9. Brain, Acute Infarct - High Power
These are acutely necrotic pyramidal neurons from the infarct in the
left lateral frontal lobe of this patient. The image also contains
non-necrotic neurons for comparison. Non-necrotic neurons have
amphophilic cytoplasm and a vesicular nucleus, with a nucleolus
sometimes visible. Acutely necrotic neurons have eosinophilic
cytoplasm and a hyperchromatic, pyknotic nucleus with no visible
nucleolus.
