I would like to talk about the spots seen in the brain MRI (MRI), which are frequently asked questions of the neurologist.
What is the spot (lesion, ischemic gliotic focus) in the brain MRI?
The spot (lesion, ischemic gliotic focus) in the brain MRI ) are bright formations that are not normally seen in brain MRI. These are mostly benign, may be the result of capillary occlusion in the brain, or may be familial for no reason.
Why is a brain MRI performed?
See a brain neurologist for headaches, dizziness, fainting, numbness, blurred memory. When applied for any reason such as brain tumor, inflammatory diseases, vascular occlusion, shrinkage in the brain, brain vascular abnormalities and multiple sclerosis, brain MRI (cranial MRI) is requested due to suspicion of diseases such as.
What is the non-specific ischemic gliotic focus that is frequently encountered in MRI reports?
The non-specific ischemic gliotic focus we encounter in MRI reports may indicate that you have a possible small vessel occlusion that is not due to a specific cause. Findings called ischemic gliotic foci may occur as a result of small-diameter vessels being blocked or affected for various reasons. It is usually not progressive and may be a sign of some events that have already happened and are over. Gliotic focus can generally be considered as the blockage of capillaries in the brain as a result of damage to the nervous system or lack of oxygen.
What are the causes of spots on brain MRI?
The causes of spots on brain MRI may be congenital or may occur later. Frequently migraine, fatty diet, obesity, high blood pressure, diabetes, heart disease, neck vein occlusion, migraine, some familial coagulation disorders, diseases experienced in the womb and previous infections and head trauma may be the causes of this condition. The cause of many of these spots is idiopathic, that is, the cause cannot be determined and does not indicate a significant disease. If patients have a family history of vascular occlusion at a young age, it is likely to be genetic.
Are the spots seen in brain MRI dangerous?
Spots seen in brain MRI should be followed, depending on the follow-up results, whether they are dangerous or not. It is decided that it is not. When a single spot is detected in the brain MRI, a follow-up MRI usually needs to be performed 3-6 months later. . When a brain MRI is taken after 3-6 months, if the spot found in the MRI has not changed or grown, its number has not increased and it is not seen in the MRI with medication, it is not dangerous. If a stain appears on the MRI with medication or if there is medication retention, it suggests a diagnosis of vascular inflammation, brain tumor or multiple sclerosis. The size, number, location and shape of these spots become important in differential diagnosis.
When are the spots seen in brain MRI considered unimportant?
Brain MRI is generally performed in patients with headache. It is not important to have spots (ischemic gliotic foci) on brain MRI in someone who only has a headache. It only shows us that that person is prone to atherosclerosis. These spots are more common in the brain, especially in those with migraine-type headaches. If there are many spots on the brain, low dose aspirin is used as a precaution. Even if there are spots on a person's brain MRI, it does not matter if there is no speech disorder, no weakness or paralysis in the arm or leg on one side of the body, no vision loss, no imbalance, no confusion, no memory loss. If the person has no neurological findings and there is no abnormality in the examination, it is not important to have a spot on the MRI.
Why are the spots seen in the brain MRI followed?
When spots are detected in the brain MRI, these spots are 3 -Followed up with neurological examination and MRI every 6 months. Because if these spots are more than one, it may be the beginning of Multiple sclerosis (MS) disease or cerebrovascular inflammation. Additionally, if the spot is large, it is monitored as it may be the first sign of a brain tumor. These situations generally occur with a probability of less than 10%, but early detection is important for early treatment.
When are the spots seen on brain MRI diagnosed with MS? Does it benefit?
Brain MRI has characteristics of the spots seen in MS. At least one of the spots seen in MS must contain medication, or there must be at least 9 MS spots. Their shape is oval and they have special locations (such as periventricular, infratenorial, corpus callosum, cerebellum and spinal cord). MS is diagnosed with these spots, along with the patient's complaints and neurological examination.
When do the spots seen on brain MRI help in the diagnosis of brain tumor?
If a single spot on brain MRI grows on the follow-up MRI, there may be edema around it. If the stain is swollen, the stain is resistant to medication, and the patient's neurological complaints are increasing, a brain tumor is considered. If someone with cancer in another part of the body has neurological complaints such as headache, dizziness, numbness, speech disorder, memory confusion, weakness, a brain MRI is performed. If a spot or spots are detected in the brain MRI and these spots have retained medication, it is diagnosed that the cancer, called metastasis, has spread to the brain.
Is there a treatment for the spots seen in the brain MRI?
The small vessel called ischemic gliotic focus seen in the brain MRI is diagnosed. There is no treatment to eliminate or correct blockages. However, if these spots are more than one and the person has any disease that predisposes to vascular occlusion, low dose aspirin is used to prevent a new vascular occlusion.
