| intralobar sequestration | <radiology> Nonfunctioning portion of lung <indent>WITHIN visceral pleura of a pulmonary lobe, left lower lobe (67%); rarely in upper lobes, arterial supply: SYSTEMIC, usually aorta, venous drainage: usually via pulmonary. Vv. (occasionally systemic), usually does not communicate with bronchial tree, cystic, may become infected, not associated with other abnormalities see: sequestration Cf: extralobar sequestration (12 Dec 1998) |

| intralobar | Within a lobe of any organ or other structure. (05 Mar 2000) |
|---|---|
| intralobar part of the right superior pulmonary vein | <anatomy, vein> The vein draining the apical and posterior segments of the right lung; tributary to the posterior branch of the right superior pulmonary vein. Synonym: pars intralobaris venae pulmonalis dextrae superioris. (05 Mar 2000) |
| bronchopulmonary sequestration | A developmental anomaly in which a mass of nonfunctioning lung tissue lacks normal connection with the tracheobroncheal tree and receives an anomalous blood supply originating from the descending thoracic or abdominal aorta. The mass may be extralobar, i.e., completely separated from normally connected lung, or intralobar, i.e., partly surrounded by normal lung. (12 Dec 1998) |
| sequestration | 1. Formation of a sequestrum. 2. Loss of blood or of its fluid content into spaces within the body so that it is withdrawn from the circulating volume, resulting in haemodynamic impairment, hypovolaemia, hypotension, and reduced venous return to the heart. Origin: L. Sequestratio, fr. Sequestro, pp. -atus, to lay aside (05 Mar 2000) |
| sequestration cyst | A collection of cancerous cells which form cysts that contain one or more of the three primary embryonic germ layers: skin, hair or teeth. (27 Sep 1997) |
| sequestration dermoid | An obsolete term for epidermal cyst. (05 Mar 2000) |
| disc sequestration | <radiology> Complete separation of disc material with rupture through posterior longitudinal ligament into the epidural space; free fragment herniation findings: migration superiorly/inferiorly with compression of nerve roots above/below the level of herniation, disc material noted more than 9mm from disc space Differential diagnosis: postoperative scarring (retraction of thecal sac to the site of surgery), epidural abscess/tumour, conjoined nerve root: 2 nerve roots arising simultaneously from the thecal sac; normal variant in 1-3% see: degenerative disc disease (12 Dec 1998) |
| extralobar sequestration | <radiology> Accessory lung: lung tissue in its own pleura, left lower lobe (90%), systemic arterial AND venous connection (unlike intralobar) results in L to R shunt, associated with congenital anomalies of diaphragm: eventration, paralysis, ipsilateral hernia, XR: homogeneous ST mass, rarely infected see also: sequestration Cf: intralobar sequestration (12 Dec 1998) |
