Purulent meningitis is induced by purulent bacterial infection, manifesting as turbid cerebrospinal fluid with a large amount of cells especially white blood cells, increased protein level and low sugar and chloride content.
The MRI results of the two groups: The MRI results demonstrated that, the positive rate of the observation group was 96.05%; the positive rate of the tubercular meningitis group and the cryptococcal meningitis group was both 100%; the positive rate of the viral meningitis group (Fig.1) and the purulent meningitis group was 90.48% and 92.86% respectively.
The examination results of LDH, CK and LA between the two groups: The examination results of the cerebrospinal fluid demonstrated that, the LDH concentration of the tubercular meningitis group was the highest, the CK concentration of the purulent meningitis group was the highest, and the LA concentration of the tubercular meningitis group and purulent meningitis group was higher than the other two groups.
The diagnostic efficacy of MRI in combination with cerebrospinal fluid analysis in diagnosing CNSI: The sensitivity of MRI in combination with cerebrospinal fluid analysis in diagnosing tubercular meningitis, viral meningitis and cryptococcal meningitis was higher than that in diagnosing purulent meningitis. The specificity and accuracy of MRI in combination with cerebrospinal fluid analysis in diagnosing viral meningitis, purulent meningitis and tubercular meningitis was much higher than that in diagnosing cryptococcal meningitis (Table-III).
By comparing the initial clinical diagnoses in our study with the bacterial meningitis laboratory results, we found that some clinical diagnoses (e.g., meningococcal meningitis and purulent meningitis) were most likely to represent cases with a confirmed bacterial cause.

In total we found 27 cases of Hib meningitis, 5 of whom died, and 81 cases of purulent meningitis. Based on an efficacy of 44 per cent against purulent meningitis and full vaccination, 36 cases of meningitis would have been prevented.
