Intracerebral calcification, sometimes known as intercranial calcification, is a condition in which calcium and iron deposits are found within the brain. These calcium deposits are sometimes an indicator of disease and sometimes part of the aging process.
Age
As the body ages, calcification within the brain can occur. The most common site for calcification is in the choroid plexus, the area of the brain that is found within the ventricles and produces cerebrospinal fluid.
Tumors
Calcification often occurs with brain tumors such as gliomas. A slow growing tumor is more likely to produce calcification than an aggressive, fast growing tumor.
Vascular Conditions
There are several vascular conditions that may lead to intracerebral calcification, including aneurysms, angiomas and hematomas.
Infections
Certain types of infections can produce calcification within the brain. These include tuberculous meningitis and cytomegalovirus. According to the Centers for Disease Control and Prevention, cytomegalovirus is a type of herpes virus found in 50 percent to 80 percent of adults in the United States.
Rare Causes
Several rare causes of intracerebral calcification include Fahr's syndrome, Cockayne's syndrome, lead poisoning and carbon monoxide poisoning. Calcification might occur with hyperparathyroidism but is extremely rare.
