An x-ray showing calcific deposits in the area of the tendons of the rotator cuff muscles. Calcific tendinitis is typically diagnosed by physical examination and X-ray imaging. [1] During the formative phase, X-ray images typically reveal calcium deposits with uniform density and a clear margin. [1]
Calcinosis cutis is an uncommon condition marked by calcium buildup in the skin and subcutaneous tissues. Calcinosis cutis can range in intensity from little nodules in one area of the body to huge, crippling lesions affecting a vast portion of the body. [1]
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.
Idiopathic scrotal calcinosis is a cutaneous condition characterized by calcification of the skin resulting from the deposition of calcium and phosphorus occurring on the scrotum. [ 2 ] : 528 However, the levels of calcium and phosphate in the blood are normal. [ 3 ]
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.
Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue, [1] [2] causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [3]
The pallidal deposits stain positively for iron. Diffuse gliosis may surround the large deposits but significant loss of nerve cells is rare. On electron microscopy the mineral deposits appear as amorphous or crystalline material surrounded by a basal membrane. Calcium granules are seen within the cytoplasm of neuronal and glial cells.
Tumoral calcinosis is a rare condition in which there is calcium deposition in the soft tissue in periarticular location, around joints, outside the joint capsule. [1] They are frequently (0.5–3%) seen in patients undergoing renal dialysis.
