A 35-year-old woman affected by a well-differentiated papillary thyroid carcinoma was referred to our hospital to perform a (131)Iodine ((131)I) whole body scintigraphy for restaging purpose. The patient had been previously treated with total thyroidectomy and three subsequent doses of (131)I for the ablation of a remnant jugular tissue and a suspected metastatic focus at the superior left hemi-thorax. In spite of the previous treatments with (131)I, planar and tomographic images showed the persistence of an area of increased uptake at the superior left hemi-thorax. This finding prompted the surgical resection of the lesion. Histological examination of the surgical specimen showed the presence of a pulmonary tissue consistent with pulmonary sequestration. Even though rare, pulmonary sequestration should be included in the potential causes of false-positive results of radioiodine scans.
一名患有高分化乳头状甲状腺癌的35岁女性被转诊至我院，以进行¹³¹碘（¹³¹I）全身闪烁扫描以重新分期。该患者此前已接受全甲状腺切除术，并随后三次服用¹³¹I以消融残留的颈静脉组织和左上半胸疑似转移灶。尽管此前已进行了¹³¹I治疗，但平面和断层图像显示左上半胸仍有摄取增加区域。这一发现促使对该病变进行手术切除。手术标本的组织学检查显示存在与肺隔离症相符的肺组织。尽管罕见，但肺隔离症应被纳入放射性碘扫描假阳性结果的潜在原因之中。
