Abstract

Posterior reversible encephalopathy syndrome (PRES), also known as reversible posterior leukoencephalopathy syndrome (RPLS), is most often associated with hypertensive emergencies and is characterized by seizures, mental status changes and visual disturbances. We report a case of a previously healthy young man who developed multiorgan failure and transient cortical blindness following ingestion of a performance-enhancing ephedra-based supplement. Neuroimaging findings confirmed the clinical suspicion of PRES. Radiographic abnormalities and neurologic dysfunction subsequently resolved with correction of his systolic blood pressure. This case emphasizes the need for prompt treatment and consideration of toxic ingestions in patients presenting with hypertension-related end-organ dysfunction.
