貌似脑炎的脑肿瘤7例临床分析

Cerebral tumor very similar to encephalitis(7 cases clinical analysis)

目的 :探讨貌似脑炎的脑肿瘤临床特点 ,提高对本病的诊断率。方法 :观察 7例病人发病前后的表现和脑电图、血常规、脑脊液、头 CT、脑血管造影等辅助检查的改变 ,分析探讨本病的特点。结果 :早期脑肿瘤可因感冒加重症状而诱发。额颞叶肿瘤最易出现精神症状。某些脑肿瘤的脑脊液可以出现类似脑炎改变 ,这是临床易误诊的主要原因之一。脑血管造影、脑电对脑肿瘤均有诊断意义 ,在没有 CT条件下应做为辅助检查 ,虽然头 CT对脑肿瘤的诊断意义已肯定 ,但肿瘤极早期可因瘤体太小而 CT检查呈阴性结果。结论 :部分脑肿瘤临床表现酷似脑炎 ,提示临床医生在观察治疗中要做及时、全面的复查 ,以免误诊。

Objective To investigate the clinical characteristics of cerebral tumor similar to encephalitis in manifestation in order to heighten the diagnostic rate.Methods By means of observations on seven patients before and after treatment the changes in clinical presentations,EEG,blood routine,CSF,cerebrocranical CT,cerebroangiog raphy,and other adjuvant examinations were analysed meanwhile the characteristics of this disease were investigated.Results The symptomatic onset of early cerebral tumor could be induced by common cold and the mental symptoms were most freguently occured in tumors of frontotemporal lobe.The CSF variations in some patients with cerebral tumor might be similar to those in encephalitis so that it became one of main reasons to be misdiagnosed,The cerebroangiography and EEG passessed significance for diagnosis of cerebral tumor so they could be as adjuvant measures nuder the setuations not having CT.Although the value of cerebrocranical CT in diagnosis of cerebral tumor was certain the result of CT could be negative sometimes in very early stage becouse the body of tumor was too small to diagnose.Conclusions The presentations of some cerebral tumor are very similar to encephalitis so that clinically it suggests that physicians in observation and therapy should reexamine promptly and overall in order to avoid misdiagnosis.
