Abstract:
Objective To study the ultrasonographic features of benign thyroid nodules that were misdiag -nosed as malignant nodules .Methods The thyroid ultrasonic examination results of 31 822 healthy people who visited the Department of Health Management , Peking Union Medical College Hospital from January 2011 to De-cember 2014 were analyzed .Fine needle aspiration or surgical resection were performed in those highly suspected as malignant nodules according to some specific ultrasonographic features .Results A total of 162 nodules were suspected malignant in ultrasonography , among which 33 ( 20.37%) were benign based on pathologic results , primarily nodular goiter with calcinosis/fibrosis (12, 36.36%).Microcalcification (20), irregular boundary of the nodules (9), a taller-than-wide shape (6), and abundant and abnormal blood flow (6) were the most common ultrasonographic signs in turn in those misdiagnosed nodules .Conclusions Ultrasonography is the diag-nostic technique of choice for thyroid nodules .Accurate interpretation of the ultrasonographic features of thyroid nodules can improve the accuracy of diagnosis and facilitate the decision in surgery .
