An urgent noncontrast computed tomography (CT) of the brain excluded acute vascular or posttraumatic lesions but showed an area of bone rarefaction localized in the parasagittal left parietal bone, associated with an ipsilateral parietal encephaloclastic cortical and subcortical brain lesion (Figure 1).
Sagittal T1-weighted images without and with contrast show brain herniation to the bone defect, without enhancement.
