Which of the following necrosis occurs characteristically in brain infarcts? 
Select and explain. 
A. Caseous necrosis, B. Fibrinoid necrosis, C. Coagulative necrosis, D. Liquefactive necrosis
D: Liquefactive necrosis
Answer: D: Liquefactive necrosis 
Explanation: 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.
