When the symptoms of brain lesions are detected, the physician prescribes imaging – magnetic resonance imaging, computer tomography, which visualizes neoplasms in the brain. If after the imaging examination, the specialist has doubts about the accuracy of the diagnosis, he may appoint a biopsy of the brain.


The essence of the biopsy is to extract from the brain a certain type of tissue, the study of which will allow a more accurate diagnosis of the disease. This diagnostic method is used with a histological purpose to determine the changes that brain tissue has experienced in some diseases.


There are 3 types of cerebral biopsy:

  • Drilling biopsy. A hole is pierced in the skull, through which a thin hollow needle is inserted, with which material is taken.
  • Stereotactic biopsy. This procedure is considered minimally invasive as minimal amount of brain tissue is removed. Control during the procedure is done by computer or nuclear magnetic resonance.
  • Open biopsy. It is associated with removing a specific bone of the skull. This is a complicated surgical intervention that is performed with complete anesthesia.
