Multiple cerebral cavernous foci is not the name of the disease, but rather a description of the results of imaging tests such as CT or MRI. It suggests that there are multiple small blood vessel obstructions in the brain, resulting in ischemic necrosis of part of the brain tissue, which in turn leads to the formation of cavernous foci, which are mostly seen in patients with cerebral infarction. Usually, multiple cerebral lacunar foci occur in the white matter part of the brain, mostly due to long-term hypertension, high blood pressure, high blood fat and other factors, caused by atherosclerosis in the brain, resulting in ischemic necrosis of brain tissues, necrotic brain cells will be phagocytosis, the formation of a cavity, cerebrospinal fluid will enter the cavity, when doing imaging tests can be seen in the multiple cerebral lacunar foci of the changes. If the patient is accompanied by headache, dizziness and other symptoms, it is recommended to consult a doctor in time for symptomatic treatment to avoid serious complications.
