Abstract:
Objective To determine the diagnostic value of plain CT in tuberous goiter and thyroid papillary carcinoma.Methods The CT images including 63 lesions from 58 patients with thyroid papillary carcinoma and 103 lesions from 86 patients with tuberous goiter proven by pathology were reviewed retrospectively.The analyses were mainly focus on the internal density,the presence of calcification, andthe relation of the lesion with the normal thyroid and adjacent tissue.Results There were statistically significant differences in the internal density,the morphology of calcification and the relation of the lesion with normal thyroid and adjacent tissue between the papillary carcinoma and tuberous goiter lesions.The common CT appearances of papillary carcinoma included uniform density,crab pattern change,micro calcifications and unclear boundaries of the lesion.Focal necrosis and cystic changes were also occasionally found in papillary carcinoma and usually occured at the peripheral area.Tuberous goiters usually manifested as mixed density with macro or eggshell calcifications as well as clear boundaries both with normal thyroid tissue and adjacent tissue.Conclusion The plain CT helps for the preliminary distinction of tuberous goiter and thyroid papillary carcinoma.
