71-year-old woman was pointed out to have an asymptomatic mediastinal tumor. Chest computed tomography(CT) showed a well-demarcated mass measuring 7 cm in diameter in the anterior mediastinum. We resected the mass through a median sternotomy. The tumor had a clear margin without invasion to the surrounding tissue and did not show continuity with the cervical thyroid gland. Histopathologically, the tumor was diagnosed as follicular thyroid carcinoma with capsular invasion. This is an exceptionally rare case.
一名71岁女性被指出患有无症状纵隔肿瘤。胸部计算机断层扫描（CT）显示前纵隔有一个边界清晰、直径7厘米的肿块。我们通过正中胸骨切开术切除了该肿块。肿瘤边缘清晰，未侵犯周围组织，与颈部甲状腺无连续性。组织病理学上，该肿瘤被诊断为伴有包膜侵犯的滤泡状甲状腺癌。这是一个极其罕见的病例。
