【摘要】：目的探讨超声对伴周边环形钙化良恶性甲状腺结节的鉴别诊断价值。方法回顾分析经手术病理确诊的73例伴周边环形钙化甲状腺结节的超声声像图特征,分析良恶性甲状腺结节的声像图特点,并进行统计学分析。计算各声像图特征对伴周边环形钙化良恶性甲状腺结节的鉴别诊断效能。结果 73例患者中,良性甲状腺结节58例(58/73,79.45%),恶性甲状腺结节15例(15/73,20.55%)。良、恶性结节的平均最大径、边界和内部回声、钙化周围有无声晕差异均无统计学意义(P均0.05)。良恶性结节伴结节性甲状腺肿的构成比差异、钙化厚薄是否均匀和钙化的连续性差异有统计学意义(P均0.05)。以伴结节性甲状腺肿诊断良性甲状腺结节的敏感度、特异度、阳性预测值、阴性预测值分别为77.59%(45/58)、60.00%(9/15)、88.24%(45/51)、40.91%(9/22);钙化厚薄不均诊断恶性甲状腺结节的敏感度、特异度、阳性预测值、阴性预测值分别为53.33%(8/15)、87.93%(51/58)、53.33%(8/15)、87.93%(51/58)。钙化连续中断诊断恶性甲状腺结节的敏感度、特异度、阳性预测值、阴性预测值分别为73.33%(11/15)、68.97%(40/58)、37.93%(11/29)、90.91%(40/44)。结论超声对于伴环形钙化甲状腺结节良恶性判断有一定的价值,钙化厚薄不均、连续性中断对诊断恶性病变价值更高。
[Abstract]:Objective to investigate the value of ultrasonography in the differential diagnosis of benign and malignant thyroid nodules with circumferential circular calcification. Methods the ultrasonographic features of 73 cases of thyroid nodules with circumferential circular calcification confirmed by operation and pathology were retrospectively analyzed. The sonographic features of benign and malignant thyroid nodules were analyzed and statistically analyzed. The differential diagnosis of benign and malignant thyroid nodules with circumferential circular calcification was calculated. There were 58 cases of benign thyroid nodules and 15 cases of malignant thyroid nodules. The mean maximum diameter of benign and malignant nodules was 15%. There was no significant difference in the boundary and internal echo, there was no significant difference in silent halo around calcification (P < 0.05). The ratio of benign and malignant nodules with nodular goiter was different. There were significant differences in the thickness and thickness of calcification and the continuity of calcification (P < 0.05). The sensitivity, specificity and positive predictive value of benign thyroid nodules with nodular goiter were evaluated. The negative predictive value was 77.59 / 45 / 58 / 60.0010 / 9 / 15 / 88. 24 / 45 / 51 / 40.91a / 10 / 9 / 22; The sensitivity, specificity, positive predictive value and negative predictive value of calcification in the diagnosis of malignant thyroid nodules were 53.33 and 87.93 / 58, respectively. The sensitivity, specificity and positive predictive value of calcification in the diagnosis of malignant thyroid nodules were 53.33 / 87.93 and 51 / 58 respectively. The negative predictive value was 73.33 / 11 / 15 / 68.97 / 40 / 58 / 37.93 / 11 / 29, respectively. Conclusion Ultrasound has a certain value in the diagnosis of benign and malignant thyroid nodules with circular calcification. The thickness of calcification is uneven and the continuity interruption is more valuable in the diagnosis of malignant lesions.
