The fracture in the left carotid canal was slightly displaced (Figure 1).
Axial CT scan image in the brain window, showing diffuse left hemispheric edema with
mass effect on the falx cerebri, probably linked to infarction.

Left fronto-parietal extra-dural hematoma, intra-parenchymal hematoma, subarachnoid hemorrhage and diffuse left hemispheric edema were associated (Figure 2).
Axial post contrast CT image in the arterial phase, in the soft tissue window, showing
a lack of opacification in the left internal carotid artery (Arrow).

(a) Axial post contrast CT image in the delayed phase, showing extravasation of
contrast into the left frontal extra-axial hematoma (orange asterisk). Note the left
frontal intra-parenchymal hematoma (blue asterisk), and the mass effect on the
homolateral lateral ventricle and the falx cerebri (arrows). (b) Sagittal reconstruction
post-contrast CT image in the delayed phase, showing extravasation of contrast into the
extra-axial hematoma (orange asterisk) and into the left sphenoidal sinus (red
asterisk). Also note the intra-parenchymal hematoma (blue asterisk).
