BI-RADS category 3

BI-RADS 3. Non-palpable sharply defined lesion with a cluster of punctate calcifications.

BI-RADS 3Probably Benign Finding - Initial Short-Interval Follow-Up Suggested:
A finding placed in this category should have less than a 2% risk of malignancy.
It is not expected to change over the follow-up interval, but the radiologist would prefer to establish its stability.Lesions appropriately placed in this category include:
-Nonpalpable, circumscribed mass on a baseline mammogram (unless it can be shown to be a cyst, an intramammary lymph node, or another benign finding),
- Focal asymmetry which becomes less dense on spot compression view
-Cluster of punctate calcifications
The initial short-term follow-up is a unilateral mammogram at 6 months, then a bilateral follow-up examination at 12 months and 24 months after the initial examination.
If the findings shows no change in the follow up the final assessment is changed to BI-RADS 2 (benign) and no futher follow up is needed.

BI-RADS 2
Benign Finding:Like BI-RADS 1, this is a normal assessment, but here, the interpreter chooses to describe a benign finding in the mammography report. Involuting, calcified fibroadenomas, multiple secretory calcifications, fat-containing lesions such as oil cysts, lipomas, galactoceles and mixed-density hamartomas all have characteristically benign appearances, and may be labeled with confidence.
The interpreter may also choose to describe intramammary lymph nodes, vascular calcifications, implants or architectural distortion clearly related to prior surgery, while still concluding that there is no mammographic evidence of malignancy.

BI-RADS 1
Negative:There is nothing to comment on.
The breasts are symmetric and no masses, architectural distortion or suspicious calcifications are present.

BI-RADS category 0

BI-RADS 0 at screening.
Additional ultrasound after referral was performed allowing final assessment.

Need Additional Imaging Evaluation and/or Prior Mammograms For Comparison

mammographic breast composition

Mammographic Breast Composition
Mammographic breast composition is described as follows:
1. the breast is almost entirely fat (<25% glandular)
2. scattered fibroglandular densities (25-50%)
3. heterogeneously dense breast tissue (51-75%)
4. extremely dense (> 75% glandular)

Linguini Sign

There are high signal subglandular implants with central serpentine, low signal line.

Normal breast on MRI demonstrates high signal fat intensity interspersed with low signal fibrous tissue. The implant material is of higher signal than normal breast fatty tissue. The lines, termed “linguini sign,” within the implant capsule indicate intracapsular collapse.

- Both breasts show many densely radiopaque nodules, compatible with free silicone residue from previously ruptured silicone implants.
-The newer left saline implant has ruptured and collapsed completely. The rounded density is the inflation port.
-The right saline implant is intact.

Discussion
Complications of breast implants include fibrous capsule formation (usual), capsule contracture, capsule herniation, intracapsular rupture, extracapsular rupture.
