| fibrosing alveolitis | A progressive inflammatory condition starting with diffuse alveolar damage and resulting in fibrosis and honeycombing over a variable time period; also a common feature of collagen-vascular diseases. Synonym: fibrosing alveolitis, Hamman-Rich syndrome, idiopathic interstitial fibrosis. (05 Mar 2000) |
|---|
| chronic fibrosing alveolitis | <radiology> Aka: usual interstitial pneumonia (UIP), 5-6th decade; M:F = 1:1, clubbing of fingers (83%), lymphocytosis on lavage, increased occurence of bronchogenic CA, average survival of 4-6 years; 87% mortality CXR findings: occasional ground glass pattern in early stage of alveolitis, diffuse reticulations (60%) predominantly at bases, honeycombing, pleural effusion (4%); pleural thickening (6%), pneumothorax in 7% (late stage), progressive volume loss see: interstitial pulmonary fibrosis (12 Dec 1998) |

| fibrosing adenomatosis | A nodular, benign breast lesion occurring most frequently in relatively young women and consisting of hyperplastic distorted lobules of acinar tissue with increased collagenous stroma; the changes may be difficult to distinguish microscopically from carcinoma. Also, a benign nodular microscopic lesion of the prostate consisting of acimar tissue with increased stroma; the basal cell layer shows characteristic smooth muscle metaplasia. Synonym: adenofibrosis, fibrosing adenomatosis, fibrosing adenosis. (05 Mar 2000) |

Synonym: adenofibrosis, fibrosing adenomatosis, fibrosing adenosis. (05 Mar 2000) |
| fibrosing mediastinitis | <radiology> Histoplasmosis most common cause, can cause superior vena cava obstruction (12 Dec 1998) |
| acute extrinsic allergic alveolitis | <radiology> No chest X-ray findings in 30-95%, diffuse acinar consolidative pattern (oedema and exudative filling of alveoli), basilar distribution, lymph node enlargement (unusual, more common with recurrence) see: extrinsic allergic alveolitis (12 Dec 1998) |
| acute pulmonary alveolitis | Acute inflammation involving exudate into the pulmonary alveoli and impaired gas exchange; may result in necrosis with haemorrhage into the lungs; occurs in Goodpasture's syndrome, in association with a glomerulonephritis. (05 Mar 2000) |
| allergic alveolitis | <chest medicine> Inflammation of the lungs which occurs secondary to exposure to a chemical, organic dust, fungus or mould. Chronic exposure can lead to chronic lung changes evident on chest X-ray. Symptoms include cough, fever, shortness of breath and wheezing. See: bird-handler's disease. (27 Sep 1997) |
| alveolitis | <pathology> Inflammation of an alveolus. Synonym: odontobothritis. (18 Nov 1997) |
| alveolitis, extrinsic allergic | Conditions in which inhalation of organic dusts results in hypersensitivity reactions at the alveolar level, associated with the production of precipitins. (12 Dec 1998) |
| extrinsic allergic alveolitis | <radiology> Exposure to organic dust less than 5u in size, recurrent episodes of fever, chills, dry cough, dyspnea following exposure after 6 hr interval (10-40% assymptomatic), spontaneous resolution in 1-2 days, farmer's lung, Pandora's pneumonitis, bird-fancier's lung, mushroom worker's lung, bagassosis, malt worker's lung, maple bark disease, suberosis, sequoiosis see: acute extrinsic allergic alveolitis, hypersensitivity pneumonitis (12 Dec 1998) |
