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

General

Clinical classification:

  1. Hemorrhagic stroke.
  2. Ischemic stroke.

Gross

  • Soft/mushy brain.
  • Older infarcts.
    • A "roof" is present - a thin submeningeal layer is preserved by the CSF.[2]
      • "Roof" is absent in trauma.
    • Cavity - in older infarcts.
  • Laminar necrosis = (thin) chalky line replaces grey mater.[3]
    • AKA pseudolaminar necrosis - as it is not localized to a specific layer of the cortex.[4]
