(Dr Sudhir Gupta, Additional Prof,
Forensic Medicine & Toxicology, AIIMS)
- The flax
cerebri and tentorium divide the cranial cavity into three communicating
compartments and have a partly restraining effect on brain movements.
- Injuries
like contusion and lacerations of the brain seen in vehicular accidents
and falls from heights are caused by the application of violence to the
head and may occur with or without external injury to the scalp and
fracture of the skull.
- Injuries
may be seen superficially anywhere on the surface of the brain, though the
commonest site is the outer surface of the parietal and temporal lobes or
deep within the brain substance and are associated with hemorrhages
limited in small areas or multiple hemorrhages diffused largely within the
brain tissues. They are also associated with disturbances of cerebrospinal
fluid circulation.
- These
injuries, also known as coup lesions,
are commonly found under the site of application of the blow, but are also
sometimes found particularly during autopsy on the surface of the brain
diagonally opposite the site of impact, and are called countercoup injuries.
- Coup
injuries are most commonly found on the frontal lobes and near the tips of
the temporal and frontal poles, rarely on the occipital poles. They are
usually severe injuries.
