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 features of brain tumors that look like encephalitis and improve the diagnosis rate of this disease. Methods: Seven patients were observed before and after the onset of the performance and electroencephalogram, blood, cerebrospinal fluid, head CT, cerebral angiography and other auxiliary examination changes analyzed to explore the characteristics of the disease. Results: Early brain tumors can be induced by the aggravation of symptoms. Frontal temporal lobe tumors most likely to have mental symptoms. Cerebrospinal fluid in some brain tumors may show similar changes in encephalitis, which is one of the main causes of clinical misdiagnosis. Cerebral angiography, EEG have diagnostic significance in brain tumors, in the absence of CT conditions should be done as an auxiliary examination, although the head CT diagnosis of brain tumors have been affirmed, but very early tumor because the tumor is too small and CT examination Negative result. Conclusion: The clinical manifestations of some brain tumors resemble those of encephalitis, suggesting that clinicians should make timely and comprehensive reviews during the observation and treatment to avoid misdiagnosis.
