Bilateral Lower Extremity Paralysis in a Caucasian Male Presenting to the Emergency Department

Reported is a case of a 39-year-old Caucasian man who presented to the emergency department with sudden onset bilateral lower extremity paralysis after consuming a large amount of carbohydrates and alcohol. A CT, MRI, and lumbar puncture were performed with negative results; lab results showed hyperthyroidism and hypokalemia. The patient was diagnosed with thyrotoxic periodic paralysis. In a patient presenting with sudden onset paralysis and hypokalemia, the emergency physician should include thyrotoxic periodic paralysis in the differential diagnosis and focus on treating and working up the hypokalemia instead of the paralysis.
