Presentation transcript:

Corticobasal degeneration (CBD), case 1. Corticobasal degeneration (CBD), case 1. An 84-year-old woman. A, Axial T2-weighted image shows a high signal intensity in the right frontal subcortical white matter (white arrow). B, In a microscopic specimen of the right frontal lobe corresponding to the site of white matter lesions, myelin sheath staining is decreased (red oval). The scale is 1 mm. C, In this area, there is positive staining for antiphosphorylated tau antibody on AT8 staining, which is compatible with the primary changes in CBD. The scale is 50 μm. A.M. Tokumaru et al.
