目的:研究甲状腺良性肿瘤的B超观察效果。方法:选取本院于2010—2011年间收治的40例B超诊断为甲状腺腺瘤的患者,将其手术以及病例检查结果进行核对作进一步研究。结果:40例患者均为单发性结节,直径分布在1—5cm,平均长度为2.3cm。大体形态规整,与周围组织界限清晰。肿块直径在1—2cm之间者,周边部分均有完整的低回声晕。结论:单结节的结节性甲状腺肿即为甲状腺腺瘤。其镜下形态,主要表现为小滤泡型腺样结构,这与滤泡性甲状腺腺瘤的病理基础相近,因此其声像图以及退行性变化的声像图均相似。由此提示,边界的清晰与否、是否有低回声晕,不可作为甲状腺腺瘤与结节性甲状腺肿鉴别诊断的绝对标准。
Objective: To study the thyroid benign tumor B ultrasound observation. Methods: Forty cases of thyroid adenoma diagnosed by B ultrasound in our hospital from 2010 to 2011 were selected for further study. The results of surgery and case examination were checked for further study. RESULTS: All 40 patients had solitary nodules with a diameter of 1-5 cm and an average length of 2.3 cm. The general shape of regular, clear boundaries with the surrounding organization. Mass in the 1-2cm diameter between the peripheral parts have a complete hypoechoic halo. Conclusion: Single nodular goiter is thyroid adenoma. The microscopic morphology, mainly for the small follicular adenoid structure, which is similar to the pathological basis of follicular thyroid adenoma, so the sonography and degenerative changes in sonograms are similar. This suggests that the border is clear or not, whether there is hypoechoic halo, thyroid adenoma can not be used as the differential diagnosis of nodular goiter absolute standard.
