Hello @wayneesc and welcome to Mayo Connect. I appreciate the thoughtful questions you are asking about your mom's condition. As you said that your mom is quite frail, I'm assuming that she is elderly and most likely has other health issues. Is this the case?

If you would like to connect with other members who have discussed having a meningioma, here is a link where you will find several discussions about this. Feel free to post any questions in any of these discussions,

Have you considered having your mom evaluated by a physician who specializes in palliative care? Palliative care is not the same as hospice but does provide help for anyone who has a serious health condition. Here is some information about palliative care

Here is a quote from the above referenced article.
"Palliative care is provided by a team of health care providers, including doctors, nurses, social workers, chaplains and other trained specialists. The team works with you, your family and your other providers to add an extra layer of support and relief that complements your ongoing care."

Palliative care workers might be able to answer some of these questions that you have. Often, palliative care nurses will come to the home of someone who is homebound.

As you are comfortable doing so, could you share what type of symptoms led to your mom's diagnosis? How is she feeling now?
