Panel A. Intraoperative brain images in April 2004. An axial T1-weighted image after gadolinium injection (left-hand side) shows lesions in the gray matter of the left temporo-parietal lobe and right occipital lobe (place of biopsy). These images show slight enhancement of the lesions particularly in the meninges and the presence of mass effect. An axial T2-weighted image (center) and a FLAIR image (right-hand side) show better details of the lesions. Panel B. Brain MRI images, 5 months after discharge. Axial T-1 weighted image after gadolinium injection (left-hand side) showed important improvement in gray matter lesions. However, images in T2-weighted (center), and FLAIR (right-hand side) showed presence of new high-signal-intensity lesions in the white matter of the right frontal lobe and left occipital lobe. A widening of the right ventricle compared to the figure in Panel A can be observed. Panel C. Brain MRI images, 7 months after discharge. Axial T-1 weighted image after gadolinium injection (left-hand side) shows normal appearance. Images in T2-weighted (center) and FLAIR (right-hand side) reveal regression of the white matter changes; however discrete widening of the right ventricle is still present.
