作者检查和治疗1198例全身型肌无力,其中106例(8.8%)查出胸腺肿瘤.男性49,女性57,性别差别不大.而胸腺增生伴肌无力病例女性偏多(4∶1).中年人较多见.手术和组织学检查证实诊断98例.据作者观察,胸腺瘤伴肌无力有下列特点:①、肌无力病史较短,5年以上只有8例.②、绝大多数病例疾病的发展是进行性的,很快出现骨骼肌系严重障碍,主要是延髓障碍,因此机体的重要功能(咀嚼、吞咽、呼吸)障碍.③、胸腺瘤病例的肌营养不足比胸腺增生病例多见.通常因肿瘤不大,病情严重,手术前诊断胸腺瘤困难.最简单而有效的诊断方法是纵膈充气造影术,特别是结合断层X线摄影.在断层照片上,肿瘤呈现圆形或多环形结构,边界清楚.而胸腺增生沿胸骨呈 The authors examined and treated 1198 cases of systemic muscle weakness, of which 106 cases (8.8%) detected thymic tumors. Males 49, females 57, gender differences are not. And thymic hyperplasia with myasthenia gravis cases are more female (4:1). Middle-aged people are more common. Surgical and histological examination confirmed the diagnosis of 98 cases. According to the authors observation, thymomas with muscle weakness have the following characteristics: 1, a short history of muscle weakness, more than 5 years, only 8 cases. 2, the vast majority The development of the disease in the disease is progressive, and soon there are serious skeletal muscle disorders, mainly medullar obstruction, so the body’s important functions (chewing, swallowing, breathing). 3, thymoma cases of muscular dystrophy than thymic hyperplasia More common. Usually due to small tumors, serious illness, difficult to diagnose thymoma before surgery. The most simple and effective diagnostic method is mediastinal pneumatic radiography, especially combined with tomography. In the photo of the tumor, the tumor is round Or multi-ring structure with clear boundaries and thymus hyperplasia along the sternum
