Abstract: A 49-year-old wheelchair-bound man was rendered left hemiparetic, dysarthric, and diplopic after a brainstem hemorrhage.Several months later he developed a progressively disabling left arm tremor.Examination showed skew deviation, left hemipare-sis, left hemianesthesia, truncal ataxia, and a postural and action proximal left arm tremor (video).Brain MRI demonstrated a cavernous malformation in the right upper brainstem and enlarged ipsilateral inferior olivary nucleus secondary to a lesion in the central tegmental tract (figure).Cerebellar limb tremor is associated with contralateral hypertrophic inferior olive, analogous to secondary palatal tremor, 1 whose delayed onset by weeks or months after injury may be due to compensatory changes in the motor system. 2
