The purpose of this study was to determine the specific sonographic features of primary thyroid lymphoma and its color Doppler pattern compared to nodular goiter.
The sonographic findings for 13 surgically proven primary thyroid lymphomas were analyzed and compared to those for 27 nodular goiters.
In accordance with the suggested pathologic patterns, the sonographic patterns of primary thyroid lymphoma could be classified into diffuse and nodular or segmental types based on the distribution of hypoechoic and echogenic structures within the lesions. Some common sonographic characteristics suggesting thyroid malignancy could not facilitate differentiation of primary thyroid lymphoma from nodular goiter. However, a central blood flow pattern would favor the diagnosis of primary thyroid lymphoma, whereas a peripheral pattern would suggest the diagnosis of nodular goiter.
Primary thyroid lymphoma has characteristic sonographic and Doppler flow features. Along with several other parameters, a central blood flow pattern would highly suggest the diagnosis of primary thyroid lymphoma rather than nodular goiter.
本研究的目的是确定原发性甲状腺淋巴瘤的特定超声特征及其与结节性甲状腺肿相比的彩色多普勒模式。
分析了13例经手术证实的原发性甲状腺淋巴瘤的超声检查结果，并与27例结节性甲状腺肿的结果进行比较。
根据建议的病理模式，原发性甲状腺淋巴瘤的超声模式可根据病变内低回声和高回声结构的分布分为弥漫性、结节性或节段性类型。一些提示甲状腺恶性肿瘤的常见超声特征并不能有助于区分原发性甲状腺淋巴瘤和结节性甲状腺肿。然而，中央血流模式有利于原发性甲状腺淋巴瘤的诊断，而周边血流模式则提示结节性甲状腺肿的诊断。
原发性甲状腺淋巴瘤具有特征性的超声和多普勒血流特征。连同其他几个参数，中央血流模式高度提示原发性甲状腺淋巴瘤而非结节性甲状腺肿的诊断。
