Regional cerebral blood flow in diagnosis of childhood onset partial epilepsy.
|
| Abstract |
We compared regional cerebral blood flow assessed by [123I]N-isopropyl-p-iodoamphetamine (IMP) single-photon emission tomography (SPECT) with magnetic resonance imaging (MRI), computed tomography (CT) and interictal surface electroencephalography (EEG) to evaluate its diagnostic potential in 24 patients with partial seizures with onset in childhood. Focal low uptake areas were observed on SPECT scans of 18 patients and were presumed to represent epileptogenic areas in 17. MRI revealed an abnormality in 12 and CT in 6 patients, and all organic lesions showed SPECT abnormalities, too. Six patients without focal structural abnormalities showed regional perfusion deficit on SPECT. Routine scalp EEG revealed an epileptic focus in 17 patients and three of them showed discordant results between SPECT and EEG, which suggested more serious brain disorders. In two patients without EEG localization only SPECT showed focal abnormalities in the probable epileptic area. [123I]IMP-SPECT was useful in locating the epileptic focus, particularly during the early period after the onset of partial seizures when the EEG gave inconclusive results.
