How can MRI on brain miss a brain tumor when two eye docs, 2 neruo, and 2neruosurgeon all say can't see tumor but there could be one starting and now have one avm in oct last year and one this June.
MRI scans: To see a tumor or AVM with MRI depends on many factors, including the size, shape, location, enhancement and secondary signs such as edema and changes in normal anatomy. A very small tumor in the right location can be easily seen, but even larger tumors cannot be seen until they change the anatomy of the rest of the brain or enhance. And very small tumors at times are not seen. Same for AVM. ...Read moreSee 1 more doctor answer

Unlikely.: Always possible, but very low probability. Currently, MRI is the most sensitive imaging test of the head (particularly in the brain) in routine clinical practice. PET scans are another imaging modality that an oncologist can decide to perform if there is a high index of suspicion even after the negative MRI in some individualized cases. ...Read more

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

Why do neurosurgeon say no to fix two small angionomas with lesion and they won't do MRI to see if it is a brain tumor starting live in Utah.
Not every angioma needs an MRI or MRA to be evaluated. If there is a clear angioma on CT scan, and it is small, an MRI would probably not help. And in such a case, surgery could do more harm than good.
If the diagnosis is not certain, than an MRI or MRA can help determine what it is. Do you mean a cavernous hemangioma?
It should be removed only if it is deemed to be a risk. ...Read more
MRI showed brain lesion... What will they do next? And can it be something seriouse. If it was a brain tumor would they have known from this MRI
It depends: The MRI is very good, but not perfect in identifying what the lesion is. The treatment will depend on what the MRI shows. If it is not clear, either it will be followed with serial MRIs or it will be biopsied. If it is known, it will be either followed or treated depending on what it is. Occasionally, it will be surgically removed. ...Read moreSee 2 more doctor answers
Tumor type: This depends on tumor type, size and location. If the type of tumor is not clearly obvious on mri, biopsy or removal may be needed. If it is small and clearly benign, it may be feasible to follow it over time wit homer imaging. You'll need to talk to your doctor for more information. ...Read more
What to do if I just got diagnosed with a brain tumor. Is it possible to obtain a printout copy of my mri?
"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
