Chapter 78

Once a sample is obtained, a pathologist examines the tissue under a microscope and writes a pathology report containing an analysis of the brain tissue. Sometimes the pathologist may not be able to make an exact diagnosis. This may be because more than one grade of tumor cells exists within the same tumor. In some cases, the tissue may be sent to another institution for additional analysis.

A pathology report contains the analysis of brain tissue taken at the time of a craniotomy or needle biopsy. A pathologist examines the tissue under a microscope. Further tests or analysis may be performed on the tumor tissue. Then the pathologist will write a pathology report, which provides the information to make a diagnosis of the tumor type.

Sometimes the pathologist may not be able to make an exact diagnosis. This may be because more than one grade of tumor cells exists within the same tumor. If cells of only one grade are removed and classified during a biopsy, it is possible that the tumor grade will be misdiagnosed. In your case, the sample obtained via a needle biopsy, and according to the pathological report, is non-malignant, but we have to perform a surgery to remove it.
