| bronchial provocation tests | Tests involving inhalation of allergens (nebulised or in dust form), nebulised pharmacologically active solutions (e.g., histamine, methacholine), or control solutions, followed by assessment of respiratory function. These tests are used in the diagnosis of asthma. (12 Dec 1998) |

| bronchial respiration | A tubular blowing sound caused by the passage of air through a bronchus in an area of consolidated lung tissue. (05 Mar 2000) |
| bronchial spasm | Spasmodic contraction of the smooth muscle of the bronchi. (12 Dec 1998) |
| bronchial tubes | <anatomy> The bronchial tubes which arise from the branching of the trachea, especially. The subdivision of the bronchi. Origin: L, pl. Cf. Bronchus. Source: Websters Dictionary (01 Mar 1998) |
| bronchial veins | Many veins running in front of and behind the bronchi and uniting into two main trunks which empty on the right side into the azygos vein, on the left into the accessory hemiazygos or the left superior intercostal vein. Synonym: venae bronchiales. (05 Mar 2000) |

| trans-bronchial biopsy | <chest medicine, procedure> A biopsy that is performed through the wall of the bronchus (using the bronchoscope). This involves obtaining a small piece of lung tissue for microscopic analysis. This is a useful alternative to an open surgical biopsy, where an incision must be made. (17 Mar 1998) |
| adrenal cyst | <radiology> Same characteristics as renal cysts, but less common, thick wall, septations, calcifications suggests pseudocyst (12 Dec 1998) |
| adventitious cyst | 1. An accumulation of fluid in a cystlike loculus, but without an epithelial or other membranous lining. Synonym: adventitious cyst, false cyst. 2. A cyst whose wall is formed by a host cell and not by a parasite. 3. A mass of 50 or more Toxoplasma bradyzoites, found within a host cell, frequently in the brain; formerly called a pseudocyst, but now considered a true cyst enclosed in its own membrane within the host cell that may rupture to release particles that form new cysts, and apparently is infective to another vertebrate host. See: bradyzoite. Origin: pseudo-+ G. Kystis, bladder (05 Mar 2000) |
| allantoic cyst | Cyst occurring in a persistent portion of the urachus, presenting as an extraperitoneal mass in the umbilical region. It is characterised by abdominal pain, and fever if infected. It may rupture, leading to peritonitis, or it may drain through the umbilicus. (12 Dec 1998) |
| alveolar hydatid cyst | A hydatid cyst of a multiloculate type, usually in the liver, caused by Echinococcus multilocularis, adults of which are in foxes; larvae (alveolar hydatid) are found chiefly in microtine rodents, but also among humans such as trappers and others handling pelts of infected foxes and other carnivores; growth is by exogenous budding and is not limited by an outer laminated membrane as in the hydatid cyst from E. Granulosus; necrosis, cavitation, contiguous spread, and death usually ensue. Synonym: multilocular hydatid cyst, multiloculate hydatid cyst. (05 Mar 2000) |
| aneurysmal bone cyst | <radiology> ABC, 10 - 30 yrs, 75% before skeletal maturity, sites: long bones; also, flat bones Findings: metaphyseal if unfused, metaepiphyseal after fusion, lytic, expansile, thin, continuous rim, thin internal bony strands (12 Dec 1998) |
| angioblastic cyst | Mesenchymal tissue capable of forming blood in the embryo. (05 Mar 2000) |

| apoplectic cyst | A pseudocyst formed of extravasated blood as in a stroke. (05 Mar 2000) |
