Moyamoya syndrome is a cerebrovascular disorder characterized by bilateral stenosis and occlusion of the internal carotid arteries and their branches. A 45-year-old woman with a history of systemic lupus erythematosus was admitted for recurrent ischemic strokes. Magnetic resonance (MR) angiography revealed moyamoya-like vasculopathy. Black-blood gadolinium-based contrast-enhanced MR images showed strong, concentric enhancement along the occluded arteries, which suggested vasculitis as the etiology of moyamoya-like vasculopathy. Intensive immunosuppressive therapy combined with anticoagulation therapy and rehabilitation led to a favorable outcome in this case. Black-blood MR imaging can be a non-invasive and prompt imaging modality when central nervous system vasculitis is suspected.
