Lung adenocarcinoma with humeral metastasis as the initial presentation is rare. We reported FDG PET/CT findings of solitary humeral metastasis from adenocarcinoma of the lung in a 57-year-old man with the right upper arm pain as the initial presentation. MRI showed bone destruction of the right humerus with a soft tissue mass, suggesting the possibility of malignancy. FDG PET/CT showed that the right humeral mass had strong activity, and there were additional FDG lesions in the right armpit, left apical lung, and left adrenal gland, which was later confirmed as humeral metastasis from lung adenocarcinoma by pathological examination.
以肱骨转移为首发表现的肺腺癌较为罕见。我们报告了一例57岁男性，以右上臂疼痛为首发表现，FDG PET/CT显示为肺腺癌孤立性肱骨转移。MRI显示右肱骨骨质破坏并伴有软组织肿块，提示恶性可能性。FDG PET/CT显示右肱骨肿块有强烈活性，右腋窝、左肺尖和左肾上腺还有其他FDG病灶， later confirmed as humeral metastasis from lung adenocarcinoma by pathological examination这句话有误，正确的应该是“后经病理检查证实为肺腺癌肱骨转移” 。
