The CSF analysis report of a 30-year-old man with meningitis reveals the following findings:
CSF opening pressure = 100 mm H2O
WBC count = 80 per mm3
Cell differential = Predominance of lymphocytes
Protein = 75 mg/dL
CSF-to-serum glucose ratio: = normal to significantly decreased

Question

Quizplus · Accepted Answer

Viral meningitis is usually manifested by a normal CSF opening pressure, a WBC less than 100 per mm 3, normal to elevated protein, and normal CSF-to-serum glucose ratio. A predominance of lymphocytes distinguishes viral meningitis from bacterial meningitis, which is predominant with PMNs. Options C and D have low CSF-to-serum glucose ratio.
