Takayasu arteritis is a chronic vasculitis of unknown aetiology, which primordially affects the aorta and its primary branches. Current observations have revealed a high prevalence of other inflammatory diseases in patients with Takayasu arteritis and thus raised the possibility that Takayasu arteritis may be associated with abnormality of the immune system activated by other inflammatory disorders such as inflammatory bowel disease (Crohn?s disease, ulcerative colitis).
The association of Takayasu arteritis and ulcerative colitis has occasionally been reported, however the simultaneous occurrence of Takayasu arteritis and Crohn?s disease is rare.´We report three additional cases of adult female patients with Crohn?s disease and subsequent clinical manifestation of Takayasu arteritis.
