We report the case of a patient, referred in our institution for a PET/CT for a suspected recurrence of papillary thyroid carcinoma. An intense cutaneous uptake of FDG was seen in the upper neck region. The clinical examination showed an indurate and thickened red descamative plaque evocative of psoriasis, and the patient reported a long history of psoriatic lesions of the skin, evolving for many years. This case illustrates an incidental finding which must be recognized, and not confounded with other causes of skin uptake. The FDG image is not surprising, as FDG uptake is expected in active inflammatory disease.
我们报告了一例患者，因疑似甲状腺乳头癌复发而在我院进行 PET/CT 检查。在颈部上区域可见 FDG 摄取明显增加。临床检查显示有坚硬、增厚的红色脱屑斑块，类似于银屑病，患者报告多年来皮肤有银屑病病变。这个病例说明了一个偶然的发现，必须加以识别，而不能与其他皮肤摄取原因混淆。FDG 图像并不奇怪，因为在活动性炎症性疾病中可以预期 FDG 摄取。
