    Intra-arterial mammographic calcification (MIAC) is uncommon, primarily affecting older individuals. Diabetes and hypertension appear to increase the likelihood of MIAC occurrence, suggesting a link to arteriosclerosis risk factors.

    Area of Science:

    • Radiology
    • Cardiovascular Health
    • Geriatric Medicine

    Background:

    • The clinical significance of intra-arterial mammographic calcification (MIAC) remains debated.
    • MIAC is an incidental finding on mammograms, requiring further investigation into associated risk factors.

    Purpose of the Study:

    • To investigate the prevalence of MIAC in a patient cohort.
    • To identify potential risk factors, specifically focusing on arteriosclerosis indicators like hypertension, diabetes, and age, associated with MIAC.

    Main Methods:

    • Retrospective analysis of mammograms from 914 patients.
    • Statistical review of patient data to correlate MIAC presence with hypertension, diabetes, and age.

    Main Results:

    Related Experiment Videos

  • MIAC was identified in 78 out of 914 patients (approximately 8.5%).
  • 83% of patients with MIAC were aged 60 years or older.
  • Among patients with MIAC, 37% had both diabetes and hypertension, 23% had diabetes only, and 64.6% of those over 60 also had diabetes.

    • Conclusions:

    • MIAC is an infrequent finding, predominantly observed in elderly patients.
    • The presence of diabetes and hypertension appears to be a predisposing factor for MIAC, highlighting a potential association with arteriosclerosis.
