This was tested in people. That is the most reliable kind of research we share.
This is one patient's case report, not a treatment tested in a study.
The short version
Doctors found a rare immune cell cancer in the brain that first looked like a much more common tumor.
What was studied. Doctors wrote up one patient. A 41 year old woman came in with a severe headache and then became suddenly confused.
What they found. Her scan showed a mass at the edge of the brain with heavy swelling that pushed her brain out of place. Surgeons removed it right away because of the pressure. Lab tests on the tissue showed a rare cancer of immune cells, not the common tumor it looked like on the scan.
What this means, and what it doesn't
What it could mean: A mass like this can be mistaken for a common tumor called a meningioma. Knowing that lymphoma is possible may help doctors reach the right answer sooner.
What it doesn't mean: This is one patient's story, not a study of a treatment. It does not test a new drug and it is not a cure. It cannot tell you what will happen to anyone else. Decisions about this rare cancer still rest with your own care team.
