26 cases with frontal intermittent rhythmic delta activity (FIRDA) in the EEG are presented and compared to the corresponding results in computerized axial tomography (CT) of the brain. Selection was undertaken randomly without reference to special diagnostic aspects. Only 3 cases showed a deviation of the cerebral midline structures in the CT, because of a cerebral tumor. No deviation of the midline structures in the CT could be found in the other 23 cases, where FIRDA was the outstanding finding in the EEG. Thus, the conclusion may be drawn that FIRDA in the EEG is by no means indicative of subcortical lesions, especially tumors, with alteration of midline structures.
本文报告了26例脑电图显示额部间歇性节律性δ活动（FIRDA）的病例，并将其与脑部计算机断层扫描（CT）的相应结果进行了比较。选择过程是随机进行的，未参考特殊诊断方面的因素。仅3例因脑肿瘤在CT上显示脑中线结构偏移。在其他23例中，CT未发现中线结构偏移，而脑电图中FIRDA是突出表现。因此，可以得出结论，脑电图中的FIRDA绝不能提示存在伴有中线结构改变的皮质下病变，尤其是肿瘤。
