Paroxysmal Sympathetic Hyperactivity Syndrome in the Setting of Fat Emboli Syndrome Secondary to Polytrauma.

Paroxysmal sympathetic hyperactivity (PSH) syndrome is a potentially life-threatening complication after traumatic brain injuries that results from a massive release of catecholamines in the brain. Fat embolism syndrome (FES) is a complication of long bone fractures that results in cerebral or pulmonary fat emboli. We describe PSH in the setting of cerebral FES in an adolescent female following polytrauma secondary to a motor vehicle collision to highlight the importance of rapid diagnosis and treatment of this rare complication.
