Understanding Chiari Malformation and Its Symptoms
Detecting Chiari Malformation with CT Scans Chiari Malformation is a condition at the base of the skull and cerebellum. It affects how the brain works. It happens when brain tissue moves into the spinal canal.
What is Chiari Malformation?
There are different types of Chiari Malformation, but Type I is most common in adults. It happens when the skull doesn’t fully form or shapes wrong. This puts pressure on the brain, pushing it down.
It’s important to find out if someone has Chiari Malformation early. A CT scan can help spot it. This makes treatment easier.
Common Symptoms of Chiari Malformation
Chiari Malformation can cause many symptoms. Some common ones are:
- Severe headaches, especially after coughing, sneezing, or straining
- Neck pain
- Unsteady gait and coordination issues
- Muscle weakness or numbness
- Dizziness and balance problems
- Difficulty swallowing
