<prompt> Lucid interval is classically seen in:Epidural hemorrhageSubdural hemorrhageIntraparenchymal hemorrhageNone of the above  <response>: Epidural hemorrhage has a classic three-stage clinical presentation that is probably seen in only 20 of cases. The patient is initially unconscious from the concussive aspect of the head trauma. The patient then awakens and has a lucid interval while the hematoma subclinically expands. As the volume of the hematoma grows, the decompensated region of the pressure-volume curve is reached, ICP increases, and the patient becomes lethargic and herniates. Uncal herniation from an EDH classically causes ipsilateral third nerve palsy and contralateral hemiparesis. Ref: Schwazs principle of surgery 9th edition, chapter 42.
