This is one patient's story, not a test of a new treatment.
The short version
A new mom's weak leg was not a back problem. It was a brain tumor.
What was studied. Doctors describe one 41-year-old woman who had just had a baby. She came in with low back pain and a painless weak left leg, after three falls.
What they found. Her exam showed the weak leg did not come from a nerve in her back. It pointed instead to her brain. A brain scan found a large growth called a meningioma. It pressed on both frontal lobe: The part of the brain above and behind your forehead. There are two, one on each side, and they are the largest of the brain's four lobes. See the glossary, more on the right. Surgeons removed it, and her weakness went away completely.
What this means, and what it doesn't
What it could mean: Back pain after birth is common, and it is almost never a brain tumor. But weakness with no pain can be a warning sign. A careful exam can show where the trouble really starts. In this woman's case, that exam led to the tumor being found and removed.
What it doesn't mean: This is one person's story, not a study. It does not mean leg weakness points to a brain tumor. Most back pain after having a baby has a simple cause. This is not a new treatment, and it is not a promise of a cure. It does not change how doctors treat brain tumors.
