Calcified foci can occur in multiple organs, and commonly include pulmonary calcified foci, hepatic calcified foci, prostate calcified foci, and renal calcified foci. They are usually caused by inflammation or tuberculosis infection, and are formed by the deposition of calcium salts in local tissues. Calcified foci can be divided into microcalcified foci (≤1mm in diameter) and macrocalcified foci (>1mm in diameter) according to the size of the diameter, and according to the different parts of the occurrence of the foci can be divided into calcified foci of the lungs, hepatic foci, prostate foci, renal foci, splenic foci, breast foci, and so on. Calcified foci itself is a manifestation of disease regression, often formed by the absorption of inflammation after the disease is cured, generally no treatment is needed, and regular review is sufficient. If the primary disease is still not cured, treatment should be directed at the primary disease to prevent excessive calcification foci. If calcified foci appear with other symptoms, patients should go to the hospital in a timely manner to clarify the cause and provide targeted treatment.
