Resumo

The purpose of this study was to evaluate our ultrasonographic classification of thyroid nodules, based on echo structure, echogenicity, calcification, margin and analysis of the surrounding parenchyma. From January 1998 to January 2002, 2,468 consecutive patients with thyroid nodules were referred for thyroid ultrasonography and ultrasound-guided fine needle aspiration biopsy (USFNAB) in our Thyroid Unit. Among 1,039 nodules classified as benign on ultrasound, 998 (96.1%) were also benign on cytology, 37 (3.6%) were suspicious and only 4 (0.4%) were malignant. On the other hand, among 153 nodules classified as suspicious on ultrasound, 20 (13.1%) were suspicious and 88 (57,5%) were malignant on cytology. Of the 71 nodules suspicious on ultrasound submitted to surgery, 67 (94.3%) were malignant and 56 (96.6%) of 58 nodules considered benign were benign on pathologic studies. In conclusion, we advocate USFNAB in nodules classified as indeterminate or suspicious. Nodules classified as benign may be followed up at periodic intervals. (AU)
