| 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) |

| 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 Loss of blood or of its fluid content into spaces within the body so that it is withdrawn from the circulating volume, resulting in haemodynamic impairment, hypovolaemia, hypotension, and reduced venous return to the heart.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) |
| 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) |
| 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) |
| annulus fibrosus of intervertebral disc | The ring of fibrocartilage and fibrous tissue forming the circumference of the intervertebral disc; surrounds the nucleus pulposus, which is prone to herniation when the annulus fibrosus is compromised. Synonym: annulus fibrosus disci intervertebralis, annulus fibrosus, fibrous ring of intervertebral disc, fibrous ring. (05 Mar 2000) |
| articular disc | A plate or ring of fibrocartilage attached to the joint capsule and separating the articular surfaces of the bones for a varying distance, sometimes completely; it serves to adapt two articular surfaces that are not entirely congruent. Synonym: discus articularis, articular disk, fibrocartilago interarticularis, fibroplate, interarticular fibrocartilage, intra-articular cartilage. (05 Mar 2000) |
| articular disc of acromioclavicular joint | The articular disk of fibrocartilage usually found between the acromial end of the clavicle and the medial border of the acromion. Synonym: discus articularis acromioclavicularis, acromioclavicular disk, Weitbrecht's cartilage. (05 Mar 2000) |
| articular disc of distal radioulnar joint | The disk that holds together the distal ends of the radius and ulna; it is attached by its apex to a depression between the styloid process and distal surface of the head of the ulna, and by its base to the ridge separating the ulnar notch from the carpal surface of the radius. Synonym: discus articularis radioulnaris, radioulnar disk, radioulnar articular disk, triangular cartilage, triangular disk of wrist, triquetrous cartilage. (05 Mar 2000) |
| articular disc of sternoclavicular joint | The fibrocartilaginous disk that subdivides the sternoclavicular joint into two cavities. Synonym: discus articularis sternoclavicularis, sternoclavicular disk, sternoclavicular articular disk. (05 Mar 2000) |
| articular disc of temporomandibular joint | The fibrocartilaginous plate that separates the joint into upper and lower cavities. Synonym: discus articularis temporomandibularis, mandibular disk, temporomandibular articular disk. (05 Mar 2000) |
| bulging disc | <radiology> Broad-based disc extension outward in all directions with intact but weakened annulus fibrosus and posterior longitudinal ligament, age: greater than40 y.o (common finding), location: lumbar, cervical findings: concave anterior margin of thecal sac, nucleus pulposa hypointense on T1 and hyperintense on T2 (water loss through degeneration) see: degenerative disc disease (12 Dec 1998) |
| cervical disc herniation | <radiology> C6-7 (69%), C5-6 (19%), C7-T1 (10%), C4-5 (2%) see: degenerative disc disease (12 Dec 1998) |
| cervical disc syndrome | <syndrome> Pain, paresthesias, and sometimes weakness in the area of the distribution of one or more cervical roots, due to pressure of a protruded cervical intervertebral disc. Synonym: cervical compression syndrome. (05 Mar 2000) |
