B, Photomicrograph of histologic specimen of the splenium (same patient as in A) demonstrates a band of isomorphic gliosis (hematoxylin and eosin stain; original magnification, x60).
C, Axial FLAIR (10,000/156/1) image obtained in an 80-year-old man shows grade 1 signal intensity abnormality in the anterior subependymal region of the splenium.
D, Photomicrograph of histologic specimen of the splenium (same patient as in C) shows no gliosis (hematoxylin and eosin stain; original magnification, x60).
