Ultrasonographic and pathological analysis of ineffective diagnosis of fine needle aspiration of thyroid nodules

Objective To analyze the ultrasonic images of thyroid nodules non-diagnosed by fine needle aspiration(FNA)so as to provide help for selecting cases and improving the diagnosis rate in clinical work.Methods The ultrasonic images of 97 nodules non-diagnosed by FNA confirmed by operation were analyzed retrospectively.To record the size,appearance,depth to skin,calcification and adjacent structure of thyroid nodules,and to analyze the pathological results.Results The ultrasonic signs of non-diagnosis thyroid nodules were as follows:the Nodules are located on the dorsal side or adjacent to important structures,such as trachea,esophagus and carotid artery,accounting for 25.8%(25/97);the nodules were in the right position but small,and the internal macrocalcifications almost covers the nodules,accounting for 15.5%(15/97);nodules of moderate size,peripheral annular calcification,accounting for 4.1%(4/97);The nodules are large and mainly cystic,accounting for 10.3%(10/97);Under the background of lymphocytic thyroiditis,the boundary of the nodule is not clear,accounting for 8.2%(8/97).All the 97 nodules,38 were malignant and 59 were benign,with malignant rate of 39.2%.Conclusion The evaluation of ultrasonic signs before FNA of thyroid nodules is helpful for operators to choose better clinical treatment plan and continuously improve the diagnostic rate of FNA.
