This was tested in people. That is the most reliable kind of research we share.
This is a report on one patient who had surgery, not a study that tests a treatment.
The short version
Doctors found a rare kind of tumor at the back of one woman's brain, and surgery took all of it out.
What was studied. This is a report about one patient. She was a woman in her 50s with a growing tremor on her right side. A brain scan showed a growth on the left, at the back of the brain, sitting on the covering of the brain rather than inside brain tissue.
What they found. At first, doctors thought the growth was a meningioma, a more common type. Surgeons removed the whole growth, and there were no complications. Tests on the tissue showed it was made of muscle-like cells wrapped around blood vessels, which gave it the name angioleiomyoma. At the 1-year check, she had no nerve problems and scans showed the tumor had not come back.
What this means, and what it doesn't
What it could mean: This type of growth is very rare, and it can look like other tumors on a scan. So a scan alone may not give the final answer. For growths in this part of the head, the report suggests that taking the whole growth out can work well. This one woman was doing well a year later.
What it doesn't mean: This is one person's story, not a study. It does not tell us how other people will do. It is not a new treatment, and it is not a promise of a cure. It also does not mean a growth in this area is likely to be this rare type. Most are not.
