Abstract

The literature of serendipitous findings on whole-body FDG PET continues to grow. Whole-body FDG PET imaging of a 24-year-old man with treated synovial sarcoma of the right upper extremity showed an abnormal focus of activity over the right chest in addition to abnormal uptake in the lungs. On reexamination, he was found to have a hitherto unknown 2.5-cm mobile nodule in the right breast. Histopathology confirmed it to be metastasis from the synovial sarcoma. Extramammary malignancies metastasizing to the breast constitute approximately 2% of all breast tumors.

摘要

关于全身氟代脱氧葡萄糖正电子发射断层扫描（FDG PET）偶然发现的文献不断增加。一名24岁接受过治疗的右上肢体滑膜肉瘤男性患者的全身FDG PET成像显示，除肺部有异常摄取外，右胸部还有一个异常的活性灶。再次检查时，发现他右侧乳房有一个此前未知的2.5厘米可移动结节。组织病理学证实其为滑膜肉瘤转移灶。乳腺外恶性肿瘤转移至乳房约占所有乳腺肿瘤的2%。
