These select sequences demonstrate an atrophic right hemisphere, with prominently ex vacuo dilated right lateral ventricle and gliosis/periventricular FLAIR hyperintensity. In addition, there is compensatory bony changes, with a large right frontal sinus, as well as right sided calvarial thickening and elevated petrous ridge. The falx is also deviated to the right.
The remainder study (not shown) is unremarkable.

In radiology, this so-called syndrome is more likely to represent a group of radiological findings that expresses a possible sequela of a fetal or early childhood period brain insult
