RESUMEN
It is believed that migrainous aura is correlated with cortical spreading depression and spreading benign oligemia. A 54-year-old female with migraine with aura presented with left hemianopia preceding pulsating headache. Perfusion-weighted images revealed delayed contrast arrival to the right occipital lobe and nearly normal relative cerebral blood volume images, indicating benign oligemia. Follow-up perfusion-weighted images revealed resolution of the perfusion abnormalities. We report herein a case of migraine with aura presenting with reversible delayed perfusion in the right occipital lobe on perfusion-weighted images.

We report a monozygotic twins with temporal lobe epilepsy, almost concordant in the onset time of firt seizure, lateralization and localization of epileptiform discharges. Partial seizures with secondarily generalized seizure occurred 15 days apart. EEG showed frequent spike-slow wave complexes on the right temporal area but the findings of brain MRI were normal in both. Past medical, delivery, developmental and family history were unremarkable. They had no physical and mental handicaps, and any other underlying causes of epilepsy. They have been on monotherapy with seizure free, although follow up EEG showed frequent spike-slow wave complexes after medication. As seizures developed simultaneously, the localization and lateralization of epileptiform discharges were concordant in our monozygotic twins, we suggest that genetic factor might be the most probable etiology of epilepsy in our cases but needs to be elucidated.

Different types of aphasia resulting from stroke, as well as their anatomical correlates, are well characterized. In contrast, the literature on ictal aphasia is relatively scant. A 58-year-old woman had 4 times of transient motor aphasia. No other behavioral abnormalities and focal sensorimotor neurological deficits were revealed. Brain MRI showed a small meningioma at the left sphenoid ridge. Electroencephalogram showed occasional sharp waves on the left inferior frontal area. We report a rare case of ictal aphasia associated with meningioma.
