Cerebrovascular accident, abbreviated CVA, is a common neurologic pathology. It is also known as a stroke.

Clinical classification:

Soft/mushy brain.
Older infarcts.
- A "roof" is present - a thin submeningeal layer is preserved by the CSF.^[1]
  - "Roof" is absent in trauma.
- Cavity - in older infarcts.
  - Multiple sclerosis does not cavitate.
Laminar necrosis = (thin) chalky line replaces grey mater.^[2]
- AKA pseudolaminar necrosis - as it is not localized to a specific layer of the cortex.^[3]
