Abstract:
A 66-year-old man presented with axial lateropulsion, exhibiting sudden falling as the sole clinical sign of cerebellar infarction in the territory of the medial branch of the superior cerebellar artery (mSCA). A brain MRI showed acute infarction selectively involving the centralis of the rostral vermis. This patient illustrates that cerebellar infarction in the territory of the mSCA can present as an isolated body lateropulsion. The possible mechanism of an isolated body lateropulsion is considered.
