METHODS: In our case, we report unexpected fibrous mediastinitis found after robotic thymectomy in a patient with myasthenia gravis (MG). The preoperative imaging indicated no obvious lesion in the mediastinum and the patient denied histories of both histoplasmosis and tuberculosis. After the operation, both proliferation of fibrous tissue and ectopic germinal centres (GCs) could be found in the thymus.
CONCLUSIONS: This rare case might enrich our knowledge of the relationship between FM and autoimmune diseases.
方法:在我们的例子中,我们报道了一名重症肌无力(MG)患者在机器人胸腺切除术后发现的意外纤维性纵隔炎.术前影像学显示纵隔无明显病变,患者否认组织胞浆菌病和结核病史。手术后,在胸腺中可以发现纤维组织和异位生发中心(GC)的增殖。
结论:这一罕见病例可能丰富了我们对FM与自身免疫性疾病之间关系的认识。
