Abstract:
Objective To study helical CT manifestations of neck lymph node metastasis in thyroid carcinoma.Methods Forty-four patients of neck lymph node metastasis in thyroid carcinoma were performed helical CT scans and were analyzed retrospectively to compare with pathology and operation.CT manifestations mainly included:density,sector and calcification.Results On the one hand,CT manifestations had common character of neck lymph node metastasis;that was low-attenuant center and rim enhancement,on the other hand,CT manifestations showed:(1)thinness-sand and mottle calcification in the metastatic lymph node;(2)metastatic lymph node obvious enhancement.After enhance average density ranged from 28.00~50.54 HU to 62.85~145.78 HU,average density was near or more than 100 HU.Conclusion In metastatic lymph node of thyroid carcinoma,the findings of thinness-sand and mottle calcification suggest malignant tumor in thyroid focal,and metastatic lymph nodes were obviously enhanced;average density of lymph node after enhancement is near or more than 100 HU.
