Patients with myasthenia gravis should consult the department of neurology, as myasthenia gravis is an immune-related neuromuscular junction disorder. Patients often exhibit pathological fatigue, skeletal muscle involvement, and unaffected smooth muscles. The most common type is ocular myasthenia, followed by mild and moderate generalized forms. Adult patients often have thymomas or thymic hyperplasia. Upon diagnosis of myasthenia gravis, it is essential to perform a comprehensive thymic CT scan. If thymic abnormalities are present, referral to thoracic surgery for treatment is needed. If there is no thymic disease, high-dose steroid pulse therapy may be considered. Additionally, it is crucial to determine whether the patient has other coexisting immune abnormalities, such as hyperthyroidism or connective tissue disease, and tailor the treatment accordingly.
