Echogenic breast lesions are uncommon, comprising only 0. There are rare malignancies that can present as echogenic masses however, and thorough sonographic assessment according to the ACR BI-RADS criteria must be performed to correctly categorize these lesions and avoid misdiagnosis. In this article, we will review the imaging features of common benign and malignant echogenic breast lesions on ultrasound Table 1emphasizing their correlation with clinical history, mammographic appearance, lesion location and ultrasound features to establish a correct differential diagnosis, determine the need for biopsy and assess the imaging-pathology concordance after biopsy.
Ultrasound is a useful diagnostic tool for breast cancer detection. Breast ultrasound is used to distinguish solid from cystic masses using sound waves. Is it a hypoechoic mass or is it a hyperechoic lesion?
What is it? Breast ultrasound uses high frequency sound waves that cannot be heard by humans. It involves no ionizing radiation.
Radiological findings of breast involvement in benign and malignant systemic diseases. Although the primary purpose of periodic mammograms in screening programs is to identify lesions suspected of being carcinomas, the findings are often related to systemic benign or malignant diseases, rather than breast cancer. Although the involvement of breast structures in systemic diseases is unusual, it can be included in the differential diagnosis of masses, skin changes, calcifications, asymmetry, and axillary lymphadenopathy.
It also facilitates outcome monitoring and quality assessment. It contains a lexicon for standardized terminology descriptors for mammography, breast US and MRI, as well as chapters on Report Organization and Guidance Chapters for use in daily practice. The table shows a summary of the mammography and ultrasound lexicon.
Benign and malignant characteristics of breast lesions at ultrasound allow the classification as either malignant, intermediate or benign based on work published by Stavros et al. In all cases of lesions other than those which are absolutely benign, real time review by the radiologist is mandatory. Review of the mammogram is essential when interpretation of an ultrasound is performed.
Irregular hypoechoic masses in the breast do not always indicate malignancies. Many benign breast diseases present with irregular hypoechoic masses that can mimic carcinoma on ultrasonography. Some of these diseases such as inflammation and trauma-related breast lesions could be suspected from a patient's symptoms and personal history.
The ultrasound signs of breast masses are explained by the histopathological data. Ultrasound masses are classified according to their shape and margin. Round or oval masses are benign when their margins are circumscribed fibroadenoma, intramammary lymph node ; on the other hand, with non-circumscribed margins microlobulated or irregularmasses that are round or oval may be cancers.
Non-cancerous and cancerous breast lumps can be very different from each other when it comes to how they feel during a breast exam and what they look like in imaging tests. However, a number of benign breast changes mimic breast cancerso it sometimes takes further testing to know for sure what's going on in your breast. How a breast mass feels can give a doctor a fairly good idea whether a lump is a breast cancer tumor or a benign mass.
This term is used to describe what is seen on an ultrasound scan. Ultrasound uses sound waves that are absorbed by or bounce off of tissues, organs, and muscles. The waves form the black and white image you see on an ultrasound screen. Ultrasound is a useful tool to see if any part of your body has changed from its baseline state.
