The Normal Aging Chest: An Overview of Radiologic Imaging Features
Many age-related morphologic changes are revealed in radiologic images of the chest in the elderly. We categorize the aging chest according to changes in the lung, airways, mediastinum, chest wall, and diaphragm. Changes in the lung include age-related alveolar hyperinflation, ground-glass opacity i...

| description | Many age-related morphologic changes are revealed in radiologic images of the chest in the elderly. We categorize the aging chest according to changes in the lung, airways, mediastinum, chest wall, and diaphragm. Changes in the lung include age-related alveolar hyperinflation, ground-glass opacity in basal dependent lungs, mosaic attenuation pattern, reticular densities in basal subpleural lungs, small nodule, air cyst, and apical cap. Changes in the airway include the tracheobronchial wall cartilage calcification, increased anterior-posterior diameter of the trachea, increased bronchoarterial ratio and bronchial wall thickness. Mediastinum changes include cardiac enlargement, coronary and cardiac valve/annulus calcification, aorta dilation and wall calcification, and excessive fat deposition. The chest wall shows decreased muscle mass, osteophytes, rib cartilage calcifications, and increased thoracic anterior-posterior diameter. The diaphragm changes include bulging contour, diaphragm defect, and esophageal hiatal hernia. Radiologists should therefore be aware of the age-related changes in the elderly chest. Differentiation between normal age-related changes and clinically significant disease is essential in the interpretation of chest radiologic images. |
