6. Brain, Remote Infarct - Low Power
Microscopic appearance of the remote (cavitary) infarct seen in the
last image. Note that the microscopic section traverses the cavitary
infarct in two places, but the cavities are connected elsewhere. Also
of note is the thin cortical ribbon under the pia mater, which is not
part of the infarct, because of its meningeal blood supply. The term
for this is "subpial sparing". In contrast, in a contusion, there is
no subpial sparing.
