Vaka Sunumu: Akut Nöropatiyi Taklit Eden Tekrarlayan Steroid Kaynaklı Hipokalemik Periyodik Paralizi

Abstract

Bu vaka raporu, tekrarlayan intramüsküler deksametazon uygulamalarının tetiklediği hipokalemik periyodik paralizi (HPP) tanısı konulan, akut başlangıçlı bilateral alt ekstremite güçsüzlüğü şikayeti ile başvuran 34 yaşındaki bir erkek hastanın kliniğini ayrıntılı olarak sunmaktadır. Üst solunum yolu enfeksiyonları nedeniyle sık sık steroid enjeksiyonu öyküsü olan hasta, şiddetli alt ekstremite güçsüzlüğü (3/5) ve 2,7 mmol/L serum potasyum düzeyi ile başvurmuştur. Hipokaleminin hızlı bir şekilde düzeltilmesi, önemli ölçüde nörolojik iyileşmeye yol açmıştır. Kapsamlı nörolojik görüntüleme ve ilk elektromiyografi (EMG) bulguları periferik nöropati şüphesini doğurmuş olsa da, potasyum replasmanı ve steroid tedavisinin kesilmesinden sonra takip EMG’si tamamen normale dönmüştür. Bu vaka, akut kuvvet kaybında HPP’nin önemli ve geri dönüşümlü bir ayırıcı tanı olduğunu vurgulamakta, aralıklı steroid kullanımının oluşturduğu önemli riski ortaya koymakta ve ilk tanıyı yanıltabilecek geçici elektrodiagnostik anormalliklerin olasılığını göstermektedir.

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.
