There are only a few reports in the literature on electroencephalographic findings in cases of arteriovenous anomalies of the brain, and most such reports are based on relatively small series or isolated cases. The present study is only part of a broader review, to appear in consecutive publications, of the clinical, radiologic, and surgical aspects of 51 cases of cerebral angioma seen at the Mayo Clinic between 1930 and 1954. In this study an attempt is made to consider the value of the electroencephalogram as a preliminary test and screening procedure in the diagnostic evaluation of arteriovenous anomalies. The degree and type of electroencephalographic abnormalities are considered in relation to type, extent, and location of the underlying lesion and are correlated with the duration and kind of certain outstanding clinical features.

MATERIAL AND METHODS  For this study all electroencephalographically recorded cases of arteriovenous malformation of the brain registered at the
