Role of ultrasound in the diagnosis of poorly differentiated thyroid carcinoma and anaplastic thyroid carcinoma / 肿瘤研究与临床

ABSTRACT

Objective To investigate the sonographic diagnostic value of poorly differentiated thyroid carcinoma and anaplastic thyroid carcinoma. Methods Ultrasonography of 22 cases with differentiated thyroid carcinoma and anaplastic thyroid carcinoma were observed with color doppler sonography.The shape,size,echo,boundary,microcalcifieation foci and blood stream distribution were studied,and contrasted with pathological diagnosis after operation.Lymphnode in cervical part and sulcus esophagus were examined.The characters of thyropathy according to the above sonographie features were judged. Results 16uhrasonography or before operation and biopsy,in which 9 were left,7 were right.6 cases were in both leaves.Ultrasound showed that 2 cases were poody differentiated thyroid carcinoma, 1 case was parathyroid carcinoma. 1 case was Hashimoto's thyroditis, and remainders were thyroid carcinoma. Conclusion Ultrasonography could enhance the detection rates and diagnose accordance rates of poorly differentiated thyroid carcinoma and anaplastic thyroid carcinoma.
