甲状腺嗜酸性腺瘤的超声表现

目的：探讨甲状腺嗜酸性腺瘤超声声像图特点,提高超声诊断水平。方法：回顾分析15例经病理证实甲状腺嗜酸性腺瘤超声图像,其中女性13例,男性2例,年龄30～77岁（平均53.5岁）。结果：肿瘤均单发,大小10～50mm（平均26mm）。12个肿瘤呈实质性,3个呈囊实性。不均质低回声9个,均匀低回声2个,不均质中等回声2个,均匀中等回声2个。2个肿瘤内见细小钙化斑,1个伴声衰减。12个肿瘤边界清,3个边界欠清。14个肿瘤形态规则,1个形态不规则。4个肿瘤伴＂晕环征＂。6个肿瘤有膨胀感,9个肿瘤无明显膨胀感。13个肿瘤行彩色超声检查,9个内部见丰富分枝状血流,周边见环状血流,2个内部见短线状血流,周边环状,仅2个内部无彩色血流,周边见点状彩色血流。结论：甲状腺嗜酸性腺瘤主要表现为单发结节,实质为主,低回声为主,边界清,形态规则,肿瘤膨胀感不强,＂晕环征＂不多见,内部及周边有丰富彩色血流。甲状腺结节有上述表现者提示嗜酸性腺瘤的可能。必要时行术前结节细针穿刺抽吸细胞学检查,术中冷冻病理检查帮助诊断以确定手术方式。

Hurthle Cell Adenoma of the Thyroid: Sonographic Features

Objective:To investigate the sonographic features of Hurthle cell adenoma of thyroid.Methods:We retrospectively analyzed fifteen cases of pathologically proven HCA aged 30 to 77 years (mean age,53.5 years). Thirteen were female and two were male. Results: All HCA were single. The tumors ranged from 10 to 50mm in diameter (mean 26 mm). Twelve tumors were solid and three contained cystic components. Nine were inhomogeneously hypoechoic. Two were homogeneously hypoechoic. Two were inhomogeneously isoechoic. Tw...
