Epidural Hemorrhage

Findings
The CT scans show a lens-shaped, biconvex high attenuation collection in the posterior left parietal lobe exerting mass effect.

Discussion
Acute bleeds present with high attenuation on CT. Epidural hematomas are due to traumatic head injuries which causes bleeding between the inner table of the skull and the dura. The majority are in the temporo-parietal region where a skull fracture causes damage to the middle meningeal artery or one of its branches. EDHs may cross the midline but do not cross suture lines.
