Takayasu’s Arteritis (TA) is a disease of unknown etiology with incidence between 1.2 to 2.3 cases per million per year. It is a chronic granulomatous arteritis affecting large elastic arteries, predominantly the aorta, its main branches, pulmonary and coronary arteries characterized histologically by an inflammatory cell infiltrate that affects all the layers of the arterial wall. The etiology of TA is not clear but a causal relationship between TA and tuberculosis (TB) have been suggested. The first case of Takayasu’s arteritis was described in 1908 by Japanese ophthalmologist Mikito Takayasu. Despite the association with tuberculosis and the similarity between granulomatous lesions in both the diseases, the exact role of Mycobacterium tuberculosis in the pathogenesis of TA is still unknown
