any capricious haemoptysis.
