A 30-year-old male is admitted to the hospital with severe headache, neck stiffness and photophobia. A lumbar puncture is performed, and the cerebrospinal fluid (CSF) analysis reveals the following: Appearance: Cloudy White Blood Cell Count: 800 cells/mm³ (0-5 cells/mm³) Protein Level: 200 mg/dL (15-45 mg/dL) Glucose Level: 30 mg/dL (50-80 mg/dL) Based on these findings, which of the following conditions is most likely responsible for the patient’s presentation?
