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.
