Isolated Gait Ataxia Due to Cerebellar Vermis Infarct

Arch Neurol. 2004;61(9):1461. doi:10.1001/archneur.61.9.1461

Two patients developed an acute inability to stand or walk and a tendency to fall backward without dysarthria, limb ataxia, or other neurological or cerebellar signs. An acute infarction of the rostral vermis (in the territory of the medial branches of the superior cerebellar artery) was confirmed with diffusion-weighted magnetic resonance imaging (Figure). Both patients improved and could walk in 4 to 7 days.
