Bacterial meningitis is an acute, life-threatening infection characterized by severe inflammation of the leptomeninges and the subarachnoid space surrounding the brain and spinal cord Patients typically present with rapid clinical deterioration marked by the classic triad of high fever, nuchal rigidity, and altered mental status, often accompanied by severe headache, nausea, and photophobia

Bacterial meningitis is an acute, life-threatening infection characterized by severe inflammation of the leptomeninges and the subarachnoid space surrounding the brain and spinal cord Pathophysiologically, bacterial invasion breaches the blood-brain barrier—typically following bacteremic dissemination or direct contiguous spread—initiating a marked host immune response, neutrophil infiltration, increased intracranial pressure, and cerebral edema
