Change of thoracic cage contour-barrel chest, Flatten of ribs, Increases of intercostal space, Diaphragm flatten and decrease in level, Increase of lung transparency and sparse of lung markings, unilateral-Shift of mediastium. ⚫ Ateletasis: Contraction of thoracic cage, Elevation of affected diaphragm, Mediastium shift, compensatory emphysema, Increase attenuation and volume loss of affected lobe. Specific features of lobe ateletasis: Obstructive inflammation, Recurrent inflammation of the same lobe/segmen, Not reactive to antibiotics. ⚫ Exudation: inflammatory exudation, alveolar bleeding, Soft-tissue density shadow, Irregular margin, only restrained by fissures, homogeneous(consolidation) or inhomogeneous, survive of bronchi lumen: air-bronchogram. ⚫ Cavity: when necrotic substance is drained from the lesion through airway, and residual aircontaining structure is called cavity. Thin wall cavity (wall less than 3mm), usu. with clear lining, caused by TB, Thick wall cavity (wall more than 3mm), eccentric lumen with irregular or nodular lining: cancer, shaggy lining: lung abscess, smooth lining: tuberculosis, Cavity without wall (caseous cavity, wormbit cavity), Intrapulmonary air containing space: ⚫ Abnormal dilation of part of airway. e.g. lung cyst, bullae. very thin wall, usu. less than 1mm, clear lining, may seen air-fluid level when infected. 10’ 10’ 5’ 10’ 5’
