Magnetic resonance imaging (MRI) imaging in PRES typically reveals T2 and FLAIR symmetric reversible hyper intensities in a parieto-occipital
As deterioration of vision, a repeated MRI showed infarction in bilateral parieto-occipital
lobs and CTA revealed diffuse vasoconstriction involving in anterior and posterior circulation.
Latissimus dorsi is a valid option when a very large surface area is involved especially at the parieto-occipital
Brain imaging usually reveals vasogenic oedema in the parieto-occipital
region with sparing of calcarine and paramedian parts of the occipital lobes , as shown in this case.
A newborn baby boy delivered through elective cesarean section at 38 weeks of gestation to a multigravida mother with normal APGAR, was noted to have a circular area of absent skin on parieto-occipital
region of scalp measuring 2.0 cm x 2.0 cm.
Posterior cortical atrophy (PCA) is a syndrome where the brain atrophy is more prevalent in the posterior aspect of the parieto-occipital
Her physical examination found an immobile nodular lesion of 2.5 X 2 X 2 cm localized to the left parieto-occipital
region and elevated from the skin with sporadic bleeding spots and small sites of ulceration (Figure 1).
Irregular, white calcifications at the cortical-white matter border were visible, mostly in the frontal and to a much lesser extent in the parieto-occipital
regions but not in the temporal lobes (Figures 2, B and C, and 3).

On magnetic resonance imaging (MRI), hyperintensity on T2-weighted (T2W) and fluid-attenuated inversion recovery (FLAIR) images in the parieto-occipital
and posterior frontal cortical and subcortical white matter is most commonly involved in the typical appearance of PRES.
Subsequently, she underwent magnetic resonance imaging with findings of an abnormal signal intensity of white matter involving both parieto-occipital
regions that appear iso-intense to gray matter on T1, hyper-intense on T2, and not suppressed on FLAIR, which confirmed the diagnosis (Figure 2).
The awake and asleep EEG revealed slowing of background rhythm over the left parieto-occipital
area with no epileptiform discharges.
