Occipital infarctions associated with hemiparesis.
71 patients with a CT-verified infarction in the irrigation area of the posterior cerebral arteries were studied retrospectively. In 17 subjects a hemiparesis was associated with the occipital infarction. The hemiparesis was not associated with brainstem symptoms and in none of these cases a concomitant infarction in the territory of the middle or anterior cerebral arteries was found. No adequate cause was found for the hemiparesis. A simultaneous lesion of one of the small penetrating branches of the posterior cerebral artery was thought to be a possible explanation.
