- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at scans from past patients, so this is not a treatment yet.
The short version
An MRI sign may show which brain tumors are more likely to come back after surgery.
What was studied. Doctors looked back at 52 brain tumors called hemangioblastomas in 49 patients. The tumors were treated with surgery between 2010 and 2025. Doctors checked each MRI scan taken before surgery to see if the wall of the tumor's cyst lit up.
What they found. The main look was at 47 first surgeries. That included 44 tumors the surgeon was able to remove fully. Among those 44, the tumor came back in 8 of 14 tumors where the cyst wall lit up. It came back in none of the 30 tumors where the cyst wall did not light up.
What this means, and what it doesn't
What it could mean: This sign is easy to see on a scan a patient may already have. If it shows up, a doctor may want to watch more closely after surgery. It could help doctors plan follow-up scans.
What it doesn't mean: This does not mean the sign can tell any one person what will happen. It was an early study that looked back at old records, not a planned trial. It is not a treatment, and it is not a cure. The authors say the sign must be checked in larger groups of patients first.
