u EDHs can cross the midline where the periosteal layer of the dura forms the outer wall of the superior sagittal sinus
u Dural line is seen
u Injury to a meningeal artery/vein, diploic vein, or dural venous sinus results in a classically lentiform-shaped collection of blood that strips the dura away from the inner table of the skull. EDHs are most common in the temporal or temporoparietal regions, often due to laceration of the middle meningeal artery or one of its branches .
Imaging of EDH
u EDH typically appear lentiform or biconvex in shape.
u EDH do not cross cranial sutures because the periosteal layer of the dura adheres tightly to the suture.
