This was tested in people. That is the most reliable kind of research we share.
This is a report about one patient, not a study of a new treatment.
The short version
Doctors found a rare, non-cancerous tumor growing inside a woman's skull bone.
What was studied. This is a report about one patient. A 43 year old woman had on and off head pain for six months. Doctors used scans to study a spot in her skull bone.
What they found. Scans showed a hole in the bone on the right side of her forehead. It measured 1.9 x 0.9 cm. The scans had a clue called T2 shine through. That clue pointed to a fluid filled tumor, not a fast growing bone cancer. Surgeons took out the whole tumor and rebuilt the bone with a titanium mesh. Tissue tests showed a CNS WHO grade: A number from 1 to 4 for how a tumor is likely to behave. Since 2021 it is written in plain numbers, not Roman ones. Gene results can set it too. See the glossary I microcystic meningioma, a slow growing and benign tumor.
What this means, and what it doesn't
What it could mean: A single spot of bone loss in the skull can have many causes. This kind of tumor is one of them. Knowing that may help doctors read the scan better. It may also help them plan the right surgery.
What it doesn't mean: This is one patient's story, not a study. It does not test a new drug or a new treatment. It is not a cure and it is not a promise for anyone else. Your own scan may mean something very different. Only your care team can tell you what your scan shows.
