弓形虫感染的脑电与头颅CT对比观察

Comparative Study of EEG and Cephalic CT in Patients with Toxoplasmosis

弓形虫病（ｔｏｘｏｐｌａｍｏｓｉｓ）是由刚地（ｇａｎｄｉ）弓形虫引起的一种寄生虫病。世界各地广泛分布，中国从１９５７年开始报告临床病例，但脑电改变报告不多。本文拟就探讨其脑电及ＣＴ的变化．所有２４例病人均经间接血凝试验（ＩＨＡ）检查明确诊断，并做脑电检测及头颅ＣＴ扫描。结果发现２４例脑电全部为程度不等的异常，异常率１００％。头颅ＣＴ扫描２０例中有８例阳性病灶，阳性率４０％。结论是系统症状的弓形虫感染者其脑电异常率明显高于ＣＴ。脑电特殊检查法——蝶骨电极会进一步提高其阳性率，从而明确神经系统是否受侵及侵犯的程度。

Toxoplasmosis is a kind of parasite disease,by Toxoplasmosis gondii, distributed all over the world.Since 1957,there were some clinical case reports,but the one related with EEG changes were rare.This study will discuss its EEG and CT change.All 24 patients were clearly diagnosed by indirect hemagglu tination(IHA).Meanwhile,EEG and cephalic CT were examined.The different abnormal changes of EEG were present in all 24 patients,the abremal rate was 100%.Among the cephalic CT examination in 20 cases,there were only 8 cases with positive pathologic site.The positive rate was 40%.The abnormal rate of EEG in toxoplasmosis patients with neurological system was obviously higher than that of cephalic CT.The special EEG examination method sphenoid potential can raise its positive rate.Therefore,it can be used to determine whether or not the neurological system is invaded,or what degree it is invaded.
