Figure 1 Serial brain fluid‐attenuated inversion recovery‐magnetic resonance imaging (FLAIR‐MRI) scans in the patient described here. (A–C) Axial sections including the Sylvian fissure; (D–F) axial sections through the upper brain stem; (G–I) coronal sections including the pons. For the time course, see the dates on the bottom of the figure. (G) As no coronal FLAIR or T2 images from December 2002 exist, this unusually angulated T2 section showing the pons (for orientation of slices, see the small image in the upper right corner of (G)) from July 2002 is used as a substitute. A slight atrophy of the left cerebellar hemisphere is also seen.
