A. Lymphocytic pleocytosis, low sugar, high protein
B. Lymphocytic pleocytosis, low sugar, low protein
C. Lymphocytic pleocytosis, high sugar, low protein
D. Neutrophilic pleocytosis, low sugar, high protein

(Modified repeat question – AIPGMEE 07 MK q176 – In the original question, the clinical scenario was not included – instead, the diagnosis was given and the CSF features were asked)

Correct answer : A. Lymphocytic pleocytosis, low sugar, high protein

  • Elevated CSF pressure
  • Increased protein (10-500mg/dl)
  • Decreased glucose (20-40mg/dl)
  • Lymphocytic pleocytosis (10-500 cells / microlitre)
