A 37-year-old man with papillary carcinoma in an ectopic thyroid is presented. Excisional biopsy revealed the cervical mass to be a metastasis from thyroid cancer. X-ray, ultrasonography, and computed tomography, however, failed to identify the primary tumor in the thyroid. Incidental TI-201 uptake was noted in the midline of the anterior neck, and a palpable nodule was discovered in this area. Fine needle aspiration cytology demonstrated Class V papillary adenocarcinoma, and subsequent surgery confirmed a papillary carcinoma in the ectopic thyroid. This case suggests the usefulness of TI-201 scintigraphy for the detection of ectopic thyroid malignancy.
本文报告了一名37岁患有异位甲状腺乳头状癌的男性患者。切除活检显示颈部肿块为甲状腺癌转移灶。然而，X线、超声及计算机断层扫描均未能发现甲状腺的原发肿瘤。偶然发现前颈部中线有铊-201摄取，且该区域可触及一个结节。细针穿刺细胞学检查显示为V级乳头状腺癌，随后的手术证实异位甲状腺存在乳头状癌。该病例提示铊-201闪烁扫描术在检测异位甲状腺恶性肿瘤方面的有效性。
