About this trial
The registry of this study was subjected to patients who were radiologically diagnosed with a non-malignant brain tumor at Seoul National University Hospital since 2001, and who have had magnetic resonance (MR) re-examination after first MR exam or will be re-examined because it was determined that immediate treatment would not be needed at the first visit to the hospital. In all MRs taken by patients, the date of imaging and the volume of the tumor are measured, and we aim to establish a natural growth history for non-malignant brain tumors.
