Figure 3b. Bilateral type I VR spaces in a 6-year-old boy. (a) Axial proton-density–weighted image (repetition time msec/echo time msec = 2375/100) shows hyperintense areas (arrows) in the anterior perforated substance on both sides. (b) Axial fluid-attenuated inversion-recovery (FLAIR) image (6606/100) obtained at the same level shows that these areas have CSF-like content (arrows). The signal intensity of the surrounding brain parenchyma is normal. (c, d) Diffusion-weighted image (2574/81; b factor = 1000 sec/mm2) (c) and corresponding apparent diffusion coefficient map (d) show no restricted diffusion in these areas (arrows).
