目的回顾经手术病理证实的25例甲状腺癌的彩色多普勒超声表现及对误诊原因进行分析,提高超声对其诊断的准确性。方法应用彩色超声诊断仪对25例患者甲状腺进行二维及彩色多普勒超声检查,并与手术病理相对照。结果 25例患者表现为大小不一的占位性病变,多数边界不清,内部回声不均匀,可有砂粒样钙化,周边及内部可见血流信号,部分病例可见颈部淋巴结转移。误诊为结节性甲状腺肿14例,甲状腺腺瘤出血囊性病变3例,甲状腺腺瘤8例。结论病灶过小、早期癌的恶性特征不明显以及甲状腺有多源性疾病存在,是造成误诊的主要原因,在检查过程中需注意鉴别诊断。
Objective To review the color Doppler echocardiography of 25 cases of thyroid carcinoma confirmed by surgery and pathology, analyze the causes of misdiagnosis and improve the diagnostic accuracy of ultrasound. Methods The color Doppler ultrasound was used to examine the thyroid in 25 patients with two-dimensional and color Doppler ultrasonography, and compared with the surgical pathology. Results Twenty-five patients presented with space-occupying lesions of different sizes. Most of the tumors had unclear boundary, uneven internal echo, grit-like calcification, peripheral and internal blood flow signals, and cervical lymph node metastases in some cases. Misdiagnosed as nodular goiter in 14 cases, thyroid adenoma hemorrhagic cystic lesions in 3 cases, thyroid adenoma in 8 cases. Conclusions The lesions are too small, the malignant features of early cancer are not obvious, and there are multiple thyroid gland diseases, which is the main reason of misdiagnosis. During the examination, differential diagnosis should be paid attention to.
