8歳の男児が、1日の間に突然発症した両眼性垂直複視を訴えた。眼科検査では、回転性眼振を伴う上下動の制限が認められた。全身検査では，鉄欠乏性貧血と上中脳左傍吻合部と背側部に赤核レベルでの局所急性梗塞が磁気共鳴画像で認められた．鉄剤の経口投与を開始し，2週間後には臨床的にも症状も改善した．

An 8-year-old boy presented with complaints of sudden-onset binocular vertical diplopia of one day duration. Ophthalmic examination showed restricted up- and downgaze movement with rotatory nystagmus. Systemic investigations revealed iron-deficiency anemia and localized acute infarct in the left paramedian rostral and dorsal part of the upper midbrain at the level of the red nucleus on magnetic resonance imaging. The patient was started on oral iron supplement, which resulted in symptomatic as well as clinical improvement after 2 weeks.
