目的:对经手术病理检查证实的甲状腺癌超声表现进行对比观察。方法:选择经术后病理检查证实的甲状腺癌24例,着重将术前二维及彩色多普勒超声检查结果(包括甲状腺肿块大小、形态、内部回声和血供情况,以及邻近转移淋巴结等)与术后病理检查结果进行对比观察。结果:术前超声检查发现低回声结节20例,内部伴有微小钙化17例,边界模糊不清17例,形态不规则15例;彩色血流分布Ⅲ级13例;周围组织浸润5例;同侧淋巴结转移4例。术后病理检查结果为甲状腺乳头状癌23例,髓样癌1例。结论:当超声检查发现甲状腺结节为低回声、边界模糊不清、形态不规则、内部血流信号丰富且有微小钙化时,应高度警惕恶性肿瘤可能。
Objective: To compare the ultrasound manifestations of thyroid carcinoma confirmed by surgery and pathology. Methods: Twenty-four cases of thyroid carcinoma confirmed by postoperative pathology were selected. The results of two-dimensional and color Doppler ultrasonography (including thyroid mass, morphology, internal echo and blood supply, and adjacent metastatic lymph nodes, etc.) And postoperative pathological examination results were compared. Results: Preoperative ultrasonography showed 20 cases of hypoechoic nodules with 17 cases of microcalcifications, 17 cases of blurred border, 15 cases of irregular shape, 13 cases of grade Ⅲ color flow distribution and 5 cases of infiltration of surrounding tissues. Ipsilateral lymph node metastasis in 4 cases. Pathological examination showed thyroid papillary carcinoma in 23 cases and medullary carcinoma in 1 case. CONCLUSIONS: When thyroid nodules are found to have hypoechoic echocardiographic findings, unclear boundaries, irregular shape, and abundant internal blood flow signals with microcalcifications, the possibility of malignancy should be highly observed.
