Fulminating Hyperpyrexia
📋Overview
Fulminating hyperpyrexia is a legacy term referring to an extremely high and rapidly developing fever, often exceeding 41°C (105.8°F). It is not a distinct diagnosis but rather a descriptive phrase historically used to denote severe hyperthermia associated with critical illness. Modern terminology focuses on the underlying causes of such extreme fever, including severe infections (e.g., sepsis), heat stroke, neuroleptic malignant syndrome, or other hypermetabolic states.
