| bilateral adrenal mass | <radiology> Acute granulomatous disease (e.g., TB), metastases (bilateral in 15%), pheochromocytoma (bilateral in 10%), adrenal hyperplasia (adenoma), spontaneous adrenal haemorrhage (12 Dec 1998) |
| bilateral hermaphroditism | True hermaphroditism with an ovotestis on both sides. (05 Mar 2000) |
| bilateral hydronephrosis | <nephrology, urology> Refers to the bilateral enlargement of the renal pelvis and calyces of the kidneys. This is not a disease itself but a finding associated with a variety of disease states which interfere with the drainage of urine from the kidneys to the ureters and into the bladder. Examples include acute and chronic bilateral obstructive uropathy, vesicoureteric reflux, ureteropelvic junction obstruction, neurogenic bladder, bladder outlet obstruction and prune belly syndrome. (27 Sep 1997) |
| bilateral large kidneys | <radiology> Autosomal dominant (adult) polycystic disease, lymphoma Cf: other urographic patterns (12 Dec 1998) |
| bilateral left-sidedness | A syndrome in which normally unpaired organs develop more symmetrically in mirror image; two spleens, one on each side, are usually present, and cardiovascular anomalies are common. Synonym: polysplenia syndrome. (05 Mar 2000) |
| bilateral mastectomy | <procedure, surgery> The surgical removal of both breasts. (09 Oct 1997) |
| bilateral medial orbital ecchymoses | <clinical sign, ophthalmology> The appearance of the eyes produced by subconjunctival haemorrhage and/or periorbital ecchymosis. Synonym: bilateral medial orbital ecchymoses. (21 Jun 2000) |
| bilateral pleurisy | Inflammation of the pleura on both sides of the thorax. Synonym: double pleurisy. (05 Mar 2000) |
| bilateral symmetry | <biology> Describes an organism which is divisible into equal mirror halves in one plane only. (09 Oct 1997) |
| bilateral synchrony | Electroencephalographic activity that is recorded over both hemispheres simultaneously; usually used in reference to spike and wave activity. (05 Mar 2000) |
| parathyroids, hypoplasia of the thymusand | Also known as the digeorge syndrome (dgs), this disorder is characterised by (1) low blood calcium levels (hypocalcaemia) due to underdevelopment (hypoplasia) of the parathyroid glands which control calcium; (2) underdevelopment (hypoplasia) of the thymus, an organ behind the breastbone in which lymphocytes mature and multiply; and (3) defects of the heart involving the outflow tracts from the heart. most cases of dgs are due to a microdeletion in chromosome band 22q11.2. A small number of cases have defects in other chromosomes, notably 10p13. Named after the american paediatric endocrinologist angelo digeorge. Another name for dgs is the third and fourth pharyngeal pouch syndrome. (12 Dec 1998) |
| cartilage-hair hypoplasia | An autosomal recessive form of dwarfism characterised by shortness of the extremities without skull defects, and with sparse, brittle hair of light colour. There is a peculiar, not adequately explained severity in the clinical course of varicella and herpes in such patients. (05 Mar 2000) |
| right ventricular hypoplasia | A congenital or acquired condition in which there is thinning of the right ventricular myocardium. Synonym: right ventricular hypoplasia. (05 Mar 2000) |
