A Forehead
B Temporal bone

C Occipital bone
D Jaw

Ans. B

C. Extradural hematoma

Most common cause - Trauma to temporal bone (Temporal bone fracture).

Blood vessel involved are – Rupture of middle meningeal artery & vein.

The clinical presentation:

1). Sudden onset of altered sensorium

2). After some time patient regain consciousness for a short period (Lucid interval)

3). Patient again become unconscious.

Diagnosis: CT scan

Treatment: Urgent Burr hole surgery.

Extra Edge:

1). Coma with a dilated pupil after a lucid interval following a head injury must be assumed to represent an epidural hematoma.

2). Emergency evacuation of the clot without time-consuming studies is vital to restore cerebral function. With a patient in less critical condition, a CT scan is the appropriate diagnostic study.
