BRAIN INJURIES IN CT

  1. 1. BRAIN INJURIES IN CT PRESENTED BY: RAKESH VALLITTAYIL
  2. 2. BRAIN INJURY ANY INJURY OCCURING IN BRAIN OF A LIVING ORGANISM BRAIN DAMAGE- DISTRUCTION OR DEGENERATION OF BRAIN CELLS. TRAUMATIC BRAIN INJURY – DAMAGE OCCURES WHEN OUT SIDE FORCE TRAUMATICALLY INJURES THE BRAIN. STROKE – VASCULAR EVENT WHEN CAUSING DAMAGE TO BRAIN. AQUIRED BRAIN INJURY – DAMGE AFTER BIRTH EITHER TRAUMATIC OR NOT TRAUMATIC OR DUE TO OUT SIDE OR INSIDE
  3. 3. SKULL FRACTURE A skull fracture is a break in one or more of the eight bones that form the cranial portion of the SKULL. TYPES Linear Depressed Diastatic Basilar
  4. 4. LINEAR FRACTURES  BREAK IN BONE THAT TRAVERSE FULL THICKNESS OF BONE THE SKULL FROM OUTER TO INNER SHELL  MOST common  USUALLY REQUIRES NO INTERVENTIONS  BLUNT FORCE TRAUMA
  5. 5. DEPRESSED SKULL FRACTURE  WHEN THE BROCKEN PORTION DISPLACED INWARD  DUE TO BLUNT FORCE TRAUMA  HIGH RISK DUE TO PRESSURE ON THE BRAIN OR HEMORRHAGE.
  6. 6. DIASTIC FRACTURE WHEN THE FRACTURE LINE TRANSVERES ONE OR MORE SUTURES OF THE SKULL CAUSING WIDENING OF SUTURE. USUALLY SEEN IN CHILDREN
  7. 7. BASILAR FRACTURE  LINEAR FRACTURES OCCURE IN SKULL BASE INCLUDING SPHENOID ETHMOID TEMPORAL AND OCCIPITAL BONE.  VERY RARE TYPE OF FRACTURE
  8. 8. INTRACRANIAL HEMORRHAGE INTRA AXIAL HEMORRHAGE (INSIDE THE BRAIN TISSUE) INTRA CEREBRAL HEMMORRHAGE (ICH) CEREBRAL CONTUSION EXTRA AXIAL HEMORRHAGE (OUT SIDE THE BRAIN TISSUE) EXTRADURAL HEMMORRHAGE (EDH) SUBDURAL HEMMORRHAGE (SDH) SUBARACHANOID HEMMORRHAGE (SAH) INTRAVENTRICULAR HEMMORRHAGE (IVH)
  9. 9. INTRA CEREBRAL HEMMORRHAGE (ICH) OVAL OR ROUND SHAPED SINGLE OR MULTIPLE COMMON LOCATION IS BASAL GANGLIA IT MAY EXTEND TO VENTRICLES. CAN BE DUE TO HYPERTANSION,TRAUMA,ANEURI SM AND AVM. IT CAN CAUSE MASS EFFECT
  10. 10. CEREBRAL CONTUSIONS  BRUISE OF THE BRAIN TISSUE  SMALL –DANGEROUS BECAUSE IT  WILL CAUSE AXION DAMAGE.  LARGE-LESS DANGEROUS.
  11. 11. MENINGES THE MEMBRAINS THAT ENVELOP THE BRAIN. 1. DURA MATER – OUTER 2. ARACHANOID MATER –MIDDLE 3. PIA MATER- INNER
  12. 12. EXTRADURAL OR EPI DURAL HEMORRHAGE (EDH) BETWEEN INNER SURFACE OF THE SKULL AND OUTER LAYER OF DURA. ASSOCIATED WITH FRACTURE ARTERIAL BLOOD BICONVEX IN SHAPE
  13. 13. SUBDURAL HEMATOMA BETWEEN DURA MATTER AND THE BRAIN RESULTING IN TEARING OF VENOUS BRIDGE VENOUS BLOOD CRESCENT SHAPED ACUTE SDH: DUE TO TRAUMA MOST LETHAL CHRONIC SDH:OVER A PERIOD OF TIME PROGNOSIS -GOOD
  14. 14. EDH VS SDH
  15. 15. SUB ARACHANOID HEMORRHAGE (SAH) BLEEDING INTO SUB ARACHANOID SPACE FROM CEREBRAL ANEURISM OR INJURY
  16. 16. INTRAVENTRICULAR HEMORRHAGE (IVH) BLEEDING INTO VENTRICULAR SYSTEM DUE TO TRAUMA OR STROKE COMMON IN PREMATURE INFANTS IT WILL INCREASE THE INTRACRANIAL PRESSURE WHICH CAN RESULT IN FATAL BRAIN HERNIATION
