A 42-year-old woman diagnosed with de-novo stage IV breast cancer underwent 18 F-fluoroestradiol (FES) PET/CT to evaluate the estrogen receptor status of metastatic lesions. The largest pulmonary nodule showed obvious FES uptake, consistent with pulmonary metastases from breast cancer. Interestingly, the images revealed a striking accumulation of FES in ground-glass attenuation in the left lobe of lung, suggestive of radiation pneumonitis.
一名42岁被诊断为新发IV期乳腺癌的女性接受了18F-氟雌二醇（FES）PET/CT检查，以评估转移病灶的雌激素受体状态。最大的肺结节显示有明显的FES摄取，符合乳腺癌肺转移。有趣的是，图像显示肺左叶磨玻璃影中有显著的FES聚集，提示放射性肺炎。
