A brain biopsy is a procedure that involves taking a small sample of brain tissue to diagnose conditions like brain cancer, infections, or inflammation. It is performed under general anesthesia, using a needle inserted through a hole in the skull. Risks include damage to the brain and infection, but the procedure is generally safe. Recovery involves mild to moderate pain and a few days in the hospital. Results take a few days.
A brain biopsy involves taking a sample of brain tissue to help diagnose certain conditions, such as brain cancer. It can also help determine if there is an infection or inflammation in the brain. The tissue sample taken from the brain is usually small. A brain biopsy may also be performed during an autopsy to investigate certain medical conditions and brain abnormalities.
The procedure is usually performed under general anesthesia. Before the biopsy, a CT scan is done to pinpoint the specific area of the brain from which the sample will be taken. A needle is used to obtain the tissue sample. The needle is inserted into the brain through a hole made in the skull. With the help of a computerized imaging system, the surgeon is able to find the spot where the sample needs to be taken.
Depending on an individual’s symptoms, a biopsy may be needed to confirm a diagnosis. After the sample has been taken, a pathologist views the sample under a microscope. The pathologist identifies the type of cells present and can determine if there is abnormal cell growth. This helps determine whether a tumor found in the brain is cancerous or benign. If an infection is found, the type of organism responsible can be identified and appropriate treatment initiated.
Although a brain biopsy is invasive, it is considered safe. However there are always risks associated with any type of surgery, especially one involving the brain. The procedure is done under general anesthesia and some people may have a bad reaction to the medications used. There is also a small risk of infection.
When the needle is inserted into the brain, it is possible that an area of the brain could be damaged, which can cause a variety of problems, such as vision and speech problems. After a tissue sample is taken, a small amount of scar tissue may develop on the brain. Scar tissue can sometimes cause problems, such as seizures.
The brain biopsy usually takes a few hours and a patient will be monitored in the recovery room until the anesthesia wears off. Because the patient is asleep for the procedure, there isn’t much pain involved. During recovery, a patient may have mild to moderate pain in the area where the needle entered the skull. Most people do not experience serious complications, however patients do spend a few days in the hospital following the procedure. The results of a brain biopsy usually take a few days.
