Abstract:
Objective To investigate the imaging features and laboratory detection characteristics of tuberculous meningitis (TBM ) for achieving the purpose of early diagnosis and treatment.Methods Seventy-four patients with TBM in First Affiliated Hospital of Xi'an Jiaotong University from January 2013 to December 2015 were selected as the experimental group and 80 patients of non-TBM as the control group.All cases were performed ADA ,TB-DNA and acid-fast bacilli smear detection in cerebrospinal fluid ,and at the same time ,which was combined with tuberculous infection T-SPOT.TB test and compared with the results of ima-ging examination.Then the application values of various examinations were compared.Results The sensitivity of ADA ,TB-DNA , acid-fast bacilli smear ,T-SPOT.TB and the imaging examination for 74 patients with TBM were respectively 64.86% (48/74) , 33.78% (25/74) ,75.68% (56/74) ,10.81% (8/74) and 54.05% (40/74).The specificity were respectively 75.00% (60/80) , 100.00% (80/80) ,58.75% (47/80) ,100.00% (80/80) and 91.25% (73/80).Conclusion The difference in imaging and laboratory test indicators has a certain guiding significance for TBM clinical diagnosis.Except for clinical routine detection ,other detections should be perfected as far as possible ,conducting the comprehensive analysis can improve the accuracy of diagnosis.
