Respiratory failure as the initial presentation of myasthenia gravis.

A number of reports describe the otolaryngologic manifestations of myasthenia gravis. Symptoms such as dysphagia, dysarthria, and dysphonia are quite common to myasthenia gravis, yet the usual onset of this disorder is insidious in nature. We report a case of an 18-year-old woman, previously undiagnosed, who presented with acute dysphagia followed by the rapid onset of respiratory failure. The diagnosis and treatment of myasthenia gravis are discussed.
