- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This is a report on one patient who had surgery, not a study that tested a new treatment.
The short version
A woman had a rare, non-cancerous tumor growing inside her skull bone, and surgery took it out.
What was studied. This is a report about one patient. A 50-year-old woman had a lump on the right side of her head that slowly grew over 5 years, along with mild headache.
What they found. Scans showed the tumor grew from 5.8 x 5.1 x 1.8 cm in 2019 to 17.6 x 14.3 x 4.4 cm in 2024. Surgeons removed the affected piece of skull bone. Tests showed the tumor was benign, which means it was not cancer. Her recovery went smoothly, she had no nerve problems, and 1 year later scans showed no sign of it coming back.
What this means, and what it doesn't
What it could mean: This kind of tumor starts in the skull bone itself. It is rare, making up less than 1% of all meningiomas. It can look alarming on scans and still turn out to be benign. Doctors may want to think about it when someone has a large lump on the skull.
What it doesn't mean: This is one person's story, not a study of many people. One case cannot show how well this surgery works for everyone. She was only followed for 1 year, so nothing is known here about the long run. It is not a promise of a cure, and it does not change treatment for other kinds of brain tumors.
