This was tested in people. That is the most reliable kind of research we share.
This is a report about one patient, not a new treatment.
The short version
Doctors found a rare tumor that grew outside the skull, not inside it.
What was studied. This is a report about one patient. A 53-year-old woman had a lump in her left temple that kept getting bigger. Doctors used scans, surgery, and lab tests to find out what it was.
What they found. Scans showed a tumor on a bone at the base of the skull. It reached into the eye socket area and the temple. The bone was thinned and reshaped, but not broken down. During surgery, doctors saw the tumor was not attached to the covering of the brain. Lab tests showed it was a grade 1 meningioma, the slowest growing kind.
What this means, and what it doesn't
What it could mean: Some meningiomas can start outside the skull. Doctors who know this may get the diagnosis right sooner. In this case, surgery removed the tumor.
What it doesn't mean: This is one person's story, not a study of many people. It does not test a new drug or a new treatment. It is not a cure, and it does not promise the same result for anyone else. It mostly reminds doctors to keep this rare tumor in mind.
