Computed tomography and EEG in patients without focal neurologic findings

We studied 136 patients without focal neurologic findings by EEG and computed tomographic (CT) scanning. Six patients (4.4%) had focal CT lesions. All six had abnormal EEGs, and in four the EEG findings were focal. The initial complaint did not influence the yield of focal CT lesions. The findings suggest that neurologic examination and EEG can be used to screen for focal CT abnormalities.
