Brain biopsy

Brain biopsy is a medical procedure that involves the removal of a small sample of brain tissue for examination under a microscope. This procedure is typically performed to diagnose a variety of brain conditions, including brain tumors, inflammation, infection, and other neurological disorders.

Procedure

A brain biopsy can be performed in several ways. The most common method is a stereotactic biopsy, which uses a computer and a three-dimensional scanning device to locate the exact area of the brain from which the tissue sample will be taken. Other methods include an open biopsy, where a portion of the skull is removed to access the brain, and a needle biopsy, where a long, thin needle is inserted through a small hole drilled in the skull.

Indications

A brain biopsy may be recommended when imaging studies such as MRI or CT scan show an abnormality in the brain that cannot be diagnosed by non-invasive methods. Conditions that may require a brain biopsy for diagnosis include brain tumors, neurological disorders, infections, and inflammatory diseases of the brain.

Risks

As with any surgical procedure, a brain biopsy carries some risks. These may include infection, bleeding, and damage to the surrounding brain tissue. There is also a small risk of complications from the anesthesia used during the procedure.

Recovery

Recovery from a brain biopsy will depend on the individual patient and the specific procedure used. Most patients are able to return home the same day or the day after the procedure, but some may require a longer hospital stay.
