[Thoracic calcification in the elderly--frequency and clinical value]

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.
