Cerebral infarction and subdural hematoma. Advantage of nuclear magnetic resonance imaging in cerebral ischemia.
Visual hallucinations were the initial complaints in a patient with a posterior cerebral artery occlusions who fell and sustained bilateral subdural hematomas. In addition to poor vision, the patient experienced formed visual hallucinations of the epileptic type in the hemianopic field. The hemianopia was dense with macular sparing. CAT scans, which were done pre- and postoperatively, showed no abnormalities in the temporal and occipital lobes to explain the "epileptic visual hallucinations" and macular sparing. The NMR scan showed low-density changes in those areas. At the time that the NMR scan was done, most of the patient's deficits, including the hemianopia and hallucinations, had resolved.
