A 59-year-old man was referred to the nuclear medicine service for a thyroid scan, as his neck was thick and the thyroid was not palpable. In the past the patient had undergone head and neck irradiation for acne. A 123I-thyroid scan was interpreted as a "cold" nodule in the lower pole of the right lobe, but thyroid ultrasound showed no thyroid abnormality. Repeat ultrasound examination eventually showed a tortuous carotid artery behind the lower pole of the right lobe of the thyroid that corresponded to the "cold" defect.
一名59岁男性因颈部增粗且甲状腺触诊不清，被转诊至核医学科进行甲状腺扫描。该患者过去曾因痤疮接受过头颈部放射治疗。123I甲状腺扫描显示右叶下极有一个“冷”结节，但甲状腺超声未显示甲状腺异常。重复超声检查最终显示甲状腺右叶下极后方有一条迂曲的颈动脉，与“冷”缺损相对应。
