Unusual manifestations of thalamic strokes.
Four patients of thalamic strokes with different symptoms are reported. The first had thalamic haemorrhage and developed delayed blepharospasm. The second patient had occlusion of posterior cerebral artery causing infarction of lateral thalamus and occipital lobes. The remaining two patients exhibited ipsilateral hemisensory loss and hemiataxia in absence of hemiparesis (thalamic ataxia). Both had circumscribed lesions in lateral thalamus. 'Thalamic ataxia' has a distinct localizing value. Thalamic strokes produce heterogenous clinical manifestations attributed to the involvement of different nuclei.
