This case highlights one of the features that differentiates an extradural hemorrhage from a subdural hemorrhage - that is, EDH may cross a dural reflection - in this case, the falx. Interestingly, it does not uphold the caveat that an EDH may not cross a suture line, freely crossing the saggital surture.

There is however an associated fracture extending into the saggital suture, and this and the probable injury to the superior saggital sinus, likely account for this EDH disrespecting the suture line.
