Abstract:
Objective To summary the electroencephalography characteristics of temporal lobe ganglion glioma (GG),and explore the role of electroencephalogram in diagnosis and treatment of temporal lobe GG.Methods Retrospective analysis of clinical features,diagnosis and treatment of 24 patients with temporal lobe GG,admitted to our hospital from September 2008 to September 2015,was performed.The temporal lobe GG electroencephalography features were accepted focused research.Results Break electroencephalography showed that:abnormal discharge of lesions in store area and contralateral brain regions was noted in 17 patients (70.8％).Episodes electroencephalography showed that:10 patients (41.6％) could be conformed that discharge was originated from the side of temporal sphenoid.Intra-operative electroencephalography showed that the medial temporal lobe in 22 patients (91.7％) had low amplitude fast wave with high reflection of sharp wave or spike wave;the temporal lobe cortex in 23 patients (95.8％) had high reflection of sharp wave or spike wave.The patients were followed up for one to 8 years.Engel's grading I was noted in 19 patients (79％),including 11 gradually stopped taking antiepileptic drugs after three years of free seizure;Engel's grading Ⅱ was noted in 5 patie nts (79％),and antiepileptic drugs were taken.Conclusions The temporal lobe GG electroencephalography shows that abnormal discharge is sharp and slow waves are noted,which are easy to generalize to other brain regions and the contralateral side.Monitoring of electroencephalography during operation can record the abnormal discharge around and in the center of GG with spike wave rhythms.Cortical electroencephalogram and deep electrode monitoring can help to determine the lesion and the around range of epilepsy,which can guide the operation and improve the control of seizures.
