目的探讨彩色B超在亚急性甲状腺炎(SAT)临床诊疗中的作用。方法29例临床诊断SAT患者,诊疗过程中平均进行2·6(2~9)次彩色B超检查,以辅助诊断及调整用药。结果声像学表现为甲状腺肿大26例(双侧15例,单侧11例);29例均探及形态不规则、边缘欠清晰的不均匀低回声区(直径平均5·6±2·3mm,双侧、多发16例,单发13例);糖皮质激素或非甾体类抗炎药治疗过程中13例17次依照临床和血液学指标减量或停药,但彩色B超低回声区仍呈现甚至扩大;7例临床和血液学正常2个月、低回声声像区消失后停药,未再复发。结论彩色B超检测SAT敏感,有独特的方便性和可重复性,可为SAT临床诊疗提供有价值的信息。
Objective To investigate the role of color B ultrasound in the diagnosis and treatment of subacute thyroiditis (SAT). Methods Twenty - nine patients with SAT were diagnosed clinically. An average of 2.6 (2 ~ 9) color B - ultrasound examinations were performed during diagnosis and treatment to assist in the diagnosis and adjustment of medication. Results Twenty-six cases of thyroid enlargement (15 cases in both sides and 11 cases in unilateral sclerosis) were found in the sonography; 29 cases were found with non-uniform hypoechoic areas with unequal margins (diameter average 5.6 ± 2 · 3 mm, bilateral, multiple in 16 cases, single in 13 cases); glucocorticoid or non-steroidal anti-inflammatory drugs in the course of treatment of 13 cases of 17 according to clinical and hematological indicators of weight reduction or withdrawal, but ultra-low color B Echogenic zone is still showing or even expanding; seven cases of normal clinical and hematological 2 months, hypoechoic area disappeared after discontinuation, no recurrence. Conclusion The color B-mode detection of SAT is sensitive and has unique convenience and repeatability, which can provide valuable information for the clinical diagnosis and treatment of SAT.
