- EDH is of course normally mid meningeal artery but also be:
- diploic veins (traversing the skull)
- venous sinuses
- mid meningeal vein (same course as the artery)
- the classic lucid period presentation of EDH is exception rather than the rule
- SDHs much more likely to have delayed presentations
- blood from an SDH can be isodense with brain about 7-14 days post event (see CT below)
- parenchymal contusion is the most common +ve finding over all
- cerebral vasospasm can occur after traumatic SAH but much less common than spontaneous SAH
Delayed SDH with midline shift and all that
