Figure 28: Axial non-contrast brain CT scan in a trauma patient. Bone window (a) shows a linear skull fracture (arrow in a). The location of the fracture near middle meningeal artery and presence of pneumocephalus (arrowheads in a and b) warrants further evaluation. Parenchymal window (b) depicts an epidural hematoma (arrow in b) that is secondary to the rupture of middle meningeal artery.
