We describe a rare case of non-immune hydrops fetalis caused by mediastinal teratoma. The sonographic appearance was that of a mixed cystic and solid mass in the antero-superior mediastinum. The teratoma, on post mortem, extended cranially to the upper part of the thyroid, exerting pressure and causing deviation of the trachea, oesophagus, and aortic arch. The pathogenesis of non-immune hydrops fetalis suggests obstruction of venous return caused by this tumour.
我们描述了一例由纵隔畸胎瘤引起的罕见的非免疫性胎儿水肿病例。超声表现为前上纵隔内的混合性囊实性肿块。尸检时，畸胎瘤向上延伸至甲状腺上部，对气管、食管和主动脉弓施加压力并导致其移位。非免疫性胎儿水肿的发病机制提示该肿瘤导致静脉回流受阻。
