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