Incidental (18)F-FDG-avid breast lesions are commonly encountered in patients with cancer who undergo staging PET/CT. This pictorial essay discusses breast lesions that show increased FDG activity, mimicking breast cancer, with biopsy-confirmed benign diagnosis.
Acute and chronic inflammation, physiologic lactation, and benign breast masses, including silicone granuloma, fat necrosis, fibroadenoma, and postsurgical changes, may show increased FDG uptake on PET/CT. These conditions can often be differentiated from malignancy by correlative imaging, including mammography, sonography, or MRI.
在接受分期 PET/CT 的癌症患者中，常可发现偶然发现的（18）F-FDG 摄取增高的乳腺病变。本影像学文章讨论了经活检证实为良性的、表现为 FDG 摄取增高、类似乳腺癌的乳腺病变。
急性和慢性炎症、生理性哺乳期、良性乳腺肿块，包括硅酮肉芽肿、脂肪坏死、纤维腺瘤和手术后改变，在 PET/CT 上可表现为 FDG 摄取增高。这些病变通过包括乳腺 X 线摄影、超声或 MRI 在内的相关影像学检查，通常可与恶性肿瘤相鉴别。
