| calcification | <biochemistry> The process by which organic tissue becomes hardened by a deposit of calcium salts within its substance. Origin: L. Facere = to make. (21 Mar 1998) |
|---|---|
| calcification lines of Retzius | Incremental line's of rhythmic deposition of successive layers of enamel matrix during development. Synonym: lines of Retzius. (05 Mar 2000) |
| calcification, physiologic | Process by which organic tissue becomes hardened by the physiologic deposit of calcium salts. (12 Dec 1998) |
| pathologic calcification | Calcification occurring in excretory or secretory passages as calculi, and in tissues other than bone and teeth. (05 Mar 2000) |
| renal calcification | <radiology> Nephrolithiasis, nephrocalcinosis, medullary (more common), cortical, neoplastic or inflammatory mass, renal cell carcinoma, XGP, tuberculosis (12 Dec 1998) |
| metastatic calcification | Calcification occurring in nonosseous, viable tissue (i.e., tissue that is not degenerated or necrotic), as in the stomach, lungs, and kidneys (and rarely in other sites); the cells of these organs secrete acid materials, and, under certain conditions in instances of hypercalcaemia, the alteration in pH seems to cause precipitation of calcium salts in these sites. (05 Mar 2000) |
| gyral brain calcification | <radiology> Sturge-Weber-Dimitri syndrome, treated CNS lymphoma, post-meningoencephalitis, brain tumour (oligodendroglioma) (12 Dec 1998) |
| physiological intracranial calcification | <radiology> Pineal gland, habenular commisure, choroid plexus, dura, pacchionian bodies, basal ganglia and dentate nucleus (12 Dec 1998) |
| Monckeberg's calcification | Arterial sclerosis involving the peripheral arteries, especially of the legs of older people, with deposition of calcium in the medial coat (pipestem arteries) but with little or no encroachment on the lumen. Synonym: medial arteriosclerosis, Monckeberg's calcification, Monckeberg's degeneration, Monckeberg's medial calcification, Monckeberg's sclerosis. (05 Mar 2000) |
| Monckeberg's medial calcification | Arterial sclerosis involving the peripheral arteries, especially of the legs of older people, with deposition of calcium in the medial coat (pipestem arteries) but with little or no encroachment on the lumen. Synonym: medial arteriosclerosis, Monckeberg's calcification, Monckeberg's degeneration, Monckeberg's medial calcification, Monckeberg's sclerosis. (05 Mar 2000) |
| pineal gland calcification | <radiology> Visible on plain skull film (33-76% in adults), seen more frequently on CT, rare in kids less than 6 y.o. (presence suggests neoplasm), usually in the form of a cluster of amorphous, irregular densities, may be solitary, the size of calcification: usually 3-5 mm, if greater than 1 cm, suspect pinealoma, AV malformation, etc. See: physiological intracranial calcifications (12 Dec 1998) |
| coronary artery calcification | <radiology> In setting of chest pain, upto 94% will have significant coronary artery calcification (12 Dec 1998) |
| pulp calcification | A calcified body found in the pulp chamber of a tooth; may be composed of irregular dentin (true denticle) or due to ectopic calcification of pulp tissue (false denticle). Synonym: denticle, pulp calcification, pulp calculus, pulp nodule, pulp stone. Origin: endo-+ G. Lithos, stone (05 Mar 2000) |
| spheroid calcification | <radiology> Round/oval subcutaneous calcifications, characteristic of Ehlers-Danlos syndrome (12 Dec 1998) |
| diffuse abdominal calcification | <radiology> Ovarian cystadenocarcinoma (psammomatous Calcium), pseudomyxoma peritonei, pseudomucinous cystadenoma of ovary, mucocele of appendix, undifferentiated abdominal malignancy, TB peritonitis, oil granulomata, meconium peritonitis (12 Dec 1998) |
