| hyperlucent lung | The radiographic finding that a lung or portion thereof is less dense than normal, as from air trapping by a bronchial foreign body, asymmetric emphysema, or decreasing blood flow. See: unilateral hyperlucent lung. (05 Mar 2000) |

| silo-filler's lung | Pulmonary oedema, usually delayed for 1-4 hours, occurring in an individual exposed to silage, probably due to nitrogen dioxide; can progress to bronchiolitis obliterans. (05 Mar 2000) |
| small cell lung cancer | A type of lung cancer in which the cells are small and round. Also called oat cell lung cancer. (12 Dec 1998) |
| nonsmall cell lung cancer | A general classification for squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. (12 Dec 1998) |
| superior lobe of lung | The lobe of the right lung that lies above the oblique and horizontal fissures and includes the apical, posterior and anterior bronchopulmonary segments; in the left lung, the lobe lies above the oblique fissure and contains the apicoposterior, anterior, superior lingular and inferior lingular segments. Synonym: lobus superior pulmonis, upper lobe of lung. (05 Mar 2000) |
| drug-induced eosinophilic lung disease | <radiology> Diffuse reticular pattern: nitrofurantoin, Loeffler-like pattern: penicillin, sulfonamides, ASA, para-ASA, imipramine, HCTZ, cromolyn sodium see: eosinophilic lung disease (12 Dec 1998) |
| drugs toxic to lung | <radiology> Bleomycin, methotrexate, cytoxan, amiodarone (12 Dec 1998) |
| dynamic compliance of lung | The value obtained when lung compliance is estimated during breathing by dividing the tidal volume by the difference in instantaneous transpulmonary pressures at the ends of the respiratory excursions, when flow in the airway is momentarily zero; this value deviates markedly from static compliance in patients in whom resistances and compliances are not uniform throughout the lung (i.e., uneven time constants). (05 Mar 2000) |
| quiet lung | The collapse of a lung during thoracic operations undertaken to facilitate surgical procedure through absence of lung movement. (05 Mar 2000) |
| inferior border of lung | The sharp border of the lung that separates the diaphragmatic surface from the costal and mediastinal surfaces. Synonym: margo inferior pulmonis. (05 Mar 2000) |
| inferior lobe of lung | It is located below and behind the oblique fissure and contains five bronchopulmonary segments: superior, medial basal, anterior basal, lateral basal, and posterior basal. Synonym: lobus inferior pulmonis, lower lobe of lung. (05 Mar 2000) |
| interlobar surfaces of lung | The pulmonary surfaces in the interlobar fissures of the lung. Synonym: facies interlobares pulmonis. (05 Mar 2000) |
| interstitial lung disease | <chest medicine> A group of lung disorders which result in scarring and dysfunction of the alveolus (air sac) in the lung. This results in poor oxygen diffusion from the air into the bloodstream. Widespread inflammation in the lung leads to fibrosis (scarring). Causes include chronic exposure to organic and inorganic dusts, fumes, vapors, radiation, medications and certain lung infections. Examples include asbestosis, silicosis, coal worker's pneumoconiosis and diffuse interstitial fibrosis. Smoking increases the risk in all cases. (27 Sep 1997) |
| interstitial lung disease with increased volume | <radiology> Cystic fibrosis (CF), eosinophilic granuloma (EG), lymphangioleiomyomatosis (LAM) (12 Dec 1998) |
| iron lung | A mechanical respirator in which the body except the head is encased within a metal tank, which is sealed at the neck with an airtight gasket; artificial respiration is induced by making the air pressure inside negative. Synonym: iron lung, tank respirator. (05 Mar 2000) |
