Distribution of calcifications The arrangement of calcifications, the distribution, is at least as important as morphology.

Notice the distortion of the normal breast architecture on oblique view yellow circle and magnification view. Read more on breast calcifications.

The palpable mass is a simple cyst. Obscured or partially obscured, when the margin is hidden by superimposed fibroglandular tissue. Category 2 is a definitive benign finding and a routine screening.

The use of the term “density” is confusing, as the term “density” should only be used to describe the x-ray attenuation of a mass compared to an equal volume of fibroglandular tissue. Actually, radiologists were using 4 categories of mammogram density coding before bi rads existed.

Use in the presence of suspicious unilateral lymphadenopathy without abnormalities in the breast Do use Category 4a in findings as: Ultrasound examination was performed. After chemotherapy the tumor is not visible on the mammogram.

This will re-assure the good radiologists to keep doing whatever they are doing, but for radiologists whose accuracy statistics are not very good, it lets them know that they ought to get more training. In this patient this is not a normal variant, since there are associated features, that indicate the possibility of malignancy like skin thickening, thickened septa and subtle nipple retraction.

Global asymmetry consisting of an asymmetry over at least one quarter of the breast and is usually a normal variant. Coarse heterogeneous BI-RADS 4B Irregular, conspicuous calcifications that are generally between 0,5 mm and 1 mm and tend to coalesce but are smaller than dystrophic calcifications.

Sometimes repeated mammographic imaging with markers on the lesion found with US can be helpful. Associated features play a role in the final assessment. American College of Radiology. They all have characteristically benign appearances, and may be labeled with confidence. The document focuses on patient reports used by medical professionals, not “lay reports” that are provided to patients. Compare to previous studies. So, if you do come across these terms in your report it may be useful to know what they mean.

Concordant with the lump and the mass on the mammogram there is an oval simple cyst, parallel orientation, circumscribed, Anechoic with posterior enhancement. In the version the approach has changed.

Something benign like a cyst. These descriptors are arranged according to the risk of malignancy: It is not expected to change over the follow-up interval, but the radiologist would prefer to establish its stability. In the BI-RADS edition the assignment of the breast composition is changed into a, b, c and d-categories followed by a description: All types of asymmmetry have different border contours than true masses and also lack the conspicuity of masses.

For instance when we describe the shape or margin of a mass. Verbal discussions between radiologist, patient and referring clinician should be documented in the original report or in an addendum. This could be for instance ectopic glandular tissue within a heterogeneously dense breast. Here a hyperdense mass with an irregular shape and a spiculated margin.

By subdividing Category 4 into 4A, 4B and 4Cit is encouraged that relevant probabilities for malignancy be indicated within this category so the patient and her physician can make an informed decision on the ultimate course of action.

It was discussed biraxs the patient and the referring general practitioner, that in case of BI-RADS 4 a referral to the breast clinic is advised. This patient presented with a mass on the mammogram at screening, which was assigned as Briads 0 needs additional imaging evaluation.

The patient and the referring general practitioner clasificadion to await the results of the biopsy. Don’t recommend MRI to further evaluate a benign finding.

Integrate mammography and US-findings in a single report. Then use category 2 and add sentence stating the absence of mammographic correlate for the pathology.

Local compression views and ultrasound did not show any mass. This category is reserved for findings that do not have the classic appearance of malignancy but are sufficiently suspicious to justify a recommendation for biopsy.

The pathologist could report to you that it is sclerosing adenosis or ductal carcinoma in situ. Only years later, someone said, lets include these 4 breast density definitions into birads. Nevertheless the patient and the clinician preferred removal, because the radiologist was not able to present a clear differential diagnosis.
