甲状腺嗜酸细胞肿瘤超声表现

Sonographic features of Hurthle cell neoplasm of the thyroid

目的 提高甲状腺嗜酸细胞肿瘤的超声图像认识.方法 回顾性分析病理确诊的10例（共13个病灶）甲状腺嗜酸性细胞肿瘤超声图像,总结其声像图特点.结果 肿瘤单发8例,多发2例.12个（92％）病灶位于右叶甲状腺.病灶大小0.6～5.2 cm,平均3.12 cm.实性9个（69％）,囊实性或囊性4个（31％）.良性11个（85％）,恶性2个（15％）.形态规整8个（62％）,边界清晰9个（69％）,周边可见声晕6个（46％）,表现为高低不等的不均匀混合回声9个（69％）,周边及内部血供丰富11个（85％）.边界不清及出现钙化者警惕恶性可能.结论 尽管上述超声特征对甲状腺嗜酸细胞肿瘤无特异性,但对有上述超声表现的甲状腺结节,应提示嗜酸细胞肿瘤可能.

Objective To describe the sonographic features of Hurthle cell neoplasm （HCN） of the thyroid.Methods This retrospective study included 10 cases （13 tumors） of pathologically proven HCN who underwent preoperative sonographic examinations,sonographic features were evaluated.Results Eight cases were single and 2 cases were multiple and 12 tumors（92%） were in the right lobe.The longest diameter of HCNs ranged from 0.6 to 5.2 cm（mean 3.12 cm）.Nine tumors（69%） were solid and 4 tumors（31%） contained cystic components.Eleven tumors （85%） were benign,2 tumors（15%） were malign.Eight tumors（62%） were regular,9 tumors（69%） had a clear margin and 6 tumors（46%）were with a integrity or percentage halo sign.The echogenicity of 9 tumors （69%） were hypoechoic,isoechoic,hyperechoic,or mixed.Plenty blood flow inside and/or around the tumor were detected in 11 tumors （85 %）.An unclear margin and coarse calcifications maybe predict a malign character.Conclusions Although many of the sonographic appearance we have observed were nonspecific,thyroid lesions with signs above perhaps raises the possibility of an HCN.
