title: Cortical dysplasia, temporal atrophy, mental retardation, dysmorphic facies, and partial epilepsy: an EEG and dynamic susceptibility contrast (DSC) MRI study in a new possible genetic syndrome.
abstract: We report the case of a 24-year-old female with partial epilepsy, mental retardation, and dysmorphic facies. In EEG, a high spiking rate (HSR) was evident with abnormalities in the right frontal region. Morphological MRI showed a left temporo-mesial sclerosis and a cortical dysplasia localized in the right frontal cortex. Dynamic susceptibility contrast (DSC) MRI showed hyperperfusion in right frontal region and hypoperfusion in left fronto-temporal region. Left fronto-temporal hypoperfusion is consistent with temporo-mesial sclerosis. Right frontal hyperperfusion is related to the cortical dysplasia area with HSR. HSR may resemble both electroencephalographic and perfusional ictal pattern. DSC MRI is useful in the evaluation of regions involved in the genesis of ictal and interictal epileptiform activity. Furthermore, we hypothesize that our patient would be affected by a new possible genetic syndrome.
