A brain tumor caused sudden bleeding around the brain, with no injury

Original title: A Case of Convexity Meningioma Presenting With Acute Subdural Hematoma: A Case Report With a Pooled Analysis of 63 Reported Cases.

How far along is this research?

This was tested in people. That is the most reliable kind of research we share.

This is a report of one real patient and a look back at past cases, not a test of a new treatment.

The short version

A man had bleeding around his brain with no fall or blow to the head, and a small tumor turned out to be the source.

What was studied. Doctors report one patient, a 65-year-old man who came in with a headache that kept getting worse and no history of injury. They also looked back at cases like his that had been reported before.

What they found. A CT scan showed fresh bleeding over the left side of his brain. An MRI showed a small growth right next to the bleed, and an angiogram found no tangled blood vessels. Surgeons removed the whole tumor and cleared out the blood. Lab tests showed the growth was a meningioma, a tumor of the layers covering the brain, with damaged veins inside it, bleeding inside it, and some dead tissue. He recovered after surgery with no nerve problems.

What this means, and what it doesn't

What it could mean: If someone has sudden bleeding around the brain and there was no injury, a meningioma can be one cause. Doctors may look for a tumor in that situation, not just assume it was trauma. Surgery to take out the tumor and clear the blood worked well for this man.

What it doesn't mean: This is one patient's story, plus a look back at earlier reports. It is not a trial, and it does not test a new drug or a new treatment. It is not a cure for anything. This kind of bleeding from a meningioma is very rare, so it is not something most people with a meningioma should expect. The authors say there is still no reliable way to tell ahead of time who will bleed. Care has to be decided one person at a time, based on the tumor, the person's symptoms, whether surgery is possible, and what the person wants.
