| hilum of lung | A wedge-shaped depression on the mediastinal surface of each lung, where the bronchus, blood vessels, nerves, and lymphatics enter or leave the viscus. Synonym: hilum pulmonis, porta pulmonis. (05 Mar 2000) |
|---|---|
| secondary lung cancer | The spread of cancerous tumours from a distant organ to the lung. Due to the lungs tremendous blood and lymphatic supply it is a frequent site for metastatic cancer. Cancers which commonly metastasize to the lung include osteosarcoma, breast cancer, neuroblastoma, Wilm's tumour and non-Hodgkin's lymphomas. (27 Sep 1997) |
| honeycomb lung | <radiology> Mnemonic: honey and SPICE, sarcoid, pneumoconiosis, interstitial fibrosis, collagen-vascular disease, eosinophilic granuloma, ** see also: interstitial lung disease, honeycombing (12 Dec 1998) |
| pump lung | In shock, the development of oedema, impaired perfusion, and reduction in alveolar space so that the alveoli collapse. Synonym: pump lung, wet lung, white lung. (05 Mar 2000) |
| horizontal fissure of right lung | The deep fissure that separates the upper and middle lobes of the right lung. Synonym: fissura horizontalis pulmonis dextri, horizontal fissure of right lung, minor fissure. (05 Mar 2000) |
| human embryo lung cell | <cell culture> Diploid, untransformed cells from the lungs of human embryos which are used to make vaccines against certain viruses (such as rabies). (09 Oct 1997) |
| shock lung | In shock, the development of oedema, impaired perfusion, and reduction in alveolar space so that the alveoli collapse. Synonym: pump lung, wet lung, white lung. (05 Mar 2000) |
| 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) |
| 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) |
