High resolution ultrasonography features have also been described as having a useful supporting role in the diagnosis of subacute granulomatous thyroiditis (ST), and images are generally characterized by heterogeneous hypoechoic areas of the affected tissue with lack of flow on color Doppler US.
To determine the sonographic features of subacute granulomatous thyroiditis.
We reviewed the medical records of patients referred at the Endocrine and Metabolic Unit of our Institution between January 2010 and December 2011.
A total of 7520 patients were evaluated in our department between January 2010 and December 2011. Among them, 22 (0.3%) patients had a diagnosis of ST (19 women and 3 men, 45.4 ± 9.7 year; range, 33-62 years). Ultrasound examination showed bilateral ST in 64% of patients. Thyroid volume was 13.2 ± 7.7 mL, without difference if ST was unilateral (13.2 ± 7.1 mL) or bilateral (13.9 ± 8.3 mL). On grayscale US, heterogeneous diffusely or focally marked hypoechoic areas, like "lava flow", were found in all the lesions.
Our data confirm the high sensitivity of US in the diagnosis of ST: diffuse hypoechoic and confluent areas with the characteristic features like "lava flow".
高分辨率超声特征在亚急性肉芽肿性甲状腺炎（ST）的诊断中也被描述为具有有用的辅助作用，图像通常表现为受影响组织的不均匀低回声区，彩色多普勒超声显示无血流信号。
确定亚急性肉芽肿性甲状腺炎的超声特征。
我们回顾了2010年1月至2011年12月在我院内分泌和代谢科就诊患者的病历。
2010年1月至2011年12月期间，我院共评估了7520例患者。其中，22例（0.3%）患者被诊断为ST（19例女性和3例男性，年龄45.4±9.7岁；范围33 - 62岁）。超声检查显示64%的患者为双侧ST。甲状腺体积为13.2±7.7 mL，单侧ST（13.2±7.1 mL）或双侧ST（13.9±8.3 mL）时无差异。在灰阶超声上，所有病变均发现不均匀的弥漫性或局灶性显著低回声区，类似“熔岩流”。
我们的数据证实了超声在ST诊断中的高敏感性：弥漫性低回声和融合区具有类似“熔岩流”的特征。
