FileEarly Middle Cerebral Artery Infarction
CT of the brain demonstrates
effacement of the right Sylvian fissure and parietal sulci as
compared to the left. The gray-white matter interface is blurred
on the right and there is subtle lower attenuation of the brain
on the right.
Follow up CT 24 hours later shows diffuse
low attenuation in the right parietal region with moderate midline
shift to the left. The findings are compatible with infarction
in the right middle cerebral artery distribution. Notice the sparing
of the right frontal and occipital lobes which are supplied by
the anterior cerebral artery and posterior cerebral artery, respectively.
In this case, craniotomy was performed to
relieve pressure from the severe brain swelling. A ventriculostomy
tube was also placed.
