Quantitative EEG findings of a temporal lobe abnormality not detected by magnetic resonance or SPECT imaging in a patient with dementia.

摘要

The last three decades have seen significant advances in structural neuroimaging techniques such as computerized tomography and magnetic resonance imaging. These seem to have surpassed EEG as modalities for the identification of focal CNS lesions. Reported here is the case of a patient with a temporal lobe lesion not evident with magnetic resonance imaging or single photon emission computerized tomography but detected by EEG and positron emission tomography. EEG, particularly quantitative EEG, remains a valuable tool for the demonstration of the degree of dysfunctional changes associated with a cerebral lesion.
