|---|---|
| emphysematous | <medicine> Pertaining to, or of the nature of, emphysema; swelled; bloated. Origin: Cf. F. Emphysemateux. Source: Websters Dictionary (01 Mar 1998) |
| emphysematous cholecystitis | <radiology> Ring of air in RUQ, Differential diagnosis: pneumatosis coli, lipomatosis of gall bladder (rare!), follow plain X-ray with ultrasound, males (3:1), especially diabetics, usually acalculous, high mortality (12 Dec 1998) |
| emphysematous cystitis | Inflammation of the bladder wall caused by gas-forming bacteria, usually secondary to diabetes mellitus. (05 Mar 2000) |
| emphysematous gangrene | <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) |
| emphysematous gastritis | <radiology> Rare but severe form of widespread phlegmonous gastritis secondary to, mucosal disruption, ingestion of toxic/corrosive substances (most common), alcohol abuse, trauma, gastric infarction, necrotizing enterocolitis, ulcer X-ray: linear small gas bubbles within grossly thickened wall, may be associated with gas in the portal vein prognosis: leads to cicatrical stenosis, 60-80% mortality (12 Dec 1998) |
| emphysematous phlegmon | <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) |
| 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. (05 Mar 2000) |
| congenital lobar emphysema | <radiology> Caused by bronchial cartilage abnormality, SOLID mass at birth: dilated alveoli filled with foetal lung fluid, usually in UPPER lobes (including RML), Treatment: surgical lobectomy Cf: cystic adenomatoid malformation (12 Dec 1998) |
| cutaneous emphysema | The presence of air in the subcutaneous tissue, may be seen in cases of pneumothorax. (27 Sep 1997) |
| 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) |
| senile emphysema | Emphysema consequent upon the physiologic atrophy of old age. (05 Mar 2000) |
