[edit] Discussion of Fibroadenoma

  • Fibroadenomas are benign fibroepithelial tumors that develop in the lobules at the ends of mammary gland ducts.
  • Composed of epithelium and stroma
  • Fibroadenomas are the breast tumors most commonly found in adolescent girls and young women.
  • When palpable, fibroadenomas are smooth, mobile and firm or rubbery.
  • Multiple in 15% of cases
  • Occasionally develop into very large masses and are then called juvenile giant fibroadenomas.

[edit] Imaging Findings for Fibroadenoma


[edit] Mammogram

  • At mammography, fibroadenomas appear as well-defined round, oval, or lobulated masses.
  • The masses may be calcified, with the most common pattern of calcification being initial small peripheral dots that coalesce over time into coarser popcorn-shaped features.

[edit] US

  • Fibroadenoma appears as a well-circumscribed elliptic mass that is either hypoechoic or isoechoic and has uniform echogenicity.
  • Typically larger in the transverse than in the anteroposterior direction.
