| Patient No./Age/Sex | Chief Complaint | CT Scan/ Dual-Phase CT | MR Image | Location | Size* (mm) | Margin | Density on Precontrast CT Scan† | Signal Intensity on MR Imaging† | Enhancement Pattern/Degree | |

Note:—T1WI indicates T1-weighted image; T2WI, T2-weighted image.
* Size was denoted as greatest diameter.
† Density and signal intensity of the tumor were compared with those of the cerebral gray matter.
