“Asymptomatic” Moyamoya Angiopathy: Is it Truly Asymptomatic?

Moyamoya angiopathy (MMA) is a chronic progressive occlusive intracranial vasculopathy characterized by angiographic findings of stenosis or occlusion at the terminal portion of the internal carotid artery (ICA) or proximal anterior cerebral artery (ACA) and/or middle cerebral artery (MCA) together with the abnormal vascular network (classically appears to be like “puff of smoke”) at the base of the brain.1,2 “Asymptomatic” MMA has been defined by previous absence of clinical and radiological evidence of ischemic or hemorrhagic episode in an angiographically proven MMA patient who are neurologically free, excluding those who have experienced any episo de suggestive of transient ischemic attack(TIA), cerebral infarction, intracranial bleeding, seizure or involuntary movement caused by MMA.
