| interstitial emphysema | Presence of air in the pulmonary tissues consequent upon rupture of the air cells, presence of air or gas in the connective tissue. (05 Mar 2000) |
|---|---|
| pulmonary emphysema | Condition of the lungs characterised by increase beyond normal in the size of air spaces distal to the terminal bronchioles, either from dilatation of the alveoli or from destruction of their walls. (12 Dec 1998) |
| diffuse interstitial pulmonary fibrosis | This represents a group of pulmonary disorders (lower respiratory tract) that leads to a functional loss in the alveolar air sacs and a compromise in the diffusion of oxygen from air to blood. There is widespread inflammation and scar tissue (fibrosis) formation within the lung. The causes are varied and include: inorganic and organic dusts, gases, fumes, vapors, infections, radiation, medications, coal dust, silicosis and byssinosis. When the cause is not identifiable it is referred to as idiopathic diffuse interstitial pulmonary fibrosis (27 Sep 1997) |
| interstitial pulmonary fibrosis | <radiology> Idiopathic, idiopathic pulmonary fibrosis (AKA: usual interstitial pneumonitis), Hamman-Rich syndrome (rapidly progressive), drug-related, collagen-vascular disease, rheumatoid lung disease, scleroderma (12 Dec 1998) |
| alveolar duct emphysema | Emphysema in which the primary involvement is in the alveolar ducts and respiratory bronchioles, as opposed to panacinar emphysema. (05 Mar 2000) |
| bullous emphysema | Emphysema in which the enlarged airspaces are one to several cm in diameter, often visible on chest radiographs. Thin-walled air sacs under tension compress pulmonary tissue, either single or multiple. Sometimes amenable to surgical resection with improvement in pulmonary function. (05 Mar 2000) |
| gangrenous emphysema | <microbiology> A severe form of gangrene (tissue necrosis) caused by Clostridium infection. Also referred to as necrotising subcutaneous infection. Results in death of the subcutaneous tissues and muscle layers. See: necrotising fascitis. (27 Sep 1997) |
| panacinar emphysema | Emphysema affecting all parts of the lobules, in part, or usually the whole, of the lungs, and usually associated with a1-antiprotease deficiency emphysema. Synonym: diffuse emphysema, generalised emphysema, panacinar emphysema. (05 Mar 2000) |
| panlobular emphysema | Emphysema affecting all parts of the lobules, in part, or usually the whole, of the lungs, and usually associated with a1-antiprotease deficiency emphysema. Synonym: diffuse emphysema, generalised emphysema, panacinar emphysema. (05 Mar 2000) |
| generalised emphysema | Emphysema affecting all parts of the lobules, in part, or usually the whole, of the lungs, and usually associated with a1-antiprotease deficiency emphysema. Synonym: diffuse emphysema, generalised emphysema, panacinar emphysema. (05 Mar 2000) |
| paraseptal emphysema | Emphysema involving the periphery of the pulmonary lobules. (05 Mar 2000) |
| mediastinal emphysema | Presence of air in the mediastinal tissues due to leakage of air from the tracheobronchial tree, usually as a result of trauma. (12 Dec 1998) |
| centri-acinar emphysema | Emphysema affecting the lobules around their central bronchioles, causally related to bronchiolitis, and seen in coal-miner's pneumoconiosis. Synonym: centri-acinar emphysema. (05 Mar 2000) |
| centrilobular emphysema | Emphysema affecting the lobules around their central bronchioles, causally related to bronchiolitis, and seen in coal-miner's pneumoconiosis. Synonym: centri-acinar emphysema. (05 Mar 2000) |
| compensating emphysema | Compensatory emphysema, increase in the air capacity of a portion of the lung when another portion is consolidated, shrunken, or unable to perform its respiratory function; the alveoli are distended, but there is no destruction of alveolar walls, and hence, no true emphysema, as this term is now defined.
