目的：本文旨在探讨诊断不典型结核性脑膜炎的方法，以避免误诊，减少死亡率。方法：回顾性分析了２４例结核性脑膜炎的临床资料、ＣＴ表现及误诊原因。结果：２４例患者中早期临床表现多无特异性，与其它颅脑感染难以鉴别，脑脊液等实验室指标及ＣＴ改变均不典型，反复复查可出现典型表现。在诊断过程中，必须从该病的不同阶段出发，综合分析，才能得以确诊。结论：结核性脑膜炎极易误诊，正确诊断是治愈患者的关键因素。
Objective: This article aims to explore the diagnosis of atypical tuberculous meningitis in order to avoid misdiagnosis and reduce mortality. Methods: A retrospective analysis of 24 cases of tuberculous meningitis clinical data, CT findings and misdiagnosis reasons. Results: The early clinical manifestations in 24 patients were mostly nonspecific. It was difficult to identify with other craniocerebral infections. Laboratory tests such as cerebrospinal fluid (CSF) and CT changes were not typical. The recurrent findings were typical. In the diagnosis process, we must proceed from the different stages of the disease, a comprehensive analysis to be diagnosed. Conclusions: Tuberculous meningitis is easily misdiagnosed, and correct diagnosis is the key factor to cure patients.
