This was tested in people. That is the most reliable kind of research we share.
This is one patient's case report, not a new treatment a person can get.
The short version
Doctors found a fast growing brain tumor that scans first made look like something else.
What was studied. Doctors wrote up one patient, a 46 year old woman. She had 7 months of worsening thinking, slurred speech, and stiff, weak legs.
What they found. Her MRI showed changes on both sides of the brain in a very even pattern. That even pattern usually points to a white matter disease, not cancer. A stereotactic biopsy: Taking a small sample through a narrow opening in the skull, guided by a scan, instead of a full opening. It is used when a tumor is hard or risky to reach. See the glossary showed a fast growing brain tumor called a high grade glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary. Tests showed the tumor did not have a gene change called IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary.
What this means, and what it doesn't
What it could mean: Brain scans alone can fool doctors. Even, matching changes on both sides do not rule out cancer. Extra MRI tests and a biopsy may be needed to know what is really there.
What it doesn't mean: This is one person's story, written up by her doctors. It is not a study of a new treatment, and it is not a promise of a cure. It also does not mean most people with these scan findings have a tumor. It changes nothing about care today except to remind doctors to keep looking.
