Nonspecific interstitial pneumonia Predominant posterior and basal lung, sparing the immediate subpleural lung, Reticulation, traction bronchiectasis and bonchiolectasis, Honeycombing. Ground-glass opacity, CT features? Collagen vascular disease as scleroderma, and other collagen disease (UIP, NSIP, BOOP) Rheumatoid lung, lung disease? Active pulmonary sarcoidosis CT features? Upperlobe predominance, Hilar, mediastinal nodes, Ground-glass opacity, small granulomas. Perilymphatic nodules, Patchy, End-stage sarcoidosis? Irregular septal thickening, Architetural distortion, Parahilar conglomerate, honeycombing, Hilar, mediastinal nodes. Silicosis and Coal Worker's pneumoconiosis? distribution, Posterior lung predominance, Upper lobe predominance, Conglomerate masses, Hilar, mediastinal nodes (egg-shell calcification). Perilymphatic nodules, Symmetric PulmonaryEndobronchial spread (centrilobular nodules, tree-in-bud, focal areas of consolidation, bronchial wall thickening or bronchiectasis, pathcy or focal), Miliary spread (random nodules, 1-5 mm, Usually diffuse). Tuberculosis CT features? PulmonaryFilling of proteinosis? alveolar alveolar spaces with lipid-rich proteinaceous material, Patchy or geographic ground-glass opacity, smooth, interlobular septal thickening in ground-glass--"crazy paving"". Hypersensitivity pneumonitis, subacute stage CT features? Patchy or geographic ground-glass opacity, Poorly defined centrilobular nodules or ground-glass opacity, Mosaic perfusion, Air trapping. Bronchiolitis obliterans infections, pneumonia, causes? reactions, autoimmune disease. Idiopathic, organizing toxic exposures, drug HRCT features of bronchiolitis obliterans organizing pneumonia? Patchy or nodular consolidation, Patchy or nodular ground-glass opacity, Peripheral and peribronchial distribution. Chronic eosinophilicalveoli by mixed inflammatory infiltrate (eosinophils), similar to BOOP--patchy consolidation or ground-glass, peripheral distribution. Filling of pneumonia? Histiocytosis (aka Langerhans histiocytosis or eosinophilic granuloma)? lung cysts, Normal appearing intervening lung, Upper lobe predominance, Spares costophrenic angles. Centrilobular nodules (may cavitate), Thin-walled, irregular Lymphangiomyomatosis? bearing age, can occur in Tuberous sclerosis, too, Thin-walled, round lung cysts, Normal-appearing intervening lung, Lymph node enlargement, Diffuse distribution without sparing lung bases. Women of child List 4 types of emphysema? lobes, smokers, most common form), Panlobular (less common, alpha1-antitrypsin, most severe at lung bases), Paraseptal (subpleural lung, adjacent to chest wall and mediastinum), Bullous (Large bullae, young men). Centrilobular (upper Split pleura sign? Thickened visceral and parietal pleural layers are split apart and surround an empyema. Extension of an empyema to involve the chest wall is termed? empyema necessitatis. Lung abscess versus empyema CT characteristics? Abscess (poorly defined, irregular wall, spherical, multiple cavities, acute angles, vessels not displaced), Empyema (well defined, smooth, uniform wall, elliptical, split pleura, acute or obtus angles, vessels displaced). CT features of a malignant thickening, pleural thickness > 1 cm, concentrically involves the pleura, encasing the lung, thickening of mediastinal pleura. Nodular pleural effusion? CT findings for chest wall invasion? tumor and chest wall (> 3cm or ratio > 0.7), Obtuse angles, Chest wall mass, Bone...
