- Review
- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This describes what happened to one patient, not a tested new treatment.
The short version
One man's brain scan looked like a tumor, but it turned out to be a TB infection.
What was studied. This report is about one 55-year-old man. For 4 weeks he had dizziness, trouble walking, and numbness on the left side of his face. He lived in an area where TB is common.
What they found. A brain scan showed a growth in his brainstem that looked like a tumor called a 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. He took TB drugs for 4 weeks, but he did not get better. Doctors then took out the growth with surgery. Lab tests showed it was a TB infection, not a tumor. He recovered well and took TB drugs for 12 months after surgery.
What this means, and what it doesn't
What it could mean: Sometimes a spot that looks like a brain tumor on a scan is really an infection. In places where TB is common, doctors may want to test for TB early. Surgery helped this man when the growth was pressing on his brain.
What it doesn't mean: This is the story of just one person. It does not mean that most brainstem growths are TB. A TB growth like this in the brainstem is very rare, and even more rare in adults. It does not change how brain tumors are treated. It is not a cure for brain tumors.
