Epidural hematoma (EDH) is usually caused by shear injury to an artery from a skull fracture. The most commonly injured vessel is the middle meningeal artery. Less than 10% of EDH are venous, most commonly from the middle meningeal vein, diploic vein, or venous sinus. The most common cause is trauma. Occasionally, EDH can be spontaneous from coagulopathy, thrombolysis, vascular malformation, neoplasm, epidural anesthesia, and Paget’s disease of the skull. They are rarely bilateral (Weissleder, Primer of diagnostic imaging. Elsevier, Philadelphia, 2011).
