Abstract
Pseudomyotonia is a syndrome characterized by progressive muscle stiffness, weakness, myokymia, hyperhydrosis, and wasting of muscle. It especially affects the distal aspect of the extremities. The electromyogram is characteristic, and shows continuous muscle activity at rest. We discuss a case that is believed to be the first recorded instance of pseudomyotonia complicated by airway obstruction secondary to laryngeal spasm. Treatment with phenytoin sodium resulted in rapid improvement of the peripheral symptoms and simultaneous resolution of the laryngeal spasm.
