Abstract: Objective To analyze the correlation between MRI imaging findings and clinical outcomes in patients with intracranial tuberculosis.Methods 162 cases of intracranial tuberculosis diagnosed in the Third People's Hospital of Shenzhen from August 2011 to December 2016 were reviewed. Their MRI findings and clinical outcomes were analyzed retrospectively.Result The imaging findings and clinical outcomes were as below: 67 cases of meningeal tuberculosis, the clinical cure rate was 83.6% (56/67); 52 cases of brain parenchymal tuberculosis, the clinical cure rate was 71.2% (37/52); 43 cases of mixed intracranial tuberculosis, the clinical cure rate was 65.1%. (28/43), the difference between the three groups was not statistically significant (χ²=5.231, P=0.073). The imaging findings of complication were as below: 17 cases of cerebral infarction, the clinical cure rate was 58.8% (10/17); 18 cases of hydrocephalus, clinical cure rate was 50.0% (9/18); 4 cases of cerebral infarction and hydrocephalus, clinical cure rate was 75.0 %(3/4). The difference between the three groups was not statistically significant (χ²=0.888, P=0.726). There were 123 cases of imaging without complications, the clinical cure rate was 80.5% (99/123) and 39 cases had complications, the clinical cure rate was 56.4% (22/39). The difference between the two groups was statistically significant (χ²=9.081), P=0.003).Conclusion The imaging complications of intracranial tuberculosis were significantly correlated with clinical cure rate, this finding may provide a certain reference value for the evaluation of clinical outcomes.
