Abstract

Myasthenia gravis (MG) is the most common neuromuscular disease in dogs and cats. Its clinical manifestations vary depending on their classification, and can be classified as focal or generalized, and congenital or acquired. It commonly results in megaesophagus and aspiration pneumonia, and it is very important that both diseases are identified and treated. The gold standard for the diagnosis of MG in dogs and cats is the measurement of autoantibody concentration against nicotinic acetylcholine receptors (AChR) by radioimmunoassay. However, another method is the administration of acetylcholinesterase inhibitors for this diagnosis, in which an explicit improvement of muscle weakness is expected. Treatment is based on the use of acetylcholinesterase inhibitors, such as Pyridostigmine Bromide and Neostigmine, immunosuppressants, and supportive care. With this study, the aim was to report the case of an elderly dog, Golden Retriever breed, diagnosed with an acquired Myasthenia gravis that evolved from focal to generalized, and developed secondarily into megaesophagus and aspiration pneumonia.
