title: Isolated Medial Rectus Palsy: Rare Presentation of Mesencephalon Infarction.
abstract: Isolated medial rectus palsy due to mesencephalon lesion is extremely rare. We here describe a patient of midbrain infarction involving the medial rectus subnuclei presenting as isolated medial rectus palsy. Axial diffusion-weighted and coronal T2-weighted magnetic resonance imaging showed acute ischemic lesion in mesencephalon.
