Fig 5. Comparison of postmortem MR images and histologic findings in an 83-year-old subject. Postmortem axial (A) and coronal (B) T2-weighted images. A section corresponding to B stained with Klüver-Barrera (C), Berlin blue (D), and ferritin immunohistochemistry (E). A and B, Postmortem MR images show diffuse putaminal hypointensity, and HPR is not detectable. With Klüver-Barrera staining (C), myelinated fibers are few in the lateral marginal area of the putamen (dotted lines). With Berlin blue staining (D), hemosiderin is scattered in the inner portion of the putamen but is scarce in the outer portion. Ferritin immunohistochemistry reveals diffuse ferritin deposits in the putamen, including the lateral marginal area (E).
