filter terms:

Many neuromuscular conditions cause bulbar and limb weakness, and when several conditions coexist they present additional diagnostic challenges. Here we describe a case of a 45-year-old woman with antibody positive myasthenia gravis since age 16, who then develops treatment-resistant weakness due to genetically proven oculopharyngeal muscular dystrophy. We conclude that the development of treatment-resistant weakness in myasthenia gravis should spur further work up for other neuromuscular disorders including oculopharyngeal muscular dystrophy.
