V. Brain Abscesses

D. Spinal Fluid Changes

Usually increased pressure, relatively few cells,  mildly elevated white cell count and protein level, normal glucose (reactive meningitis).

E. Clinical presentation:

Progressive focal deficits, general signs of increased intracranial pressure.

F. Complications:

Space occupying mass and edema with herniation; necrosis of functional tissue. Abscesses may rupture into ventricles or subarachnoid space, resulting in ependymitis and meningitis. Seizures occur in approximately 50% of cases.
