Value of Repeat Brain MRI in Children with Focal Epilepsy and Negative Findings on Initial MRI
OBJECTIVE To evaluate the value of repeat brain magnetic resonance imaging (MRI) in identifying potential epileptogenic lesions in children with initial MRI-negative focal epilepsy. MATERIALS AND METHODS Our Institutional Review Board approved this retrospective study and waived the requirement for informed consent. During a 15-year period, 257 children (148 boys and 109 girls) with initial M...
متن کاملClinical factors predict surgical outcomes in pediatric MRI-negative drug-resistant epilepsy
PURPOSE Lack of a potentially epileptogenic lesion on brain magnetic resonance imaging (MRI) is a poor prognostic marker for epilepsy surgery. We present a single-center series of childhood-onset MRI-negative drug-resistant epilepsy (DRE) and analyze surgical outcomes and predictors. METHODS Children with MRI-negative DRE who had resective surgery from January 2007 to December 2013 were ident...
متن کاملHippocampal T2 hyperintensities on 7 Tesla MRI☆
Hippocampal focal T2 hyperintensities (HT2Hs), also referred to as hippocampal sulcal cavities, are a common finding on Magnetic Resonance (MR) images. There is uncertainty about their etiology and clinical significance. In this study we aimed to describe these HT2Hs in more detail using high resolution 7 Tesla MR imaging, addressing 1) the MR signal characteristics of HT2Hs, 2) their occurrenc...
متن کاملSurgical outcome in PET-positive, MRI-negative patients with temporal lobe epilepsy.
PURPOSE Fluorodeoxyglucose positron emission computed tomography (FDG-PET) hypometabolism is important for surgical planning in patients with temporal lobe epilepsy (TLE), but its significance remains unclear in patients who do not have evidence of mesial temporal sclerosis (MTS) on magnetic resonance imaging (MRI). We examined surgical outcomes in a group of PET-positive, MRI-negative patients...
