Claude Syndrome: A Rare but Easily Recognizable Midbrain Lacunar Syndrome.

Claude syndrome (CS) is a rare and classic neurological condition resulting from an isolated midbrain infarction (IMI). Its clinical presentation and anatomical localization remain subjects of ongoing debate in the literature. We present the case of a patient evaluated at our stroke center, with neuroimaging and video documentation of her resolving deficits. In addition, we provide a review of the syndrome's history, epidemiology, clinical features, and potential etiologies.
