F-labeled fluoro-2-positron deoxyglucose emission tomography/computed tomography has been widely used in malignancy assessment, however, is not tumor-specific and may be taken up by non-malignant conditions such as sarcoidosis. Sarcoidosis is a systemic inflammatory disorder and scar sarcoidosis is a rare manifestation of the disease. A 60-year-old man with a past medical history of synchronous colon adenocarcinoma and clear cell renal cell carcinoma with clinical suspicion of tumor recurrence. F-labeled fluoro-2-positron deoxyglucose emission tomography/computed tomography scan demonstrated lesions with increased fluorodeoxyglucose uptake in mediastinal and left supraclavicular lymph nodes, along with hypermetabolic cutaneous foci that corresponded with previous surgical scars. Skin biopsy was suggestive of sarcoidosis.
F 标记的氟代 2 - 正电子脱氧葡萄糖发射断层扫描/计算机断层扫描已广泛用于恶性肿瘤评估，然而，它并非肿瘤特异性的，可能会被结节病等非恶性疾病摄取。结节病是一种全身性炎症性疾病，瘢痕结节病是该疾病的一种罕见表现。一名 60 岁男性，既往有同步性结肠腺癌和透明细胞肾细胞癌病史，临床怀疑肿瘤复发。F 标记的氟代 2 - 正电子脱氧葡萄糖发射断层扫描/计算机断层扫描显示纵隔和左锁骨上淋巴结有氟脱氧葡萄糖摄取增加的病变，以及与既往手术瘢痕相对应的高代谢皮肤病灶。皮肤活检提示为结节病。
