Intraparenchymal hemorrhage is one form of intracerebral bleeding in which there is bleeding within brain parenchyma. The other form is intraventricular hemorrhage). [1] Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders.
Intracerebral hemorrhage (ICH), also known as hemorrhagic stroke, is a sudden bleeding into the tissues of the brain (i.e. the parenchyma), into its ventricles, or into both. [ 3 ] [ 4 ] [ 1 ] An ICH is a type of bleeding within the skull and one kind of stroke (ischemic stroke being the other).
Contusions are more commonly seen in the brain parenchyma near base of the skull such as inferior frontal lobes and temporal lobes as a result of Coup contrecoup injury. Those with parenchymal contusion would require frequent follow-up imaging because such contusions may grow large enough to become hemorrhage and exerts significant mass effect ...
Cerebral softening, also known as encephalomalacia, is a localized softening of the substance of the brain, due to bleeding or inflammation. Three varieties, distinguished by their color and representing different stages of the disease progress, are known respectively as red, yellow, and white softening.
A subdural hematoma (SDH) is a type of bleeding in which a collection of blood—usually but not always associated with a traumatic brain injury—gathers between the inner layer of the dura mater and the arachnoid mater of the meninges surrounding the brain.
In adults, the temporal region accounts for 75% of cases. In children, however, they occur with similar frequency in the occipital , frontal , and posterior fossa regions. [ 3 ] Epidural bleeds from arteries can grow until they reach their peak size 6–8 hours post-injury, spilling 25–75 cubic centimeters of blood into the intracranial space ...

The protuberances are located on the inside of the skull under the frontal and temporal lobes and on the roof of the ocular orbit. [9] Thus, the tips of the frontal and temporal lobes located near the bony ridges in the skull are areas where contusions frequently occur and are most severe. [10]
