Initial MRI. A: axial 3D T1 with gadolinium, B: coronal FLAIR T2. Tumefactive white matter lesion with gadolinium enhancement (A) and subtle cortical component with​
peripheral edema (B). A low-grade glioma was suspected.​
MRI study 10 days later. C: MPR 3D T1 with tractography of the pyramidal tract and language functional MRI (BOLD) study. D: coronal FLAIR T2. This second study was​
performed to depict anatomic landmarks of the lesion with the pyramidal tract (blue in C) and language areas (yellow-orange areas in C). More tumefaction and edema​
was also found in just 10 days (D).​

  1. Axial 3D T1 with gadolinium. MRI before stereotactic biopsy.
  2. Axial 3D T1 with gadolinium 4 months after treatment. The lesion has almost disappeared and there isn’t any enhancement.
  3. Axial 3D T1 with gadolinium 8 months after treatment shows the same findings as in B.
