title: Severe neurologic manifestations of fat embolism syndrome in a polytrauma patient.
abstract: Fat embolism syndrome (FES) is most commonly diagnosed when the classic triad of respiratory difficulty, neurologic abnormalities, and petechial rash are present in the appropriate clinical setting. Neurologic manifestations can range from headache, confusion, and agitation to stupor and, less commonly, coma. This article describes a case of FES with severe neurologic sequelae without typical pulmonary involvement in a polytrauma patient with proximal humerus and L1 compression fractures. The case highlights the importance of considering FES in the patient with deteriorating mental status in the setting of multiple fractures, particularly in the absence of other characteristic clinical findings. Early recognition allows for the anticipation of other complications, such as respiratory distress and the potential need for mechanical ventilation.
