2. 성상으로는 K-TIRADS 4 입니다.
3. 악성 가능성은 10~40% 이며
4. 사이즈가 1cm이 넘으면 조직검사가 필요합니다.
5. 주기적인 검사를 통해 변화 양상을 잘 체크해 보세요
US pattern and malignancy risk of thyroid nodules and
biopsy size thresholds in the 2021 K-TIRADS
5. High suspicion (K-TIRADS 5)
-Solid hypoechoic nodule with any of the three suspicious US features
(punctate echogenic foci, nonparallel orientation, and irregular margins)
-Suspected malignancy risk (%) > 60
-Nodule size threshold for biopsy > 1.0 cm
4. Intermediate suspicion (K-TIRADS 4)
1) Solid hypoechoic nodules without any of the three suspicious US features or
2) Partially cystic or iso-/hyperechoic nodule with any of the three suspicious US features
3) Entirely calcified nodules
-Suspected malignancy risk (%) 10-40
-Nodule size threshold for biopsy > 1.0-1.5 cm
3. Low suspicion (K-TIRADS 3)
-Partially cystic or iso-/hyperechoic nodule without any of the three suspicious US features
-Suspected malignancy risk (%) 3-10
-Nodule size threshold for biopsy > 2.0 cm
2. Benign (K-TIRADS 2)
1) Iso-/hyperechoic spongiform
2) Partially cystic nodule with intracystic echogenic foci and comet-tail artifact
3) Pure cyst
-Suspected malignancy risk (%) < 3
-Nodule size threshold for biopsy Not indicated
