Figure 1: T1W axial and T2W sagittal images demonstrate the hyper intense appearing lipoma (arrow heads in a) with both intra and extra cranial parts and a defect in the parietal bone (arrow head on b). An atretic parietal encephalocele (Red asterisk) and a band (arrow) connecting dorsal midbrain with the lipoma are noticeable. MR venogram demonstrates fenestrated superior sagittal sinus (arrow heads in c) and persistent falcine sinus (arrows in d). Per-operative photos show the midline skull defect (arrow heads in e) and the excised extra cranial portion of the lipoma
