Summary

Thoracic calcification is highly prevalent in the elderly, affecting the aorta, costal cartilage, and lung parenchyma. The degree of calcification varies by tissue and sex, with less clinical significance in older individuals.

Area of Science:

  • Radiology
  • Geriatric Medicine
  • Anatomy

Background:

  • Thoracic calcification is a common finding in medical imaging.
  • Its prevalence and patterns in the very elderly population require detailed investigation.

Purpose of the Study:

  • To analyze the frequency and distribution of thoracic calcifications in patients aged 90-102 years.
  • To determine the relationship between calcification, tissue type, and sex.
  • To discuss the clinical implications and differential diagnosis of these findings.

Main Methods:

  • Retrospective analysis of chest X-ray films from 200 elderly patients (90-102 years old).
  • Assessment of calcification in the aortic wall, costal cartilage, lung parenchyma, hilum/mediastinum, and tracheobronchial cartilages.

  • Statistical analysis to evaluate the degree of calcification based on tissue and sex.

    • Main Results:

    • High prevalence of thoracic calcification observed: aortic wall (89%), costal cartilage (79%), lung parenchyma (65%), hilum/mediastinum (64%), tracheobronchial cartilages (55%).
    • Significant differences in calcification degree were noted across tissues and between sexes (p < 0.001).
    • Calcification generally holds less clinical value in the elderly compared to younger patients.

    Conclusions:

    • Thoracic calcification is nearly universal in the very elderly, with specific patterns related to anatomical location.
    • Sex and tissue type are significant determinants of calcification severity.
    • Understanding these patterns is crucial for accurate interpretation, though clinical relevance may be diminished in extreme old age.
