Parietal (16.5%), frontal (15.2%), and frontoparietal (10.1%) locations were most commonly involved followed by occipitoparietal (6.3%), fronto-occipital (3.8%), cerebellar (2.5%), temporal (2.5%), and occipital (2.5%) locations.
The cortical visual system is known to be segregated into two anatomically and functionally distinct pathways: a ventral occipitotemporal pathway that subserves object perception and a dorsal occipitoparietal pathway that subserves object localization and visually guided action [29-31].
Clinically, infants with DP most often present with ipsilateral frontal bossing, ipsilateral occipitoparietal flattening, contralateral occipital bossing, and ipsilateral displacement of the ear anteriorly.
Even though pathophysiological data are scarce, on theoretical basis we can reason that the unbalance between primary and secondary cortices may be attributed to a local irritative activity produced by infections, with possible developing of electrical phenomena, as epileptiform seizures and/or CSD, as suggested by reports  in which local occipitoparietal intermittent slowing of EEG was found in patients with AIWS, together with CSF leukocytosis, during the acute phase of the disturbance.
The patient's medical situation progressively worsened and follow-up CT scan of the brain revealed development of new hypodensities noted in the right posterior occipitoparietal, left occipital, and bilateral frontal regions.
