Epidural Subdural Location Between the skull and the inner meningeal layer of the dura mater or between outer endosteal and inner meningeal layer of dura mater: Between the meningeal layers of dura mater and the Arachnoid mater: Involved vessel Temperoparietal locus (most likely) – Middle meningeal artery Frontal locus – anterior ethmoidal ...
Unlike epidural hematomas, which cannot expand past the sutures of the skull, subdural hematomas can expand along the inside of the skull, creating a concave shape that follows the curve of the brain, stopping only at dural reflections like the tentorium cerebelli and falx cerebri.

CT scans reveal subdural or epidural hematomas in 20% of unconscious people. [15] In the hallmark of epidural hematoma, people may regain consciousness and appear completely normal during what is called a lucid interval, only to descend suddenly and rapidly into unconsciousness later. This lucid interval, which depends on the extent of the ...
Hematomas, also focal lesions, are collections of blood in or around the brain that can result from hemorrhage. [11] Intracerebral hemorrhage, with bleeding in the brain tissue itself, is an intra-axial lesion. Extra-axial lesions include epidural hematoma, subdural hematoma, subarachnoid hemorrhage, and intraventricular hemorrhage. [38]
Traumatic subdural hematoma, a bleeding below the dura mater which may develop slowly; Traumatic extradural, or epidural hematoma, bleeding between the dura mater and the skull; Traumatic subarachnoid hemorrhage; Cerebral contusion, a bruise of the brain; Concussion, a loss of function due to trauma
Subdural hematoma maybe less acute than epidural hematoma due to slower blood accumulation, but it still has the potential to cause brain herniation that may require surgical evacuation. [3] Clinical features depend on the site of injury and severity of injury. Patients may have a history of loss of consciousness but they recover and do not ...

Subdermal hematoma (under the skin) Intramuscular hematoma (inside muscle tissue) Skull/brain: Subgaleal hematoma – between the galea aponeurosis and ...
Epidural hemorrhage is bleeding between the dura mater and the skull. [4] It is commonly associated with damage to the middle meningeal artery, often resulting from a skull fracture. Subdural hemorrhage is bleeding between the dura mater and the arachnoid. [4] Intracerebral hemorrhage is bleeding within the brain tissue itself. [4]
