Triphasic waves in a patient with glioblastoma multiforme.
A 57-year-old woman with biopsy proven glioblastoma multiforme with greater left-sided involvement, presented with subacute right hemiparesis. Her EEG showed triphasic waves with a left-sided predominance. Possible metabolic causes of triphasic waves were excluded. The association between triphasic waves and primary brain tumor is extremely rare, and the pathogenesis unknown.
