Hemodynamic and neurological presentations of invasive meningococcal disease in adults: a nationwide study across 100+ French ICUs : The RETRO-MENINGO study.

Purpose: Invasive meningococcal disease (IMD) is a rare but potentially fatal infection caused by Neisseria meningitidis. In adults requiring admission to intensive care unit (ICU), IMD typically presents with two distinct clinical presentations: neurological (meningitis) and hemodynamic (sepsis). These presentations are often conflated, despite the differences in pathophysiology and outcome.
