Overview
Other Diagnostic Studies
- Biopsy of the brain may be helpful in the diagnostis of intracerebral metastases.[1]
- Brain biopsy of the brain is done to confirm the diagnosis of brain metastases, if the type of primary tumor is unknown or the etiology of the brain abnormality is unknown.
- Biopsy may be of two types: open and stereotactic.
- Indications for open biopsy and stereotactic biopsy are described below:[2]
