| developmental psychology | The study of the psychological, physiological, and behavioural changes in an organism that occur from birth to old age. (05 Mar 2000) |
| arachnoid cysts | Fluid-filled sacs between the layers of the pia mater and arachnoid. These lesions, which often mimic intracranial neoplasms, present clinically at all ages but are probably congenital in origin. (12 Dec 1998) |
| 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) |
| 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) |
