INTRODUCTION
In the present study, we aimed to analyze ultrasonographic findings of metastases to the thyroid and explore the role of fine-needle aspiration cytology (FNAC) in the diagnosis of metastases to the thyroid.
METHODS
Twelve cases of cytologically or/and pathologically confirmed metastatic tumors of the thyroid gland were reviewed. All the primary thyroid lesions and lymphomas were excluded. The location, maximum size, echogenicity, shape, margin, presence of calcifications, vascularity, and cervical lymph nodes were assessed on ultrasonography. In addition, the results of cytology or pathology (or both) were noted retrospectively.
RESULTS
Eight of 10 patients were diagnosed correctly with FNAC. Two cases presented with diffuse involvement in both thyroid lobes. Nine cases demonstrated a hypoechoic nodule with an irregular margin, four of which had microcalcifications. One case presented with a mixed solid and cystic mass with an oval shape. The lesions with cervical lymph nodes were found in seven cases.
CONCLUSION
Most metastatic thyroid cancer has similar ultrasound features to primary thyroid cancer. In some cases with atypical US features, ultrasound diagnosis should be combined with the medical history. FNAC might be helpful in the diagnosis.
引言
在本研究中，我们旨在分析甲状腺转移瘤的超声表现，并探讨细针穿刺细胞学检查（FNAC）在甲状腺转移瘤诊断中的作用。
方法
回顾了12例经细胞学或/和病理证实的甲状腺转移瘤病例。排除所有原发性甲状腺病变和淋巴瘤。通过超声评估病变的位置、最大径、回声、形态、边界、钙化情况、血流情况及颈部淋巴结。此外，回顾性记录细胞学或病理学（或两者）结果。
结果
10例患者中有8例通过FNAC诊断正确。2例表现为双侧甲状腺叶弥漫性受累。9例表现为边界不规则的低回声结节，其中4例有微钙化。1例表现为椭圆形的实性和囊性混合肿块。7例发现有颈部淋巴结受累的病变。
结论
大多数甲状腺转移癌具有与原发性甲状腺癌相似的超声特征。在一些具有非典型超声特征的病例中，超声诊断应结合病史。FNAC可能有助于诊断。
