摘要:

［目的］ 探讨应用高频超声探查甲状腺结节内钙化灶的临床意义。 ［方法］ 对93例共121个伴有钙化灶的甲状腺结节的超声声像图进行分析，并与病理结果进行对照。 ［结果］ 按照钙化分型，伴微钙化结节40个，粗钙化结节72个，周边钙化结节5个，孤立性钙化结节4个。其中伴微钙化结节的恶性率为87.50%（35/40），伴粗钙化结节的恶性率为13.89%（10/72），微钙化及粗钙化结节的良恶性比率之间差异有显著性意义（P<0.05）。周边钙化及孤立性钙化结节均为良性。 ［结论］ 高频超声可以清晰地显示甲状腺结节内不同类型的钙化灶，对于结节性质的判定具有重要的临床意义。

Abstract:

［Objective］ To discuss the clinical value of calcifications in nodules of thyroid gland detected by high-frequency ultrasonogrphy. ［Methods］ The ultrasound images of 93 patients including 121 nodules with calcifications were analyzed and compared with pathological examinations. ［Results］ According to the calcification types, 40 nodules with microcalcification, 72 nodules with intranodular coarse calcification, 5 nodules with peripheral calcification and 4 nodules with solitary calcification were detected. Thirty-five nodules with microcalcification nodules (87.50%) and 10 nodules with intranodular coarse calcification (13.89%) were proved to be malignancy by pathological result. There was a significant difference between the nodules with microcalcification and those with intranodular coarse calcification in malignant and benign rates (P<0.05). The nodules with peripheral calcification and isolated calcification were proved to be benign. ［Conclusion］ The different calcifications in nodules of thyroid gland can be detected by high-frequency ultrasonography clearly and it has an important clinical value in judging nature of nodules of thyroid gland.
