| Popis: | Objectives This study investigated the controversy of whether hypervascularity on color Doppler sonography correlates with thyroid malignancy by reviewing the literature and sonographic-pathologic correlation. Methods Over a 20-year period, 698 thyroid nodules had color Doppler and histopathologic data. Intranodular vascularity was graded 0 to 3+, and histopathologic findings were recorded. Results The data were collected from 698 patients (557 women and 141 men) with a mean age of 48 years (range, 16–87 years). Of the 698 neoplasms, 425 were malignant (mean size, 1.7 cm; range, 0.4–9 cm; 150 ≤1 cm), and 273 were benign. The carcinomas included 391 papillary, 12 Hurthle cell, 9 medullary, 6 follicular, 5 poorly differentiated, and 2 anaplastic. The grading of intranodular vascularity was 0 in 63.3%, 1+ in 12.9%, 2+ in 6.6%, and 3+ in 17.4%. Among thyroid carcinomas, follicular carcinoma and the encapsulated subtype of the follicular variant of papillary carcinoma had significantly higher intranodular vascularity than the rest (P |
