ABSTRACT

Objective To investigate the value of CT scans in differential diagnosis of thyroid neoplasm.Methods CT findings ofthyroid neoplasm in 29 cases including 8 cases thyroid adenoma,4 cases nodular goiter and 17 cases thyroid carcinoma identified by operation and pathology were analyzed retrospectively.Results The contour of thyroid adenoma was distinct,a completely enhanced ring in 5 cases and enhanced nodules in 3 cases were showed on contrast-enhanced scan.4 cases of nodular goiter showed homogenous cystic low density the lesions were localized and distinct in contour,the cystic wall could be seen.Thyroid carcinoma appeared unhomogenous density,the edges contour of lesion was not distinct and infiltration on adjacent tissue might be seen.Conclusion CT scan might play an important role in diagnosis and differential diagnosis of thyroid neoplasm.
