Case Presentation: Recurrent Steroid-Induced Hypokalemic Periodic Paralysis Mimicking Acute Neuropathy

Abstract

This case report details the presentation of a 34-year-old male with acute onset bilateral lower extremity weakness, diagnosed as hypokalemic periodic paralysis (HPP) triggered by recurrent intramuscular dexamethasone administration. The patient, with a history of frequent steroid injections for upper respiratory infections, presented with profound lower limb weakness (3/5) and a serum potassium level of 2.7 mmol/L. Rapid correction of hypokalemia led to significant neurological recovery. Extensive neurological imaging and initial electromyography (EMG) were concerning for peripheral neuropathy, but follow-up EMG normalized completely after potassium repletion and cessation of the steroid trigger. This case underscores HPP as a crucial, reversible differential in acute weakness, highlights the significant risk posed by intermittent steroid use, and demonstrates the potential for transient electrodiagnostic abnormalities that may mislead initial diagnosis.
