ACUTE NONHEMORRHAGIC
LEFT FRONTAL INFARCT
View image
The arrows point
to the abnormality. There is loss of the normal gray/white differentiation
of the cerebral cortex. Also note the loss of the normal sulcal
pattern. There is loss of the normal distinct architecture of
the underlying white matter. Note that there are no areas of
high attenuation within this region to suggest the presence
of hemorrhage. If present, it would place the patient at a high
risk for anticoagulant therapy.
MATURING LEFT FRONTAL
NONHEMORRHAGIC INFARCT
View second image
The arrows point
to the area of more well defined low attenuation within the
left frontal lobe. With loss of the normal sulcal pattern within
this region. There are no areas of high attenuation to suggest
the presence of hemorrhage. This is characteristic of a subacute
infarct.

third image
The arrows point
to the presence of low attenuation within the left frontal region.
Again is noted the absence of the normal sulcal pattern within
this region, however the attenuation coefficients are progressively
lower than that on the previous exam. This represents an infarct
in stages of evolution. Again, there is no hemorrhage.
