This was tested in people. That is the most reliable kind of research we share.
This is a report about one patient, not a tested treatment.
The short version
A woman's brain growths looked like a common tumor, but tests after surgery showed they were something different.
What was studied. This is a report about one patient. She was a 55-year-old woman who came in with a dull headache.
What they found. An MRI scan showed three growths near the back and top of her brain. Doctors thought they were meningiomas and watched them. After six years the growths had grown a little, and she asked for treatment, so they were removed by surgery. Tests on the removed tissue showed they were not meningiomas. They were dural cavernous hemangiomas, which are growths made of blood vessels. Before surgery, a scan of her blood vessels did not find any vessels feeding the growths.
What this means, and what it doesn't
What it could mean: Growths in this part of the brain are not always what the first scans suggest. The doctors here suggest that when a meningioma is the main suspected diagnosis in this area, a scan of the blood vessels should be part of the check before surgery. That could help doctors know what they are dealing with. If you have a growth like this, you can ask your care team what scans they plan to do before surgery.
What it doesn't mean: This is a report about one person, not a study of many people. It does not test a new treatment, and it is not a cure or a promise of one. One case cannot tell us how often this happens or what is best for everyone. It does not mean your diagnosis is wrong. Talk with your own doctors about your scans and your plan.
