Title : An unusual case of Takayasu arteritis aneurysm
Takayasu Arteritis is a large vessel vasculitis more commonly affecting the aorta and its direct branches (Silver 2012). Cerebral aneurysms are uncommon; but associated with Takayasu's and are routinely found in areas of increased haemodynamic stress with a significant predilection for posterior circulation compared to the general population. This increased predilection is felt to be due to the increased pressure from an obstructed carotid system (Camara et al. 2016). We present the case and imaging of a patient with known Takayasu's arteritis and new right midbrain infarct secondary to compression from a known basilar artery aneurysm.
