| PURPOSE : To evaluate the usefulness of ultrasonography in the differentiation between benignity and malignancy in
the evaluation of small thyroid nodules (the longest diameter < 10 mm).
MATERIALS and METHODS : Fine needle aspiration or surgery was performed for the evaluation of seventy two (44 benign
and 28 malignant) small thyroid nodules from fifty eight patients. Ultrasonographic findings were retrospectively
reviewed for the margin, echogenecity, presence of microcalcification, intranodular cystic change
and peripheral hypoechoic halo.
RESULTS : Ill-defined margin was more common in malignant nodules (61% vs 11%, p<0.05). In internal echogenecity,
either iso- or hyperechogenicity was more coomon in benign nodules (45% vs 18%, p<0.05) while
malignant nodules were often markedly hypoechoic (39% vs 18%, p<0.05). Malignant nodules contained more
microcalcifications (36% vs 9%, p<0.05) whereas benign nodules often showed intranodular cystic
change(39% vs 7%, p<0.05) and hypoechoic halo (41% vs 18%, p<0.05).
CONCLUSION : Ultrasonography can be useful in the differentiation between benign and malignant small thyroid nodules. |
