FIG 1. Patient 6.
A and B, Postmortem gradient-echo T2*-weighted MR images (600/15/2; flip angle, 25°) show foci of signal hypointensity in the basal ganglia bilaterally and in the left thalamus (arrows, A). Note signal loss at the surface of the specimen due to field inhomogeneity and subarachnoid blood. Foci of signal loss are also noted in the cerebellum and pons (arrow, B).
C, Histopathologic section shows an old microbleed (arrow), corresponding to the largest hypointensity (corresponding arrows in B and C).
