【摘要】：目的探讨MSCT对于结节性桥本氏甲状腺炎(NHT)的诊断价值。方法回顾性分析和总结经手术病理或穿刺活检证实的40例(47个结节)NHT患者的MSCT表现,所有病例均行平扫和增强扫描。结果 19个结节发生在正常甲状腺实质背景,28个发生在弥漫性桥本氏甲状腺炎背景。35个为单发,12个为多发。47个结节均为实性,且45个密度均匀。在正常甲状腺实质背景下,17个为低密度,2个为等密度;在弥漫性桥本氏甲状腺炎背景下,15个为低密度,13个为等或稍高密度。43个呈类圆形,39个未超出甲状腺轮廓生长。平扫时,42个显示边界模糊,增强扫描43个显示边界模糊。40个纵横比1。44个结节未见微小钙化。增强扫描时,31个显示强化程度较周围甲状腺实质背景低,16个强化程度与周围甲状腺实质背景一致。14例颈部出现肿大淋巴结。结论甲状腺内等、低密度圆形实性结节,边界模糊、纵横比1、未超出甲状腺轮廓生长、无微小钙化,强化程度较周围甲状腺实质略低或一致,强化后结节边界仍模糊,上述特点有助于诊断NHT。
[Abstract]:Objective to investigate the diagnostic value of MSCT in nodular Hashimoto's thyroiditis.Methods the MSCT findings of 40 cases (47 nodules) confirmed by pathology or biopsy were retrospectively analyzed and analyzed. All patients underwent plain scan and enhanced scan.Results 19 nodules occurred in normal thyroid parenchymal background, 28 in diffuse Hashimoto's thyroiditis background, 35 were single, 12 were multiple. 47 nodules were solid and 45 had uniform density.In normal thyroid parenchymal background, 17 were low density, 2 were isodensity, 15 were low density and 13 were equal or slightly high density in diffuse Hashimoto's thyroiditis. 43 were round and 39 did not exceed the outline of thyroid gland.In plain scan, 42 cases showed blurry boundary, 43 contrast enhanced scans showed blurred boundary, and 40 aspect ratio 1.44 nodules showed no microcalcification.In contrast to the surrounding thyroid parenchyma, the enhancement degree in 31 cases was lower than that in the surrounding thyroid parenchyma background, and 16 enhancement degrees were consistent with the surrounding thyroid parenchyma background. 14 cases had enlarged lymph nodes in the neck.Conclusion in the thyroid gland, there is a low density circular solid nodule with a vague boundary, a aspect ratio of 1, no growth beyond the outline of the thyroid gland, no microcalcification, a slight or consistent enhancement degree than the surrounding thyroid parenchyma, and the boundary of the enhanced nodule is still blurred.These characteristics are helpful for the diagnosis of NHT.
