<prompt> Which of the following necrosis occurs characteristically in brain infarcts?Caseous necrosisFibrinoid necrosisCoagulative necrosisLiquefactive necrosis  <response>: CNS parenchymal infarcts organize an influx of macrophages into the area of necrosis. The macrophages ingest the lipid-rich, necrotic parenchyma, ultimately conveing the area to a fluid-filled cavity liquefactive necrosis. This process is usually complete by about 6 months after the development of the infarct.
