(18)F-Fluorodeoxy glucose (FDG) activity reflects tissue glucose metabolism; malignancies, metastases, and acute infections have relatively increased FDG activity reflecting increased glucose metabolism. Benign adrenal disease demonstrating mild FDG uptake can be worrisome for metastasis in patients with a history of malignancy. Our patient with breast and colon cancer developed gastrointestinal bleeding on heparin therapy, enlarged adrenals with heterogeneous attenuation consistent with hemorrhage and blood clots as seen on abdominal computed tomography scan, and as abnormal intense FDG activity in the bilateral adrenal glands on positron emission tomography scan.
（18）氟脱氧葡萄糖（FDG）活性反映组织葡萄糖代谢；恶性肿瘤、转移灶和急性感染的FDG活性相对增加，反映葡萄糖代谢增强。对于有恶性肿瘤病史的患者，表现为轻度FDG摄取的良性肾上腺疾病可能令人担心发生转移。我们这位患有乳腺癌和结肠癌的患者在接受肝素治疗时出现胃肠道出血，腹部计算机断层扫描显示肾上腺增大，密度不均匀，符合出血和血凝块表现，正电子发射断层扫描显示双侧肾上腺有异常强烈的FDG活性。
