结核性脑膜炎与隐球菌性脑膜炎的病因和治疗完全不同,预后也有明显差异,而两者临床表现相似,常导致隐球菌性脑膜炎误诊为结核性脑膜炎。隐球菌性脑膜炎病死率高,早期治疗疗效明显优于晚期,故临床鉴别诊断非常重要。本研究旨在找出两者的不同点,供临床诊断参考,以减少其误诊率。 Tuberculous meningitis and cryptococcal meningitis etiology and treatment are completely different, the prognosis is also significantly different, and the clinical manifestations of the two similar, often lead to cryptococcal meningitis misdiagnosed as tuberculous meningitis. Cryptococcal meningitis high mortality, early treatment was significantly better than the late treatment, so the differential diagnosis is very important. This study aims to find the difference between the two for clinical diagnosis of reference to reduce the misdiagnosis rate.
