This was tested in people. That is the most reliable kind of research we share.
This is a report on one child, not a test of any treatment.
The short version
Doctors first thought a 4-year-old girl had a brain infection, but she had a rare tumor.
What was studied. This is a report about one child, a 4-year-old girl. It tells how doctors found out she had a rare tumor called DLGNT.
What they found. At first she had constipation and was not growing well. Later, in the hospital, she showed signs of nerve problems. Doctors thought she might have TB meningitis, an infection of the lining around the brain. Her spinal fluid test did not grow any germs. She was likely started on TB medicine and a steroid anyway. A brain scan showed spots along the lining of the brain. A close look at tissue under a microscope confirmed the tumor. It also found a gene change called BRAF: A gene in a pathway that tells cells to divide. Some tumors carry a change in it. There are drugs made to target that change, so your team may test for it. See the glossary.
What this means, and what it doesn't
What it could mean: This tumor is rare and can look like an infection in the lining of the brain. Many doctors may not know much about it yet. The authors say gene testing is key to finding it.
What it doesn't mean: This is the story of just one child. It did not test any treatment. It does not mean that every brain infection is really a tumor. It is not a cure or a new way to treat this tumor.
