- Caused by laceration of meningeal arteries ( middle )
- Sometimes Associated with skull fractures ( temporal bone )
- Lenticular ( biconvex ) hematomas on CT scan.

Sign and symptoms:
+/- initial loss of consciousness
50% have lucid interval for several hours followed by obtundation ( patient recovers then deteriorate)
Nausa and vomiting, loss of consciousness and seizures

2- Subdural hemorrhage
- Caused by laceration of the bridging corrical veins.
- More common in elderly 2ry to brain atrophy.
- Vomiting, weakness, confusion, headache, memory loss, speech disturbance and seizure.
