Popis: Myasthenia gravis (MG) is an autoimmune disease that affects the postsynaptic membrane at the neuromuscular junction. In MG, antibodies bind to acetylcholine receptors inducing muscle weakness. The weakness typically increases with exercise and repetitive muscle use. Improvement of muscular weakness after rest and/or administration of anticholinesterase drugs (edrophonium) are characteristic of MG. We report a patient with unexplained dysphagia, dysphonia, and dysarthria, whose diagnosis was suggested by high-resolution esophageal motility and edrophonium infusion. We highlight the importance of dysphagia as presenting or dominant symptom in MG and review the esophageal motility findings in this rare, but treatable disorder.
