摘　　要：目的:通过分析甲状腺结节发生囊性病变时的声像图特征及相应的病理学基础,探讨结节囊变在甲状腺良恶性间,良性与良性疾病间超声鉴别诊断要点。方法:对经手术和病理确诊的63例甲状腺恶性结节和229例良性结节超声声像图进行回顾性分析,分析内容包括边缘形态,内部回声及钙化,血流显像,周围组织情况等,并作统计学分析。结果:囊变结节中液性区所占比例,有无晕环,有无微钙化,血流显像,单发或多发,颈部有无异常淋巴结等在良恶性结节间,良性结节间均有显著性差异(P<0.01)。结论:甲状腺结节发生囊性病变时,由于其产生的病理基础不同,在良恶性间,良性与良性疾病间声像图存在差异,有助于三者的诊断与鉴别诊断。Objective： To evaluate the sonographic characteristics of thyroid nodule with cystic lesion, to reveal pathologic background, and to look for their characteristics of ultrasonographic differential diagnosis. Methods： 63 cases with malignant nodule and 229 cases with benign nodule confirmed by operation pathologic diagnosis were analyzed and reviewed. The contour margin, internal echo and calcification of nodule, surrounding tissues were observed. Results： There were significant differences（P〈0. 01） between benign nodule and malignant nodule in ratio of liquid focus to solid focus of cystic nodule,and faint rings around the foci,microcatcification, blood flow, single or plural loci, abnormal lymphy nodule. Conclusions：Because the pathologic basis of benign nodule and malignant nodule, benign nodule and malignant nodule are different, their ultrasonographic characteristics are different. This is helpful in differential diagnosis.
