Myasthenia Gravis VATS Thymectomy with Anterior Mediastinal Mass

A 35-year-old woman with a history of myasthenia gravis was recently assessed for worsening symptoms. She was found to have an anterior mediastinal mass consistent with a thymoma. She is booked for a VATS thymectomy due to difficult medical control of her symptoms and recent development of bulbar dysfunction as well as some clinical evidence of mass effect from the thymoma. You are assessing the patient in the Preadmission Clinic a week prior to her scheduled surgery. Medications: Pyridostigmine 180 mg qid Prednisolone 15 mg mane
