- Tested in people
This was tested in people. That is the most reliable kind of research we share.
Doctors tried this in one person and wrote up what happened.
The short version
Doctors drained a fluid filled tumor sac through the nose, guided by live MRI pictures.
What was studied. This is a report on one patient. She was a 77 year old woman with a craniopharyngioma, a rare brain tumor that is not cancer. The tumor had been removed before through her nose. Later a new fluid filled sac showed up in the same area.
What they found. The team passed a thin drainage tube through her nose into the sac. Live MRI scans during surgery showed where the tube was going. The scans also confirmed the sac got smaller as the fluid came out. The fluid was then checked in the lab.
What this means, and what it doesn't
What it could mean: For some people, a returning cyst might be drained without a bigger operation. That could matter when a repeat surgery would be too risky. The doctors suggest this may be a first step in carefully chosen patients.
What it doesn't mean: This is one case report, not a study of many people. It does not tell us how often the sac comes back, or how long the relief lasts. One good result in one person does not prove the method works for everyone. This is not a cure for the tumor, and it is not a new standard of care. Ask your own care team what fits your situation.
