BI-RADS II

BI-RADS 2 is a benign category in breast imaging reporting and data system. A finding placed in this category should have a 100% chance of being benign.

Examples of such lesions or findings include:

• calcified fibroadenomas
• multiple secretory calcifications
• fat-containing lesions such as:
  • oil cysts
  • breast lipomas
  • galactoceles
  • mixed density hamartomas
• cutaneous neurofibromas : e.g. in neurofibromatosis type I (evidence of sarcomatous change is change is considered very low)
• intramammary lymph nodes
• breast sebaceous cysts
• simple breast cysts
• breast implants

Reporting recommendations

Although BI-RADS 1 and BI-RADS 2 both denote an essentially zero chance of malignancy, BI-RADS 1 is used in situations where the breast is completely unremarkable, and BI-RADS 2 is used when the radiologist wants to remark on a benign finding.

Any BI-RADS 2 breast finding is not expected to change over the follow-up interval. The radiologist should mention that it is a definite benign lesion.

Usual screening follow-up is recommended.
