[edit] Discussion of Radial scar

  • Radial scars (complex sclerosing lesions) are not truly scars
  • Idiopathic entities unrelated to prior surgery or trauma.
  • Proposed possible causes include localized inflammatory reaction and chronic ischemia with subsequent slow infarction
  • Reported prevalence of radial scars is 0.1–2.0 per 1,000 screening mammograms
  • Major clinical significance pertains to an association with atypical ductal hyperplasia and carcinoma that is seen in up to 50% of cases.
  • Excisional biopsy should be performed when imaging findings are consistent with radial scar.
  • Core needle biopsy, fine-needle aspiration, and frozen sectioning are not routinely recommended for definitive diagnosis because the precise pathologic diagnosis of these lesions is difficult.

[edit] Imaging Findings for Radial scar

[edit] Mammogram

  • Manifests as an asymmetric density or architectural distortion with central translucent areas representing fat.
  • Long, thin radiating spicules against a background of radiolucent fat create a "black star" appearance.
  • Radial scars are typically planar in configuration and therefore may have varying appearances on orthogonal views.
  • Associated microcalcifications have been reported.
