What is ex-vacuo dilatation?
Ex Vacuo dilatation is the medical term used for a space created
by a procedure. Foe example a patient who has a brain tumor removed
from the left side of brain will have an extra space at that site.
In comparison to the right side we see the volume to be less on
left side. The space between the convulsions is more on left as
more space is available. Sometimes the right part of the brain also
moves to the left which we call midline shift. This can happen in
places with closed compartments like the skull and chest where the
space is limited and nonexpansile. Hope its simple to understand.
