# | '''Cerebrovascular accident''', abbreviated '''CVA''', is a common neurologic pathology. It is also known as a '''stroke'''. | ||
==General== | |||
*Very common. | |||
*Leading cause of morbidity and mortality. | |||
Clinical classification: | |||
# Hemorrhagic stroke. | |||
# Ischemic stroke. | |||
==Gross== | |||
*Soft/mushy brain. | |||
*Older [[infarct]]s. | |||
**A "roof" is present - a thin submeningeal layer is preserved by the CSF.<ref>MUN. 16 December 2009.</ref> | |||
***"Roof" is absent in trauma. | |||
**Cavity - in older infarcts. | |||
***''[[Multiple sclerosis]]'' does not cavitate. | |||
*Laminar necrosis = (thin) chalky line replaces grey mater.<ref>URL: [http://moon.ouhsc.edu/kfung/jty1/neurotest/Q03-Ans.htm http://moon.ouhsc.edu/kfung/jty1/neurotest/Q03-Ans.htm]. Accessed on: 26 October 2010.</ref> | |||
