Abstract
A 56-yr-old hypertensive male presented with left-sided weakness of 2-h duration. He made complete recovery from right hemiparesis due to left parietal infarct. Examination showed dysarthria and left hemiparesis (NIHSS 8/42). MR-brain showed both left parietal acute infarct and gliosis from old infarct (Figure-1). He was successfully thrombolysed with intravenous alteplase. Present stroke was diagnosed as ipsilateral hemiparesis, confirmed by DTI (Figure-2). Ipsilateral hemiparesis, mostly seen with posterior fossa malformations and remote infarctions, results from injury to uncrossed corticospinal tract (CST) in patients of remote brain injury or with no decussation of CST or injury to ipsilateral extrapyramidal motor pathway.
