Epidural hematoma is when bleeding occurs between the tough outer membrane covering the brain (dura mater) and the skull. [4] When this condition occurs in the spinal canal, it is known as a spinal epidural hematoma. [4] There may be loss of consciousness following a head injury, a brief regaining of consciousness, and then loss of ...
The anatomy of the epidural space is such that spinal epidural hematoma has a different presentation from intracranial epidural hematoma. In the spine, the epidural space contains loose fatty tissue and a network of large, thin-walled veins, referred to as the epidural venous plexus. The source of bleeding in spinal epidural hematoma is likely ...
Trauma is the most common cause of intracranial hemorrhage. It can cause epidural hemorrhage, subdural hemorrhage, and subarachnoid hemorrhage. Other condition such as hemorrhagic parenchymal contusion and cerebral microhemorrhages can also be caused by trauma. [3]
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]
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]
An injured middle meningeal artery is the most common cause of an epidural hematoma. A head injury (e.g., from a road traffic accident or sports injury) is required to rupture the artery. Emergency treatment requires decompression of the hematoma, usually by craniotomy. Subdural bleeding is usually venous in nature, rather than arterial ...
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 ...
intracranial hematoma – a condition in which a blood vessel ruptures causing a pool of blood to form around the brain (subdural hematoma) or between the brain and the skull (epidural hematoma). Intracranial hematoma causes an increase in pressure on the brain and requires immediate medical attention.
