A 34-year-old man was diagnosed with thymoma, which was evaluated preoperatively as stage II or III, with myasthenia gravis (MG).
The size of the tumor was 70 × 44 × 80 mm. No invasion to neighboring organs was observed.
Prednisolone was prescribed for stabilization of MG.
However, a myasthenic crisis (MC) occurred, and intensive care, including emergent endobronchial intubation followed by artificial ventilation, pulse steroid therapy, high-dose intravenous immunoglobulin, and tacrolimus hydrate, was initiated.
A chest computed tomography on day 6 revealed tumor reduction to 50 × 30 × 60 mm.
An extended total thymectomy by median sternotomy was performed, and artificial ventilation was continued after that.
Scheduled artificial ventilation and steroid therapy together can, therefore, enable complete resection of thymoma in patients undergoing treatment for MC.
While ventilation helps avert a respiratory failure, the steroid therapy temporarily reduces the tumor size, making resection easier.
