目的分析甲状腺腺脂肪瘤的超声征象,对误诊病例进行讨论以提高对该病的认识。方法收集7例我院经病理证实的腺脂肪瘤,分析其超声表现及误诊原因。结果 7例腺脂肪瘤均为单发结节,超声表现为椭圆形,A/T<1,边界清楚,直径为1.0~2.5cm,无液化现象,其中5个结节为高回声,5个结节血流信号为Ⅱ~Ⅲ级,1个结节出现点状钙化。结论腺脂肪瘤的声像改变取决于脂肪组织与腺瘤组织的分布情况,超声征象无特异度,具备恶性征象时可行细针穿刺活检以明确诊断。
Objective To analyze the ultrasound signs of thyroid gland lipoma and to discuss the misdiagnosis cases to improve the understanding of the disease. Methods Seven cases of pathologically confirmed adenoma of the lipoma in our hospital were collected and analyzed for their sonographic findings and causes of misdiagnosis. Results Seven cases of gland lipoma were single nodules. The ultrasound showed oval, A / T <1, clear boundary, diameter of 1.0 ~ 2.5cm, no liquefaction, of which 5 nodules were hyperechoic and 5 Nodules blood flow signal is Ⅱ ~ Ⅲ grade, a nodular punctate calcification. Conclusion The change of acromegaly of lipoma depends on the distribution of adipose tissue and adenoma. The ultrasonic sign has no specificity. When malignant signs are available, fine needle aspiration biopsy can be used to confirm the diagnosis.
