| corpora lutea cysts | Persistent corpora lutea with cyst formation. (05 Mar 2000) |
|---|---|
| cysts | Any closed cavity or sac, normal or abnormal, lined by epithelium, and especially one that contains a liquid or semisolid material. (12 Dec 1998) |
| cysts by ultrasound | <radiology> Defined by three properties (all must be present): anechoic lumen, sharp posterior margin, posterior acoustic enhancement (12 Dec 1998) |
| hepatic cysts | Congenital cyst's thought to originate from an obstruction of biliary ductules; they may be solitary and range in size from small to enormous; polycystic disease may also occur. (05 Mar 2000) |
| neurenteric cysts | Paravertebral cysts commonly connected to the meninges or a portion of the gastrointestinal tract that develop due to incomplete separation of endoderm from the notochord during early foetal life; often symptomatic. (05 Mar 2000) |
| iodine cysts | An obsolete term used to indicate the cyst's of Iodamoeba butschlii, characterised by a large iodine-positive glycogen vacuole. (05 Mar 2000) |
| odontogenic cysts | Cysts found in the jaws and arising from epithelium involved in tooth formation. They include follicular cysts (e.g., primordial cyst, dentigerous cyst, multilocular cyst), lateral periodontal cysts, and radicular cysts. They may become keratinised (odontogenic keratocysts). Follicular cysts may give rise to ameloblastomas and, in rare cases, undergo malignant transformation. (12 Dec 1998) |
| ovarian cysts | General term for cysts and cystic diseases of the ovary. (12 Dec 1998) |
| enterogenous cysts | Mediastinal cysts derived from cells sequestered from the primitive foregut; may be classified histologically as bronchogenic, oesophageal, or gastric. (05 Mar 2000) |
| jaw cysts | Saccular lesions lined with epithelium and contained within pathologically formed cavities in the jaw; also nonepithelial cysts (pseudocysts) as they apply to the jaw, e.g., traumatic or solitary cyst, static bone cavity, and aneurysmal bone cyst. True jaw cysts are classified as odontogenic or nonodontogenic. (12 Dec 1998) |
| foregut cysts | <radiology> Bronchogenic and enteric cysts: more common on the right, neurenteric cysts: associated with vertebral anomalies, enteric cysts: may contain acid-secreting gastric mucosa;, confirm with TcO4 scan (12 Dec 1998) |
| acute vascular occlusion | <cardiology, surgery> A serious condition that results from the sudden blockage of an artery, usually with a blood clot. (27 Sep 1997) |
| acute vascular purpura | <dermatology> This relatively rare disorder is characterised by skin purpura, joint pains, abdominal pain and renal disease (glomerulonephritis). Although Henoch-Schonlein purpura or anaphylactoid purpura, is thought to be a immune complex mediated disease, its exact cause is unknown. Its typical benign coarse can, however, include renal failure. (27 Sep 1997) |
| articular vascular circle | An anastomosis of vessels encircling a joint. See: articular vascular network. Synonym: circulus articularis vasculosus. (05 Mar 2000) |
| articular vascular network | A vascular rete in the neighborhood of a joint, where such arrangements are common, enabling a collateral circulation by which blood will be supplied distal to the joint regardless of compromises resulting from joint position. Synonym: circulus articularis vasculosus, rete vasculosum articulare, articular network. (05 Mar 2000) |
