We report a case of a previously healthy early adolescent female who presented with meningococcal meningitis. While in hospital, she had marked neurologic deterioration with clinical herniation from malignant cerebral oedema. She was transferred to a neurocritical care centre where she underwent invasive intracranial pressure (ICP) and brain tissue oxygen (PbtO2) monitoring. Early in her course, she demonstrated a compete absence of autoregulation, with pressure passive cerebral blood flow. As a result, maintaining a mean arterial pressure between 50 mm Hg and 60 mm Hg, which ensured adequate cerebral oxygenation, while avoiding increases in ICP. Although her course was initially complicated by bilateral optic neuropathy, she has subsequently made a full neurologic recovery and is now undertaking postsecondary education. This case highlights that access to specialist neurocritical care, guided by neurophysiologic monitoring of ICP and PbtO2, may help improve outcomes, even among those patients with catastrophic cerebral oedema from bacterial meningitis.
