Ultrasound findings of benign and malignant breast lesions

Ultrasound findings of benign and malignant breast lesions

• Appearance

  • Homogeneous texture or echo-free space
  • Heterogeneous texture, Hypoechoic

• Structure

  • Fluctuant
  • Firm, rigid

• Margins

  • Well-circumscribed lesion with smooth margins
  • Irregular mass with poorly defined, spiculated margins

• Further findings

  • Posterior enhancement (cyst) or thin echogenic rim with pseudocapsules (fibroadenoma)
  • Posterior shadowing

• Further management

  • Regular check-ups Possibly surgical excision
  • Fine needle aspiration or core needle biopsy

• In postmenopausal women and women ≥ 30 years of age with a suspicious breast mass, mammography is preferred over ultrasound.

• In premenopausal women < 30 years of age, ultrasound is preferred, because the higher density of breast tissue decreases the diagnostic power of mammography.
