Will A Brain Tumor That Causes Symptoms Show On An Mri
Not necessarily.: Bacterial meningitis is a devastating disease that must be caught early to prevent permanent damage or even death. In the beginning stages the only way to make the diagnosis is with a lumbar puncture commonly called a spinal tap. Neuro imaging studies are useful to monitor for complications such as abscesses and brain swelling and can pick up meningitis later in the disease process. ...Read moreSee 1 more doctor answer
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
Sometimes, yes: MRI brain is done in HA mostly to rule out serious problems like tumor, inflammation, infections, abscess causing HA, which is non-responsive to meds, worsening day by day and increase in severity. If you just have plain daily HA, which has been contrast then chances of MRI will show anything is pretty low. I would recommend virtual consult or concierge with me to discuss further. ...Read more
Would a Brain MRI without Contrast & a CT Scan with and without Contrast show a brain tumor causing symptoms? Worried that it could have been missed.
No symptomatic tumor: It is a pretty safe bet that MRI together with contrast CT can exclude a symptomatic tumor (mass) in the head. That does not mean all causes of headache or neurologic complaint are seen. Only your practitioner can give more advice to "put your mind at ease" and further direct your diagnostic journey. ...Read more
If a brain tumor is causing forehead pressure tightness and dizziness, would it show on CT scan without contrast? Like brain shift or some evidence?
Well...: Tumors larger than 6 mm will show on a CT scan with contrast. But at that size it would be highly unlikely to have any of these symptoms. An MRI is way better to visualize brain pathology. Yet at this point I doubt you have a large enough brain tumor that would cause these symptoms... Do not panic, sounds more like a sinus problem ...Read more
Can an EEG detect any/every brain tumor? Meaning if someone has a brain tumor will it for sure be detectable on an EEG?
OneThingForSure:----: My dear 19-year-old: NOTHING in life is"for sure."And the way things are going so fast, probably NOT even death, but"for sure"higher taxes and regulations.But the EEG is pretty good at following physiologic changes and potential for seizures.It depends on the location, size and depth of the tumor plus what specific structures are involved.And, it's usually not used to detect a tumor. For that: MRI ...Read more
Would an MRI withOUT contrast on the brain and neck reveal if lymph nodes in neck are cancerous? Also, would it reveal common brain abnormalities?
MRI brain & neck: Without IV contrast would reveal common brain lesions, and depends on what's the ordering physician is looking for. As for the lymph nodes it would show better resolution than other modalities such as CT, but definitive diagnosis necessitates tissue diagnosis, either a biopsy or fine needle aspiration, good luck ...Read more
Depends on size,loc: MRI's limited resolution in "standard" view can miss tumors <1 cm in size. Dedicated MRI of the orbits (eyes) can see tumors that are ~0.2 cm in size, but require a special order to perform. Also, the tumors show up in a way that can be confused with normal vitreous fluid in the eye, so often dye is needed, depending on location. Talk to an ophthalmologist about symptoms 2 c if MRI order's correct ...Read more
Besides a brain tumur, bleed and stroke what else can show up on a MRI that causes severe headaches?
other things: Here are a few others i can think of--hydrocephalus, brain infections, vascular malformations, congenital malformations (chiari, etc.), sinus problems, spinal fluid leak, fractures, sinus thrombosis, certain demyelinating processes, vasculitis, certain toxicities. Hope that helps. ...Read moreSee 1 more doctor answer
Are persistent tingling in arms and legs for a few weeks an abnormal neurological finding? Does it warrant a MRI scan of the brain? Brain tumour?
Yes : Numbness and tingling of arms and feet requires medical evaluation . You need to see your primary care physician to some blood work first to rule out any metabolic reason for your symptoms . These will include test for thyroid disease , vitamin B12 deficiency , a metabolic panel and bold count . If all is negative , then a Neuro evaluation maybe needed . I doubt that you will need an MRI , ...Read moreSee 1 more doctor answer
It depends: Sometimes the tumors are so subtle that you cannot be certain. Many of the time the tumors will light up with contrast in which case you can be much more certain that it is tumor. But sometimes it is simply hard to tell and only biopsy will tell you if you have tumor which should be done only as a last resort because biopsying the spinal cord is fraught with danger. ...Read more
Does a head MRI both with and without contrast show if there is a problem or tumor in the pituitary gland?
What does a MRI of the pituitary gland check for? What kinds of abnormalities does it detect? Mri is without and then with contrast
Pituitary anatomy: Greetings, a pituitary MRI +\- contrast is done to evaluate the potential causes of pituitary hormone abnormalities. Typically, this would be looking for a pituitary adenoma, a benign tumor that can make excess hormones (eg-Prolactin) or damage the pituitary resulting in low hormone levels. Inflammation or a condition called an "empty sella" can also be seen and result in hormone problems. ...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
Maybe: L'hermitte-Duclos disease is a very condition that is not cancerous by itself. Since the majority involve the cerebellum, that is not a strong point for CT imaging because of the bones. They get in the way. Under certain conditions it may be visible. MRI is now a days the way to go. ...Read more
"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
