目的探讨甲状腺H(u|¨)rthle细胞肿瘤的超声特征。方法回顾27个甲状腺H(u|¨)rthle细胞肿瘤的超声表现,并与病理结果对照。结果 27个甲状腺H(u|¨)rthle细胞肿瘤均为边界清晰、纵横比<1的椭圆形结节。29.6%为不伴囊性变的低回声结节,48.1%和22.1%为中等或中低混合回声结节,44.4%伴不同程度囊性变,3.7%有微小钙化,所有结节周边均有规整低回声晕。彩色多普勒血流显像88.8%周边血流环绕,内部血流丰富,11.1%仅内部少量血流。经超声引导下粗针穿刺活检,所有结节均能诊为甲状腺H(u|¨)rthle细胞肿瘤,但无法明确肿瘤良恶性。肿瘤完整切除后,2个结节由于H(u|¨)rthle细胞侵犯肿瘤包膜诊为H(u|¨)rthle细胞癌,其中1个内见小钙化,与超声结果相符。结论甲状腺H(u|¨)rthle细胞肿瘤的超声表现具有甲状腺良性结节的一般特点,其性质仅能通过完整肿瘤切除行病理学检查确定。 Objective To investigate the ultrasonographic features of thyroid H (u | ¨) rthle cell tumors. Methods The ultrasound findings of 27 thyroid H (u | ¨) rthle cell tumors were reviewed and compared with the pathological results. Results Twenty - seven thyroid H (u | ¨) rthle cell tumors were oval nodules with clear boundary and aspect ratio <1. 29.6% were hypoechoic nodules without cystic degeneration, 48.1% and 22.1% were moderate or moderate mixed echogenic nodules, 44.4% were cystic degeneration with varying degrees, 3.7% had microcalcification, and all the nodules had peripheral Regulated hypoechoic halo. Color Doppler flow imaging around 88.8% of the surrounding blood flow, the internal blood flow is rich, 11.1% only a small amount of internal blood flow. Guided by ultrasound guided needle biopsy, all nodules were diagnosed as thyroid H (u | ¨) rthle cell tumors, but not clear tumor benign and malignant. After complete neoplasm resection, H (u | ¨) rthle cells encroach H (u | ¨) rthle cells into H (u | ¨) rthle cell tumors, two of them were diagnosed as H (u | ¨) rthle cell carcinoma. Conclusion The sonographic features of thyroid H (u | ¨) rthle cell tumors have the general characteristics of benign thyroid nodules, and their properties can only be confirmed by pathological examination of complete tumor resection.
