What Do Lesions On The Brain Mean
Nonspecific: Scattered white spots confined to the white matter of the brain are fairly common and not specific for a certain disease. White spots in a person less than 50 yrs. Old, however, are usually abnormal and may be seen with multiple sclerosis among many other entities. As one ages, these are more likely due to tiny arterial blockages and are fairly common in people over 70 yrs. Old. ...Read moreSee 1 more doctor answer
It depends....: How white, grey or black signal on an MRI scan is interpreted depends on the type of sequence that spot appears in. So without knowing the sequence, i can only guess. If these are scattered black dots they could represent small foci of old hemorrhage or iron deposition. If it is a bigger spot it could represent a fluid collection. I really would have to see the images to give you an answer. ...Read more
Variety: "Spots" usually describes white matter lesions, which may be due to aging, prior head injury, smoking, high blood pressure, hardening of arteries, migraine, even multiple sclerosis. In other words, does it correlate with your symptoms prompting the study. Ask the doctor who ordered the study. ...Read more
See below: The brain is composed of white and gray matters. Gray matter is where the higher brain functions take place and the white matter usually transmits those functions. I believe you're refering to white matter changes seen on MRI or ct. These are nonspecific & may be seen with chronic small vessel changes from diabetes or hypertension or from multiple sclerosis or other problems. ...Read more
Cysts: It is not uncommon to see lesions in various structures on an MRI of the lumbar spine, most commonly the kidneys and ovaries; they usually represent simple cysts. Because the MRI lumbar is not the test of choice to evauate the ovaries, it is usually recommended that a more appropriate followup test be done such as an ultrasound of the ovaries and followup with a gynecologist. ...Read more
Many possibilities: Bumps under the skin could be as a result of different reasons of which could include an ingrown hair, acne, infection, abscess, or an allergic reaction to various things like detergents or soaps or to medications. Have it evaluated by your physician to get the appropriate treatment. ...Read more
Need more info: "spots" can mean a lot of things. Most commonly, there are small areas of increased signal on t2 or flair MRI sequences which generally represent small "scars" or gliosis. It is not unusual to have 1 of these areas for every 10 years of age, so a 50 year old person could have 5-6 and be considered normal. However, the spots you mean could be something completely different. Ask your doctor. ...Read more
Benign: Hemangiomas are a common finding in the vertebrae and are benign. They are collections of blood vessels with a very specific appearance on mri. It is only when they are very large and expand the vertebrae or weaken it that they can be a problem. This is very rare. ...Read moreSee 1 more doctor answer
Looking for what?: It depends on what is being looked for. Pet/ct looks at the metabolism. Or the function of the area scanned (brain in this case), using different radioactive drugs, or tracers. The most common is f-18 fdg, an analog of glucose, which images glucose consumption. Other radiotracers look at protein synthesis or for evidence of the plaques that are associated with alzheimer's. ...Read moreSee 4 more doctor answers
?????: Do you mean outside the skull or inside the skull? Is this something you can feel on the side of your head? Because you said "frontal lobe," but the frontal lobe is on the other side of some tough bone. If you mean actually in the brain, you'll have to explain "soft spot," because the living brain has roughly the consistency of raw egg yolk. It's ALL soft. Please repost with clearer wording. ...Read more
What does it mean when the Grey matter in the brain is leaking into the white matter of the brain? And what kind of effects can it have?
Which planet we on?: Here on Earth there are no human beings who leak Grey matter into white matter. Do you have a report of some sort that you're looking at & trying to interpret? The only thing I can think of that would have any remote significance to what you're saying is called "heterotopia" which refers to islands of gray matter within white matter territory. Seizures are known to occur as a main manifestation. ...Read more
What does attenuated ACL on a MRI? What does intra substance signal menisci mean on MRI? Please help me understand in English what these two mean?
Need whole: Doctors will need to see the whole report & probably the pictures to help interpret the MRI for you. Consider using HealthTap Prime to relay your question. Alternatively talk to the doctor who ordered the MRI (not the Radiologist who issued the report) to put it in context. ACL is the anterior cruciate ligament (holds the knee from slipping off backwards). Attenuated means less bright/lower signal ...Read more
