color Doppler ultrasound and elastography features and diagnostic value in solid papillary carcinoma (SPC) of the breast.
Methods:
The sonographic data of 18 cases with SPC of the breast proved by pathology were analyzed.
Results:
The lesions were presented as intraluminal (solitary or multiple) or solid mass. Seventeen lesions were hypoechoic or iosechoic
and one was complex solid and cystic. Microcalcifications were found in 10 lesions. Posterior transmission showed posterior enhancement in 7 lesions
posterior attenuation in 3 lesions and no changes in 8 lesions.
Hypervascular
isovascular and hypo-/avascular were found in 12
2
4 lesions respectively. Seven carcinomas in situ with or without focal microinvasion scored as 1-2 by elastography. Three carcinomas with invasion scored as 4. Four solitary intraductal masses were diagnosed as papilloma. Fourteen multiple intraductal masses or solitary solid masses were diagnosed as malignant tumor (11 cases) or papilloma (3 cases) by ultrasound.
Conclusion:
The sonographic appearances of SPC are various. Ultrasound is useful for predicting the malignancy of multiple intraductal or solitary solid masses of SPC. The combination of grayscale ultrasound and elastography is useful for predicting tumor invasion.
