Epileptic polyopia with right temporal lobe epilepsy as studied by FDG-PET and MRI: a case report.
Polyopia is one of rare, visual hallucinations. A 61-year-old man suffered from daily episodes of polyopia and generalized convulsions, and he was diagnosed as right temporal lobe epilepsy. MRI revealed right amygdalar swelling. FDG-PET showed hypometabolism in the right anterior temporal and the mesial occipital areas. Polyopia is thought to be caused by dysfunction of updating process of visual information in the visual association cortices. It was most likely that, in this patient, both mesial temporal and ipsilateral occipital areas were responsible for manifesting epileptic polyopia, as ictal onset zone and symptomatogenic zone, respectively.
