"The bleed in relation to the dura mater is the key anatomical difference between an extradural and a subdural haemorrhage. As a student, a helpful tip is to remember that the dura tightly adheres to the intracranial bony sutures. Thus, an extradural haemorrhage is confined within that space, often producing a biconvex (also called lentiform) shape on CT."
