Thyroid calcifications: sonographic patterns and incidence of cancer.
We investigated the incidence of cancer in surgically resected 151 thyroid nodules in 101 patients according to their calcification patterns on preoperative ultrasonography (US). Calcification was detected in 57 (38%) nodules, 31 (54%) of which was histologically diagnosed as cancer. According to the calcification types, 9 of 11 nodules with microcalcifications, 15 of 29 nodules with intranodular coarse calcification, 6 of 14 nodules with peripheral calcification and 1 of 3 calcified spots without surrounding tumor were diagnosed as cancer.
