The mass compresses and drapes the normal parenchyma around it. Nodes may increase in diameter and be benign, although if the mass does not have a fatty hilum, biopsy may be necessary to confirm its etiology.
While all of the above modalities can potentially detect breast cancer, mammography is still the gold standard for early detection. Semin ultrasound CT MR. Schnitt SJ.
It's quite sensitive in identifying lesions that are suspicious for malignancy, but it is not very accurate in identifying which lesions are absolutely benign. THe BB indicates that it is palpable.
Role of sonography in evaluation of radial scars of the breast.
What to do with mixed signals? In this series, the patients ranged in age from 27 to 88 years and presented with a breast mass of a consistency similar to that of the adjacent tissue 18.
Individual and combined effects of age, breast density, and hormone replacement therapy use on the accuracy of screening mam mography. Since breast cancer arises from fibroglandular tissue, any mass that contains fat, or a mixture of fat and fibroglandular tissue, is benign and doesn't need biopsy. These include rheumatoid arthritis 26 , sarcoidosis 27 , psoriatic arthritis, and systemic lupus erythematosus 24.
The mammographic feature of greatest importance in assessing a relatively circumscribed isodense mass is its margination. Benign lesions tend to be isodense or less dense than the parenchyma and to have very circumscribed margins, whereas malignant masses are more often of greater density and have fine irregularity or micronodularity on their borders. Can MR imaging contribute in characterizing well-circumscribed breast carcinomas?
A microlobulated margin appears as fine nodularity or undulation of the edge of the lesion and implies a more malignant nature.
Idiopathic granulomatous mastitis: Case Rep Oncol.
A 49-year-old woman with a palpable left breast mass. Furthermore, when there is radiology-pathology discordance following image-guided biopsy, surgical excision is subsequently performed. Myofibroblastoma of the male breast: Steatocystoma multiplex.
Carcinomas tend to be of higher density, but these divisions are not absolute, and several benign lesions—including fibroadenomas, hematomas, and abscesses—may be of high density, depending on their size.
