Dystrophic calcification (DC) is the calcification occurring in degenerated or necrotic tissue, as in hyalinized scars, degenerated foci in leiomyomas, and caseous nodules. This occurs as a reaction to tissue damage, [ 1 ] including as a consequence of medical device implantation.
Ectopic calcification is a pathologic deposition of calcium salts in tissues or bone growth in soft tissues. This can be a symptom of hyperphosphatemia . Formation of osseous tissue in soft tissues such as the lungs, eyes, arteries, or other organs is known as ectopic calcification , dystrophic calcification , or ectopic ossification .
Calcific tendinitis is a common condition where deposits of calcium phosphate form in a tendon, sometimes causing pain at the affected site. Deposits can occur in several places in the body, but are by far most common in the rotator cuff of the shoulder.
Dystrophic calcinosis cutis is the most prevalent kind of calcification on the skin. [2] The ectopic calcified mass usually consists of amorphous calcium phosphate and hydroxyapatite. [6] Dystrophic calcification is linked to a number of illnesses, such as infections, hereditary diseases, cutaneous neoplasms, and connective tissue diseases. [7]
Similar calcification and ossification may be seen at peripheral entheseal sites, including the shoulder, iliac crest, ischial tuberosity, trochanters of the hip, tibial tuberosities, patellae, and bones of the hands and/or feet. [6] DISH can be a complicating factor when suffering from trauma involving the spine.
Enthesopathy can occur at the shoulder, elbow, wrist, carpus, hip, knee, ankle, tarsus, or heel bone, among other regions. Enthesopathies may take the form of spondyloarthropathies (joint diseases of the spine) such as ankylosing spondylitis, or psoriatic arthritis, plantar fasciitis, and Achilles tendinitis.
One of the principal causes of arterial stiffening with age is vascular calcification. Vascular calcification is the deposition of mineral in the form of calcium phosphate salts in the smooth muscle-rich medial layer of large arteries including the aorta. DNA damage, especially oxidative DNA damage, causes accelerated vascular calcification. [11]
Calcification is typically depicted 2 weeks earlier by ultrasound (US) when compared to radiographs. [6] The lesion develops in two distinct stages with different presentations at US. [ 7 ] In the early stage, termed immature, it depicts a non-specific soft tissue mass that ranges from a hypoechoic area with an outer sheet-like hyperechoic ...
