"Differentiating extradural (EDH) from subdural (SDH) haemorrhage in the head is usually straightforward, but occasionally it can be challenging. SDHs are more common, and a few distinguishing features are usually reliable."

"Almost always arterial, explaining the progressive growth of the haematoma. Classically due to injury of the middle meningeal artery, a branch of the maxillary artery (from the ECA)."
"Typically crescentic (crescent moon-shaped, concave, banana-shaped) and more extensive than EDH, with the internal margin parallelling the cortical margin of the adjacent brain. As these occur in the subdural space, they cross sutures."
"EDH is treated with expedient evacuation via a craniotomy."
"SDH has various management strategies depending on the size, location and extent of mass effect and is either conservative (monitor with serial CT) or surgical (drainage with burr holes)."

"Typically lentiform (lens-shaped, biconvex, lemon-shaped) and do not cross sutures as the periosteum crosses through the suture continuous with the outer periosteal layer."
