Figure 2 Multiple arachnoid granulations (arrows) in a 56-year-old man. A-C: Sagittal T1-weighted image (T1WI) (A) showed hypointensity relative to the brain, axial (B) and sagittal (C) T2-weighted image showed hyperintensity relative to the brain, with a banded lower signal most likely representing the intra-arachnoid granulations (AGs) collagenous connective tissue; D: Axial fluid attenuated inversion recovery image demonstrated complete suppression of intra-AG fluid; E, F: Axial diffusion-weighted imaging (E) showed no restricted diffusion. Sagittal postcontrast T1WI (F) showed no gadolinium enhancement.
