Although these tests are very good for detecting the presence of a mass in the brain, they are not good at identifying the exact nature of this mass (ie whether it is a tumour, inflammation or even bleeding within the brain). A sample of the fluid from around the brain may need to be taken to rule-out an inflammation of the brain and, in rare cases this can reveal the presence of a certain type of cancer called lymphoma. In order to confirm the exact cause of the mass and, if it is a cancer to find out how malignant it is, a tissue sample must be collected. This sample can be obtained by inserting a biopsy needle through the skull. If surgical removal of the mass is pl
