| bone cysts | Pathological bone spaces in the metaphyses of long bones of growing children. They are of disputed origin. Cysts may be either empty or filled with fluid and have a delicate connective tissue lining. (12 Dec 1998) |
|---|---|
| bone cysts, aneurysmal | Solitary lesions of bone that typically cause a bulging of the overlying cortex bearing some resemblance to the saccular protrusion of the aortic wall in aortic aneurysm, hence the name. (12 Dec 1998) |
| paraphysial cysts | Cyst's arising from vestigial remnants of the paraphysis; they are the possible origin of some third ventricular colloid cyst's. (05 Mar 2000) |
| glomerular cysts | Cyst's formed by dilatation of Bowman's capsules, found in rare cases of congenital polycystic kidneys. (05 Mar 2000) |
| congenital renal cysts | <radiology> Congenital solitary cyst, multilocular cyst, multicystic disease (renal dysplasia), polycystic disease, autosomal-recessive (childhood) form, autosomal-dominant (adult) form, medullary sponge kidney, medulary cystic disease see also: Potter syndrome (12 Dec 1998) |
| multiple renal cysts | <radiology> Adult (autosomal-dominant) polycystic kidney disease, multiple simple cysts, tuberous sclerosis, von Hippel-Lindau syndrome, Meckel-Gruber syndrome (12 Dec 1998) |
| 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) |
