title: Cavernous angioma with olivary hypertrophy and contralateral cerebellar diaschisis.
abstract: We describe a 66-year-old man with a 20-year history of ataxic gait who suddenly developed diplopia on rightward gaze. Neurologic examination revealed right hemi-ataxia and hemi-hypesthesia, and left internuclear ophthalmoplegia. MRI showed a cavernous angioma in the left tectum, mild right cerebellar atrophy, and left interior olivary hypertrophy. Single photon emission computed tomography (SPECT) imaging demonstrated contralateral cerebellar diaschisis. We discuss the findings and review the literature concerning contralateral cerebellar diaschisis.
