Kidney showing circumscribed calcium deposits together with a partial stag horn calculus. Nephrocalcinosis , once known as Albright's calcinosis after Fuller Albright , is a term originally used to describe the deposition of poorly soluble calcium salts in the renal parenchyma due to hyperparathyroidism .
Calciphylaxis, also known as calcific uremic arteriolopathy (CUA) or “Grey Scale”, is a rare syndrome characterized by painful skin lesions.The pathogenesis of calciphylaxis is unclear but believed to involve calcification of the small blood vessels located within the fatty tissue and deeper layers of the skin, blood clots, and eventual death of skin cells due to lack of blood flow.

Primary familial brain calcification [1] (PFBC), also known as familial idiopathic basal ganglia calcification (FIBGC) and Fahr's disease, [1] is a rare, [2] genetically dominant or recessive, inherited neurological disorder characterized by abnormal deposits of calcium in areas of the brain that control movement.
In dystrophic calcification, basophilic calcium salt deposits aggregate, first in the mitochondria, then progressively throughout the cell. [citation needed] These calcifications are an indication of previous microscopic cell injury, occurring in areas of cell necrosis when activated phosphatases bind calcium ions to phospholipids in the membrane.
Calcinosis is the formation of calcium deposits in any soft tissue. [1] It is a rare condition that has many different causes. These range from infection and injury to systemic diseases like kidney failure .
Calcification of soft tissue (arteries, cartilage, heart valves, [1] [2] etc.) can be caused by vitamin K 2 deficiency or by poor calcium absorption due to a high calcium/vitamin D ratio. This can occur with or without a mineral imbalance. A common misconception is that calcification is caused by excess amount of calcium in diet. Dietary ...
Metastatic calcinosis cutis is the consequence of calcium salts precipitating in normal tissue due to an underlying abnormality in the metabolism of phosphate and/or calcium. [2] Metastatic calcification can result from any systemic condition raising serum calcium and/or phosphate levels. Chronic renal failure is the most frequent underlying ...
Intracranial tuberculomas in children are often infratentorial, occurring near the cerebellum and base of the brain. In this population, symptoms such as headache, fever, focal neurologic findings and seizures have been seen [ 3 ] in addition to papilledema with or without meningitis . [ 20 ]
