Objective: The aim of this study was to retrospectively analyze the ultrasonographic characteristics of medullary thyroid carcinomas (MTCs) with size less than 1 cm (MTMCs) compared with those of papillary thyroid microcarcinomas (PTMCs).
Materials and Methods: This study included 41 patients with 46 MTMCs between January 2008 to April 2017 and 104 consecutive patients with 136 PTMCs between January to June 2015. All thyroid carcinoma nodules were surgically and histologically proved. Age and nodules size were analyzed by independent sample t test. Sex, multiplicity and cervical lymph node metastases were evaluated by χ2 or Fisher’s exact tests. Univariate analysis and multivariate logistic regression analysis were performed on the sonographic features of thyroid carcinoma nodules, including location, composition, echogenicity, shape, margin, boundary, calcifications and vascularization degree.
Results: More MTMCs presented cervical lymph node metastases than PTMCs (36.59% vs 20.19%, p = 0.040). Compared with PTMCs, MTMCs tended to have an ovoid to round shape (P = 0.000, odds ratio [OR], 4.018; 95% CI, 1.295-12.473), more commonly showed solid composition (P = 0.004, OR, 0.13; 95% CI, 0.020-0.842), and macrocalcifications (P = 0.001, OR, 0.085; 95% CI, 0.016-0.454) and hypervascularity (P=0.000, OR, 10.778; 95% CI, 3.939-29.488). There were no significant differences in the location, margin, boundary, echogenicity, peripheral halo ring, the present of calcifications, microcalcifications and between MTMCs and PTMCs.
Conclusion: MTMCs have the ultrasonographic features of general malignant nodules, such as hypoechoic or markedly hypoechoic solid lesions with unique characteristics including ovoid to round shape, macrocalcifications and hypervascularity.
