Electroencephalographic findings of brain granuloma-in correlation with brain C.T. findings

The authors analyzed the electroencephalgraphic findings of 36 patients diagnosed as brain granuloma which are confirmed by C.T. scan. More often EEG records were read as “within normal limit” in cases which had less frequent attacks of clinical seizure. Electroencephalographic records showed polymorphic delta activity in 33. 3% of patients involving cerebral white matter and depressed background amplitude in only 13.9% involving cerebral cortex. This incidence of abnormal electroencephalographic findings in brain granuloma isrelatively low compared to that of rapid growing brain tum or The focal abnormalities of electroencephalography were found in 61.6% of patients. Therefore we concluded the serial recordings of electroencephalography are relatively usefulmethods in evaluating the prognosis of brain granuloma
