Acute vascular injuries. a Coronal sections of brain hemispheres show bilateral intraparenchymal hemorrhage in frontal and parietal lobes. b The intraparenchymal hemorrhage obliterates the medial left hemisphere and extends into the left lateral, third, and fourth ventricles. c Microscopic examination confirms findings in the right parietal region. d Image from a H&E-stained section of prefrontal cortex demonstrates acute microscopic infarct (arrow) and acute subarachnoid hemorrhage (*). The inset in d shows red neurons, indicative of ischemic change. e Section of the hippocampus demonstrates acute ischemic changes (arrows) in CA1 neurons. Scale bar: 1 mm (a and b), 200 µm (d), and 100 µm (c and e)
