| Eisenmenger's defect | The combination of ventricular septal defect with pulmonary hypertension and consequent right-to-left shunt through the defect, with or without an associated overriding aorta. Synonym: Eisenmenger's defect, Eisenmenger's disease, Eisenmenger's tetralogy. (05 Mar 2000) |
|---|---|
| endocardial cushion defect | <radiology> Persistence of primitive atrioventricular canal and anomalies of AV valves associated with: Down syndrome: in 25% of Trisomy 21 an ECD is present; in 45% of ECD Trisomy 21 is present, asplenia/polysplenia types: complete (AV canal), partial findings: gooseneck deformity on angiogram, increased pulmonary vascularity, enlarged pulmonary artery, enlarged RV, LV, RA; normal LA (secondary to atrial septal defect) (12 Dec 1998) |
| enzyme defect | A disorder resulting from a deficiency (or functional abnormality) of an enzyme. In 1902 Archibald Garrod first attributed a disease to an enzyme defect: an inborn error of metabolism. Today, newborns are routinely screened for certain enzyme defects such as PKU (phenylketonuria) and galactosaemia, an error in the handling (metabolism) of the sugar galactose. (12 Dec 1998) |
| uterine filling defect | <radiology> Technical, bubble, blood clot, mucoid material, congenital fold, pseudoadhesions / ridging -- folds long axis, neoplasm, submucosal leiomyoma, adenoma, endometrial carcinoma, pregnancy-related, pregnancy, molar pregnancy, retained conceptus, polyp, septated uterus, synechiae, IUD, iatrogenic (post-op) (12 Dec 1998) |
| filling defect | Displacement of contrast medium by a space-occupying lesion in a radiographic study of a contrast-filled hollow viscus, such as a polyp on a barium enema; also applied to defects in the otherwise uniform distribution of radionuclide in an organ, such as a metastasis in the liver on a 99mTc-sulfur colloid scan. (05 Mar 2000) |
| filling defect in renal collecting system | <radiology> Common causes: transitional cell carcinoma, blood clot, lucent calculus (urate) less common causes: fungus ball, sloughed papilla, fibroepithelial polyp, invasion by hypernephroma, malakoplakia, vessel impression, metastases (12 Dec 1998) |
| lambdoid suture defect | <radiology> Well-defined lucent lesion, classically unilateral, associated with neurofibromatosis (12 Dec 1998) |
| luteal phase defect | Inadequate function of the corpus luteum that may prevent a fertilized egg from implanting in the uterus or may lead to early pregnancy loss. (09 Oct 1997) |
| adenoma, adrenal cortical | A benign neoplasm of adrenal cortical cells resembling normal adrenal cells histologically but possessing functional autonomy. In general it does not exceed 5 cm in its largest dimension, although benign tumours exceeding 20 cm have been reported. Adrenal cortical adenomas produce hypercortisolism and hyperaldosteronism, but seldom produce adrenogenital syndromes. For the most part the prognosis after surgery is reasonably favourable. (12 Dec 1998) |
| adrenal cortical carcinomas | Large invasive and metastasizing tumours which may cause virilism or Cushing's syndrome. (05 Mar 2000) |
| adrenal cortical syndrome | <syndrome> An inexact (and obsolete) term that has been applied to Cushing's syndrome, Addison's disease, or the adrenogenital syndrome. (05 Mar 2000) |
| blindness, cortical | Total loss of vision in all or part of the visual field due to a lesion in the striate area, characterised by the patient's subjective unawareness of his disability and the absence of cortical functions of vision, with the subcortical functions intact. (12 Dec 1998) |
| carcinoma, adrenal cortical | A malignant neoplasm of adrenal cortical cells demonstrating partial or complete histological and functional differentiation. They are rare, comprising between only 0.05% and 0.2% of all cancers. Women develop functional adrenal cortical carcinomas more commonly than men, but men develop nonfunctioning ones more often than women. Hypercortisolism is the most common presentation for this cancer. Virilism and cushing's syndrome may also result. (12 Dec 1998) |
| generalised cortical hyperostosis | <syndrome> An inherited skeletal dysplasia, with mandibular enlargement and thickening of the diaphyses and calvaria, and increased serum alkaline phosphatase; autosomal recessive inheritance. Synonym: generalised cortical hyperostosis. (05 Mar 2000) |
| renal cortical adenoma | <tumour> One of the usually small adenoma's sometimes found in the renal cortex and derived from renal tubular tissue. (05 Mar 2000) |
