Acute Pyogenic Meningitis true is/are: 

a. Purulent exudates within leptomeninges 
b. CSF cloudy with PMN 
c. Spreads to ventricle 
d. Causes ventricular enlargements 
e. CSF chloride increased

Ans (A) Purulent exudates within leptomeninges , (B) CSF cloudy with PMN (C) Spreads to ventricle , (D) Causes ventricular enlargements ,

• In acute pygenie meningitis CSF becomes cloudy and sometimes frankly purulent Exudates are evident in the leptomeninges over the surface of the brain. Exudates varies in location e.g. for H influenzae — usually basal for Pneumococcal - cerebral convexities When meningitis is fulminant, the inflammation may extend to ventricles, producing ventriculitis.

• Neutrophil fills entire subarchnoid space in severe cases.

(A) Proteus vulgaris ; (B) Chlamydia
