1. BRAIN INJURIES IN CT By Mr. Dinesh Sekar M.Sc. Radiology Assistant Professor Department Of Radiology

2. BRAIN INJURY Any Injury Occurring In Brain Of A Living Organism Brain Damage- Destruction Or Degeneration Of Brain Cells. Traumatic Brain Injury – Damage Occurs When Out Side Force Traumatically Injures The Brain. Stroke – Vascular Event When Causing Damage To Brain. Acquired Brain Injury – Damage After Birth Either Traumatic Or Not Traumatic Or Due To Out Side Or Inside

3. SKULL FRACTURE A skull f r ac t u r e i s a bre ak i n one or more o f t he eight bon e s that f o r m the cranial portion of the SKULL. TYPES Linear D e pres se d Diastatic Basilar

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. 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. DIASTIC FRACTURE WHEN THE FRACTURE LINE TRANSVERES ONE OR MORE SUTURES OF THE SKULL CAUSING WIDENING OF SUTURE. USUALLY SEEN IN CHILDREN

7. BASILAR FRACTURE LINEAR FRACTURES OCCURE IN SKULL BASE INCLUDING SPHENOID ETHMOID TEMPORAL AND OCCIPITAL BONE. VERY RARE TYPE OF FRACTURE

8. Intracranial   Hemorrhage 🢝 Intra Axial Hemorrhage (Inside The Brain Tissue) Intra Cerebral Hemorrhage (Ich) Cerebral Contusion 🢝Extra Axial Hemorrhage (Out Side The Brain Tissue) Extradural Hemorrhage (EDH) Subdural Hemorrhage (SDH) Subarachnoid Hemorrhage (SAH) Intraventricular Hemorrhage (IVH)

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,ANEURISM AND AVM. IT CAN CAUSE MASS EFFECT

10. CEREBRAL CONTUSIONS BRUISE OF THE BRAIN TISSUE SMALL –DANGEROUS BECAUSE IT WILL CAUSE AXION DAMAGE. LARGE-LESS DANGEROUS.

11. MENINGES THE MEMBRAINS THAT ENVELOP THE BRAIN. DURA MATER – OUTER ARACHANOID MATER –MIDDLE PIA MATER- INNER

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. S U B D U R A L H E M A T O M A 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. EDH VS SDH

15. SUB ARACHANOID HEMORRHAGE (SAH) BLEEDING INTO SUB ARACHANOID SPACE FROM CEREBRAL ANEURISM OR INJURY

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
