A bursa is a thin fluid-filled sac that reduces friction forces between tissues of the body. Chronic (repeated of long-standing) inflammation of the bursa (bursitis) can lead to calcification of the bursa. This is referred to as “calcific bursitis.” The calcium deposition (calcification) can occur as long as the inflammation is present.
- Calcification, nonarteriosclerotic cerebral
Calcification, nonarteriosclerotic cerebral: This condition described in 1930 by T. Fahr (and therefore called Fahr syndrome) is a genetic (inherited) neurological disorder characterized by abnormal deposits of calcium in certain of areas of the brain (including the basal ganglia and the cerebral cortex). Symptoms may include motor function deterioration, dementia, mental retardation, spastic paralysis, dysarthria […]
Calcinosis: An abnormal deposit of calcium salts in body tissues. Examples include the calcifications in the skin from scleroderma and in the muscle from polymyositis.
- Calcified granuloma
Calcified granuloma: A node-like type of tissue inflammation that has a specific appearance under a microscope (granuloma) and contains calcium deposits. Because it usually takes some time for calcium to be deposited in a granuloma, it is generally assumed that a calcified granuloma is an old granuloma, or an old area of inflammation. For example, […]
Calcipotriene: A synthetic form of vitamin D3 that can be applied to the skin to treat psoriasis.
Calcitonin: A hormone produced by the thyroid gland that lowers the levels of calcium and phosphate in the blood and promotes the formation of bone. Bone is in a constant state of remodeling. Old bone is removed by cells called osteoclasts, and new bone is added by cells called osteoblasts. Calcitonin inhibits bone removal by […]
