Steroid therapy without primary dose escalation for postthymectomy crisis in 2 thymomatous myasthenia gravis patients.

We report 2 cases of thymomatous myasthenia gravis associated with postoperative crisis and medicated with steroid therapy using prednisolone without primary dose escalation. Two women, a 38 years old and the other 64 years old, underwent extended thymectomy under the diagnosis of myasthenia gravis associated with invasive thymoma. Bulbar symptoms in both were severe despite preoperative anticholinesterase medication.
