Skull shape is abnormal, non-visualized parieto-occipital and coronal sutures.  Sagittal suture is partially seen. There is evidence of exopthalmos because of shallow orbits. Skull shows lacunar defects/ Lueckenschaedel -appearance. Middle cranial fossa is pushed downwaord and forward. Findings are consistent with craniosynostosis (oxycephaly possible) .

Lacunar skull appearance;  Also known as: craniolacunia, mesenchymal dysplasia, may appear normal after several yrs associated with: Chiari malformation (almost always !), In contrast, increased intracranial pressure has: beaten-silver appearance, closed sutures, with or without abnormal skull size (Lueckenschaedel) So lacunar skull is synonym to “ Lueckenschaedel "
