应用 CT 有助于发现晚发性癫痫,但是否将其作为常规检查,目前意见尚不一致。作者分析250例晚发性癫痫的 CT 检查,讨论 CT 检查的有效性及其检查结果与临床表现、脑电图(EEG)和可能获得的组织学诊断之间的关系。这些患者平均发病年龄为52(22～88)岁。结果如下。一、CT 检查:CT 异常127例(50.8%),其中广泛性脑萎缩48例(19.2%),脑肿瘤41例(16.4%),脑梗塞22例(8.8%),多发性钙化5例(2%),局限性脑萎缩和血肿各4例(3.2%),血管瘤、蛛网膜囊肿、
The application of CT helps to detect late epilepsy, but whether it is used as a routine examination, the current opinion is not the same. The authors analyzed CT findings in 250 patients with late-onset epilepsy and discussed the validity of the CT examination and the relationship between the results and the clinical presentation, electroencephalogram (EEG), and possible histologic diagnosis. The average age at onset of these patients was 52 (22-88) years. The result is as follows. First, the CT examination: CT abnormalities in 127 cases (50.8%), including extensive brain atrophy in 48 cases (19.2%), brain tumors in 41 cases (16.4%), cerebral infarction in 22 cases (8.8%), multiple calcifications in 5 cases 2%), 4 cases of localized brain atrophy and hematoma (3.2%), hemangiomas, arachnoid cysts,
