Ultrasound
Indications of breast ultrasonography [1][2]
- The first imagery modality in patients with palpable masses under 40 years old
- Adjuntive modality to mammography for patients older than 40 years
- Abnormal findings on mammography or MRI
- Breast implants problems
- Determination of mass with microcalcification and architectural distortion findings on mammography
- Screening method for high risk individuals for breast cancer who can not undergo breast MRI
- Evaluating axillary lymphadenopathy
Breast ultrasound improves breast cancer detection. According to the fact that 11% of palpable breast cancers were detected by ultrasound while these lesions were occult on mammography features. Combination of mammography and ultrasound increase cancer detection rate to 14% [3].
| Types of breast lumps | Characteristic findings |
|---|---|
| Cyst | Simple cyst: well-circumscribed, anechoic contents, thin echogenic external capsule, enhanced through-transmission, subtle acoustic shadowing at the ages

| Abscess | Hypo-anechoic mass with irregular margins and peripheral hypervascularity |
| Mastitis | Subcutaneous and parenchymal edema with small fluid collection and diffuse hypervascularity |
| Galactocele | Moderately echogenic contents with fat spreading heterogenously in the liquid component |
