The intracranial multiple calcification foci, just like bone or lung calcification foci, are caused by old lesions or physiological calcification, such as the pineal gland and the basal ganglia of the choroid plexus, which will form some calcification points during the growth and development process. However, these calcified spots usually do not cause any symptoms to the patients and the patients do not need to worry too much. However, some of the multiple calcifications in the brain are caused by diseases such as hereditary diseases, tumor diseases, congenital genetic metabolic diseases, hypoparathyroidism, vitamin D toxicity, etc. It is recommended to look for these causes.
