Assuming stability perform a follow-up after one year and optionally another year. Spiculated with radiating lines from the mass is a very suspicious finding. Location and size should be applied in any lesion, that must undergo biopsy. Always try to avoid this category by calsificacion doing additional imaging or retrieving old films before reporting.

The arrangement of calcifications, the distribution, is at least as important as morphology. BI-RADS is a scheme for putting the findings from mammogram screening for breast cancer diagnosis into a small number of well-defined categories.

Here an example of global asymmetry.

In BI-RADS the use of percentages is discouraged, because in individual cases it is more important to take into account the chance that a mass can be obscured by fibroglandular tissue than the percentage of breast density as an indicator for breast cancer risk.

This is a benign finding. On the initial mammogram a marker is placed in the palpable tumor. This can cause worry and anxiety for everyone for those 6 months due to the uncertainty of the situation. Ultrasound can be helpful to define the margin better. If Mammography and US are performed: From Wikipedia, the free encyclopedia. In the paragraph on location we will discuss how we can be sure that the lymph node that we found with ultrasound is indeed the same as the mammographic mass.


Most biopsies today are done with a needle under local anesthetic and are painless.

Describe the breast composition. A resection was performed and only scar tissue was found in the specimen. The palpable cyst was painful, after informed consent uncomplicated puncture for suction of the cyst was performed.

The system is designed to standardize reporting, and is used by medical professionals to communicate a patient’s risk of developing breast cancer. Calcifications are now either typically benign or of suspicious morphology.

Asymmetries Findings that represent unilateral deposits of fibroglandulair tissue not conforming to the definition of a mass. Ultrasound examination was performed.

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. So add the following sentence in your report: Indication for examination Painful mobile lump, lateral in right breast.

They mampgrafia have characteristically benign appearances, and may be labeled with confidence.

When there is a significant finding use the descriptors in the table. It also facilitates outcome monitoring and quality assessment. Special cases Special cases are findings with features so typical that you do not need to describe them in detail, like for instance an intramammary lymph node birwds a wart on the skin. More references for this post are on this page.


This has to be differentiated from a mass. Use in findings for which any nonmalignant clasiticacion tissue diagnosis is automatically considered discordant Use in findings sufficiently suspicious to justify Category 5 and the patient or referring clinician refrain from biopsy because of contraindications or other concerns.

Bi-RADS for Mammography and Ultrasound 2013

DO Use for findings sufficiently suspicious to justify biopsy Use for findings sufficiently mamografis to justify biopsy and the patient or referring clinician refrain from biopsy because of contraindications. Mobile lump, lateral in left breast, since 2 months. Study the images and describe the calcifications. Casting microcalcifications appear linear, fragmented, and branching. So, further work-up may include spot compression, magnification, or breast ultrasound.

This implies a suspicious finding. It was discussed with the patient and the referring general practitioner, that in case of BI-RADS 4 a referral to the breast clinic is advised. Something benign like a cyst. Here images of a biopsy proven malignancy.
