A 54-year-old woman was referred for imaging studies after presentation for palpitations and a palpable thyroid nodule. The patient underwent a dual-phase single-agent Tc-99m sestamibi scan followed later by a thyroid ultrasound at an outside hospital. The Tc-99m sestamibi scan showed a marked focus of activity separate from the thyroid bed in the inferior left neck. Thyroid ultrasound showed a dominant calcified nodule in the left lobe of the thyroid, measuring 1.3 cm, as well as 3-mm cystic lesions in both lobes of the thyroid. Also, an iodine-123 scan was performed showing a cold nodule in the left inferior thyroid. During surgery, the patient underwent a left thyroid lobectomy for an intrathyroidal parathyroid adenoma.
一名54岁女性因心悸和可触及的甲状腺结节前来就诊，之后接受了影像学检查。患者在外部医院先进行了双期单剂锝-99m甲氧基异丁基异腈扫描，随后进行了甲状腺超声检查。锝-99m甲氧基异丁基异腈扫描显示左颈部下方有一个明显的放射性浓聚灶，与甲状腺床分离。甲状腺超声显示甲状腺左叶有一个占主导地位的钙化结节，大小为1.3厘米，甲状腺两叶还有3毫米的囊性病变。此外，还进行了碘-123扫描，显示甲状腺左下方有一个冷结节。手术期间，患者因甲状腺内甲状旁腺腺瘤接受了左侧甲状腺叶切除术。
