Fig. 5From: Progressive stenosis and radiological findings of vasculitis over the entire internal carotid artery in moyamoya vasculopathy associated with graves’ disease: a case report and review of the literatureRadiological findings of vasculitis over the entire internal carotid artery. Six months after recurrence, 3D-T1WI (a) and CE 3D-T1WI (b) of the ICAs were performed (Upper 2 figures: axial images of the distal portion; Lower 2 figures: coronal images of the proximal portion in Figure a, b). a 3D-T1WI showed smooth, concentric wall thickening over the entire left ICA (arrow). b CE 3D-T1WI showed diffuse contrast enhancement on vessel walls (dashed arrow in Figure b) over the entire left ICA, suggesting vasculitis radiologically [23, 24]Back to article page
