Disseminated foci of calcification is a technical term used in imaging to describe pathological changes, mainly tissue damage caused by various factors, which appear as strong echoes or hyperdense shadows in the image. Diseases that can have scattered calcified foci on imaging include lung disease, breast disease, prostate disease, liver disease, and thyroid disease. Tuberculosis-induced infections can cause inflammation and calcification in lung tissue, which is the most common disease with scattered calcified foci on imaging, and inflammatory damage caused by infections from other diseases in the lungs can also show calcified foci. Breast cancer, mastitis and other factors cause breast tissue damage, imaging can also have calcified foci. In addition, prostatitis, thyroid tumors, liver tumors or hepatitis can also have scattered calcified foci.
