目的:分析甲状腺微小乳头状癌(PTMC)的超声图像特点,探讨误诊原因,提高对癌结节的诊断水平。方法:回顾性分析63例PTMC患者的70个癌结节(其中2例有3个癌结节,3例有2个癌结节)的形态、边界、边缘、内部回声、钙化类型、后方衰减、肿块周边及内部血流信号、颈部淋巴结,并与术后病理结果对照。结果:63例中,伴结节性甲状腺肿30例,合并桥本氏甲状腺炎5例,合并甲状腺瘤6例,单发癌22例,超声图像误诊率为17.14%(12/70),正确率82.86%(58/70)。结论:超声影像学在诊断PTMC方面有一定的难度,综合运用各项超声图像特点能有效减少误诊。
Objective: To analyze the characteristics of ultrasonography of thyroid papillary carcinoma (PTMC), explore the causes of misdiagnosis and improve the diagnosis of cancer nodules. Methods: The morphological features, borderline, margins, internal echoes, calcifications and posterior attenuation of 70 cancerous nodules (2 of them had 3 cancerous nodules and 3 had 2 cancerous nodules) were retrospectively analyzed in 63 patients with PTMC. , Tumor peripheral and internal blood flow signals, cervical lymph nodes, and postoperative pathological results. Results: Thirty cases with nodular goiter in 30 cases, Hashimoto’s thyroiditis in 5 cases, thyroid adenoma in 6 cases, single tumor in 22 cases, misdiagnosis rate of ultrasound image was 17.14% (12/70), correct Rate 82.86% (58/70). Conclusion: Ultrasound imaging in the diagnosis of PTMC has a certain degree of difficulty, comprehensive use of the characteristics of ultrasound images can effectively reduce the misdiagnosis.
