- Review
- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This was used with one patient, so we do not yet know if it helps others.
The short version
Doctors printed a clear model of one woman's brain to help plan a safer path to her tumor.
What was studied. This is a report about one patient, a woman aged 40. She had a large 7-cm tumor deep inside the left side of her brain.
What they found. The team printed a clear model of her brain that also showed nearby nerve paths. Surgeons filled out a survey and said the model helped them see the tumor and pick a route. They used a small opening to reach it, and scans after surgery showed the tumor was gone. Lab tests showed a Grade 2 atypical meningioma.
What this means, and what it doesn't
What it could mean: Models like this may help surgeons plan a safer route to a tumor deep in the brain. If you face brain surgery, you can ask your team how they plan their path.
What it doesn't mean: This is one person's case, not a study of many people. The model did not treat the tumor. It only helped with planning. The authors say more study is needed to know if it changes how patients do. It is not a treatment and it is not a cure. Most hospitals do not do this today.
