Blast-induced intraventricular and intracerebral hemorrhage 10 months after blast exposure. H&E stained sections from rats sacrificed 10 months after receiving 3 × 74.5 kPa blast exposures. Panel A shows a ventricular hemorrhage (arrow) near the fimbria that may have originated in the choroid plexus. Panel B shows a matching section from a control animal. Panels C and D show hemorrhages (arrows) in the third ventricle (C) and next to the periventricular nucleus (D) from two additional blast-exposed rats. Scale bar: 200 μm A-B; 100 μm C-D.
