A 3-1/2-year-old girl was diagnosed as having a mediastinal endodermal sinus tumor with pulmonary, bony, and hilar lymph node metastases. Following 7 months of treatment with chemotherapy, thoracic CT (computerized tomogram) scan showed the presence of a residual mass. Upon further surgical exploration the residual mass, which was found to be intrapericardial and arising from the ascending aorta, was resected. This second lesion was shown to be a benign cystic teratoma. The combination of an intrapericardial teratoma and a mediastinal endodermal sinus tumor in a female child is probably unique. The possible etiology for the combination of these two pathologies is discussed.
一名3岁半女童被诊断患有纵隔内胚层窦瘤，并伴有肺部、骨骼和肺门淋巴结转移。经过7个月的化疗后，胸部CT（计算机断层扫描）显示有残留肿块。进一步手术探查发现，残留肿块位于心包内，起源于升主动脉，遂予以切除。结果显示，这第二个病变是一个良性囊性畸胎瘤。女童心包内畸胎瘤与纵隔内胚层窦瘤并存的情况可能很罕见。本文讨论了这两种病理情况并存的可能病因。
