On physical exam, pain is elicited upon passive flexion of the patients neck. A CT scan shows ventricular enlargement. A CD4 count is 57 cellsμL blood. A lumbar puncture is performed with the following findings:Cerebrospinal fluid:Opening pressure: 210 mmH2OGlucose: 32 mgdLProtein: 204 mgdLIndia ink stain: PositiveLeukocyte count and differential:Leukocyte count: 200mm3Lymphocytes: 100Red blood cell count: 2What is the next best step in therapy??
