Myasthenic crisis is a severe complication of myasthenia gravis (MG) characterized by respiratory failure. This case report presents a 24-year-old woman admitted with respiratory distress, eventually diagnosed with myasthenic crisis triggered by COVID-19. Initial symptoms included throat pain and dysphagia with no evident pathology. Elevated acetylcholine receptor antibodies confirmed MG.
