Inter-modality comparisons of seizure focus lateralization in complex partial seizures

Abstract: Anterior temporal lobectomy offers a high chance of seizure-free outcome in patients suffering from drug-refractory complex partial seizure (CPS) originating from the temporal lobe. Other than EEG, several functional and morphologic imaging methods are used to define the spatial seizure origin. The present study was undertaken to compare the merits of fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET), magnetic resonance imaging (MRI) and single-voxel proton MR spectroscopy (MRS) for the lat… Show more

“…Such a wide range seemingly results from differences in patients' characteristics, investigated temporal lobe regions, spectroscopy techniques used, and applied diagnostic criteria [14,26,29]. It should be noted that even in patients with bilateral MTLE, that is if more than 20% of the ictal epileptiform activity is originating from both temporal lobes [7,19], the spectroscopic abnormalities are lateralized in 80% of cases [19,20]. Possible spectroscopic identification of the epileptogenic zone in such cases might be extremely useful for determination of the surgical indications in patients with bitemporal seizure origin.…”

“…Since contralateral MRI abnormality is frequently absent, it was suggested that spectroscopic imaging might detect regional neuronal alterations before development of the identifiable structural changes [17]. Presence of contralateral metabolic abnormalities decreases the diagnostic accuracy of 1 H-MRS in temporal lobe epilepsy and the rate of false lateralization of the epileptogenic zone varies from 2% to 20% [9][10][11]13,16,[19][20][21][25][26][27]29]. In concordance with our results, Kantarci et al [26] and Suhy et al [28] reported that all patients in their series with 1 H-MRSbased lateralization of the epileptogenic zone to the side opposite to that of surgery had excellent postoperative seizure outcomes.…”
