Benign breast lumps like hamartoma, lipoma, and fat necrosis can often be diagnosed via mammography. Distinctive imaging features allow for non-invasive diagnosis, potentially avoiding biopsy.

Area of Science:

  • Radiology
  • Pathology
  • Oncology

Background:

  • Benign fatty tissue lesions, including hamartoma, lipoma, and fat necrosis, are common causes of breast lumps.
  • Mammographic evaluation plays a crucial role in the initial assessment of breast abnormalities.

Purpose of the Study:

  • To describe the characteristic mammographic appearances of benign fatty breast lesions.
  • To highlight imaging features that may allow for diagnosis without the need for biopsy.

Main Methods:

  • Review of mammographic findings for confirmed cases of hamartoma, lipoma, and fat necrosis.
  • Correlation of imaging features with histopathological diagnoses where available.

Main Results:

  • Hamartomas present as compressible masses with mixed radiolucent fat and dense fibrous tissue, enclosed by a pseudocapsule.

  • Lipomas are typically radiolucent with well-defined, smooth capsules.
  • Fat necrosis can manifest as oil cysts with egg-shell calcification in 27% of cases.

    • Conclusions:

    • Distinctive mammographic features of benign fatty breast lesions can facilitate accurate diagnosis.
    • Imaging-based diagnosis may obviate the need for biopsy in select cases of hamartoma, lipoma, and fat necrosis.
