Abstract

Abstract: A 20-year-old man with papillary thyroid cancer received a fourth radioiodine regimen to treat 131 I-avid lung metastases. Posttherapeutic whole-body scan revealed focal radioiodine uptake on the anterior region of the left lower limb that was not visible on previous whole-body scan and which suggested skin contamination. Visual examination of the left leg evidenced a posttraumatic scab caused by a fall 2 weeks before. Skin metastasis was ruled out. 131 I SPECT/CT acquisition ruled out bony uptake and confirmed that the skin uptake was related to the superficial scab.

一名分化型甲状腺癌患者通过SPECT/CT显示的与创伤后疤痕有关的放射性碘摄取假阳性。

摘要：一名患有甲状腺乳头状癌的 20 岁男子接受了第四次放射性碘治疗，以治疗 131I 甲状腺素肺转移瘤。治疗后的全身扫描发现，左下肢前部有局灶性放射性碘摄取，而之前的全身扫描未发现这种情况，这表明皮肤受到了污染。对左腿的肉眼检查显示，这是 2 周前摔倒造成的创伤后结痂。排除了皮肤转移的可能。131I SPECT/CT 采集排除了骨骼摄取，并证实皮肤摄取与表皮结痂有关。
