Dorsolateral pontine hemorrhage producing pure sensory stroke

Pure sensory stroke predominantly results from lacunar infarction in the posteroventral nucleus of the thalamus. We report the history of a young nonhypertensive male presenting with pure sensory stroke due to hemorrhage of a small arteriovenous malformation in the dorsolateral part of the pons. In contrast to the extent of the lesion, only minor degree of objective sensory loss was observed. Furthermore, our observation is unique in that it is the first presentation of this syndrome with that particular location.
