CT diagnosis and differentiation of thyroid tumors

Objective: To explore the value of CT scan on diagnosis of thyroid tumors.Methods: Thirty six cases of thyroid tumors proved by surgery or pathological data were analyzed,retrospectively.All of them were examined by plain CT scan,of 26 were additionally examined by enhance scan.Results: Among 36 cases,ten thyroid adenomas had a complete capsule and no metastatic lymph node.Among 26 thyroid carcinomas,22 were papillary carcinoma,3 were folliculla carcinoma,1 case was undifferentiated carcinoma,of 12 cases were found calcification,including fine granular calcifications and small calcification,20 cases had unclear margin and infiltrative growth,15 cases were revealed metastatic lymph node in the neck.Conclusion: The calcification in lesions,the relationship between the lesions and normal thyroid tissue or surrounding structures and cervical metastatic lymph nodes or metastasis is main point for CT diagnosis and differential diagnosis in thyroid tumors.CT scan might take an important value on diagnosis and differential diagnosis in thyroid tumors.
