Abstract

Moyamoya disease (MMD) is a rare cerebrovascular disease characterized by idiopathic occlusion of bilateral internal carotid arteries and the development of characteristic leptomeningeal collateral vessels along anterior or posterior circulation. We present an unusual case of MMD presenting with generalized dystonia as the predominant manifestation.

Keywords: Dystonia; magnetic resonance angiography; moyamoya.
