Brain biopsy

Brain biopsy is the removal of a small piece of brain tissue for the diagnosis of abnormalities of the brain. It is used to diagnose tumors, infection, inflammation, and other brain disorders. By examining the tissue sample under a microscope, the biopsy sample provides information about the appropriate diagnosis and treatment. Brain biopsy is the removal of a small piece of brain tissue for the diagnosis of abnormalities of the brain. It is used to diagnose tumors, infection, inflammation, and other brain disorders. By examining the tissue sample under a microscope, the biopsy sample provides information about the appropriate diagnosis and treatment. Given the potential risks surrounding the procedure, cerebral biopsy is indicated only if other diagnostic approaches (e.g. magnetic resonance imaging) have been insufficient in showing the cause of symptoms, and if it is felt that the benefits of histological diagnosis will influence the treatment plan. If the person has a brain tumor, biopsy is 95% sensitive. The procedure can also be valuable in people who are immunocompromised and who have evidence of brain lesions that could be caused by opportunistic infections. In other groups, particularly those with unexplained neurological disease, a diagnosis is reached by performing a biopsy in half the cases where it is done, and it has helpful practical effect in 30% of people. If primary angiitis of the central nervous system (PACNS) is suspected, brain biopsy is most likely to positively influence the treatment plan. Procedures are categorized into stereotactic, needle, and open. Stereotactic is the least invasive and open is the most invasive.
