Abstract:
A patient developed visual hallucinations following a left-sided cerebrovascular accident (CVA). Brain SPECT using Tc-99m HMPAO demonstrated increased perfusion at the biparieto-occipital lobes. Following antiepileptic medication, repeat brain SPECT showed interval decrease in perfusion in the same areas with the symptomatic relief of hallucinatory episode. While it is possible that the interval decrease is due to natural resolution, the authors believe that it is likely due to drug treatment.
