갑상선결절의 고해상능 초음파검사 소견 = High-Resolution Ultrasonographic Findings in Thyroid Nudules

다국어 초록 (Multilingual Abstract)

Ultrasonography, it's excellent ability of differentiating cystic from solid lesion and depicting detailed architecture, proved itself useful in the diagnosis of thyroid pathologies. Advanced high resolution equipments made hdden small lesion detected and finer structure clearly seen. They seemed to throw light on the histological diagriosis of thyroid diseases, especially differentiation of benignancy and malignancy. Author reviewed pictures of high-resolution ultrasonography of thyroid disease (24 cases) and correlated them with proven pathological findings. The results were as follows: 1. Multiplicity of lesion favors benignancy (4 cases). 2. Well defined margin favors benignancy (14/17), while ill defined margin favors malignancy (3/4), and lesion of no margin favors thyroiditis (3/3). 3. Surrounding halo favors benignancy (7 cases). 4. Hypoechogenicity were found in most of malignancy and thyroiditis. Cystic components in solid nodule were common findings in benign and ma ignant lesions. Calcification was not found in malignancy.
