Myasthenia gravis in an adolescent patient presenting to the pediatric emergency department.

Myasthenia gravis is a rare, chronic, autoimmune disorder characterized by postsynaptic dysfunction at the neuromuscular junction. The disease affects more females than males. We describe the case of a 17-year-old female adolescent with recurrent episodes of dysarthria and dysphagia and a history of aspiration pneumonia. A bedside edrophonium (Tensilon) test in our emergency department confirmed the diagnosis of myasthenia gravis.
