What Causes Non Cancerous Tissue Mass On Left Side Of Brain?

Brief Answer:
You should obtain the pathology report

Detailed Answer:
Good evening. I am a neurologist and am glad that your mass lesion has been identified as at least not being cancerous. I can't really comment on your statement that nobody knows what the mass actually is after neurosurgery went in, drilled burr holes, and obviously sent a piece of tissue for pathology analysis.

I'm not aware of a situation where a good piece of biopsied tissue could not be identified pathologically. If you can obtain the pathology report and verify that the pathologist's diagnosis is actually, "UNKNOWN tissue sample" or something similar then, you may be able to request that a second opinion be rendered since tissue samples are saved and only small pieces blocked when analyzed. You should be able to get that sent to either another hospital or have another pathologist on staff take a look at the specimen.

The most common type of BENIGN tumor in the brain causing seizures are called meningiomas. These are easily detected both on MRI's as well as by biopsy.

If your lesion is a meningioma then, it is not likely to "disappear" over time and could possibly grow larger though they are typically slow to increase size. If it is scar tissue from some prior infection or trauma or other event then, that will not go away either but neither should it grow or change in any way.

I think the fact that your seizures have been so well controlled speaks to the highly benign nature of whatever this mass turns out to be.

Bottom line is if the neurosurgeon won't give you a satisfactory answer as to what the mass is...or at least what it is most likely to be then, I would get a copy of the pathology report.

I hope these suggestions and opinions satisfactorily address your question and give some additional information that you can discuss with the doctor for consideration. If so, may I ask your favor of a HIGH STAR RATING with some written feedback?

Also, if there are no other comments, may I ask you not forget to CLOSE THE QUERY on your end so the question can be transacted and archived for further reference by colleagues as necessary?
