[An experience of surgery for thymolipoma in a patient with amyotrophic lateral sclerosis].
A 48-year-old male with amyotrophic lateral sclerosis (ALS) was revealed to have an anterior mediastinal tumor, occupying left hemithorax on a chest CT. The tumor compressed the left lower lobe, resulting in a hypoventilation, which required a continuous ventilatory support. Although ALS has poor prognosis in general, we decided to remove the tumor surgically. Because the symptoms related to ALS was limited to his extremities, indicating he could potentially reestablish his life under ventilator-free condition, when a remove of the tumor improved a hypoventilation. A remove of the tumor was performed via antero-axillar thoracotomy, and reexpansion of the left lower lobe was achieved, followed by improvement of lung function and of respiratory symptoms. Histological examination revealed that the tumor was composed of mature adipose tissue and thymic tissue, diagnosed as thymolipoma. Postoperative course was uneventful.
