Rare Presentation of Midbrain Infarction: Isolated Medial Rectus Palsy

Abstract

A 69-year-old woman presented with sudden onset of diplopia. In neurologic examination left medial rectus palsy without abduction nystagmus was detected. Brain magnetic resonance imaging revealed acute ischemic lesion in mesencephalon on diffusion-weighted images. Sponteneous resolution was observed after 1 month. Medial rectus palsy is a rare presention of acute ischemic stroke and early neuroimaging is important to establish such lesions. (C) 2015 S. Karger AG, Basel
