Abstract

To date, there have been no reports of paroxysmal sympathetic hyperactivity syndrome (PSHS) associated with cerebral fat embolization. We describe the case of a young male who developed acute brain injury and acute hypoxemic respiratory failure secondary to significant fat embolization following a traumatic femur injury. Our patient demonstrated episodes of significant hypertension, tachycardia, fever and extensor posturing. Extensive evaluation lead to the diagnosis and appropri-ate treatment for PSHS. Ultimately, the patient went on to have a good neurologic recovery after a prolonged hospitalization. We will discuss PSHS diagnostic criteria, pathophysiology and treatment options. This diagnosis should be considered in all brain-injured patients with paroxysms of autonomic instability and abnormal movements.
