Intracranial hemorrhage (ICH), also known as intracranial bleed, is bleeding within the skull. [1] Subtypes are intracerebral bleeds ( intraventricular bleeds and intraparenchymal bleeds ), subarachnoid bleeds , epidural bleeds , and subdural bleeds .
Subarachnoid hemorrhage may also occur in people who have had a head injury. Symptoms may include headache, decreased level of consciousness and hemiparesis (weakness of one side of the body). SAH is a frequent occurrence in traumatic brain injury and carries a poor prognosis if it is associated with deterioration in the level of consciousness ...
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).
If an aneurysm ruptures, blood leaks into the space around the brain. This is called a subarachnoid hemorrhage. Onset is usually sudden without prodrome, classically presenting as a "thunderclap headache" worse than previous headaches. [11] [12] Symptoms of a subarachnoid hemorrhage differ depending on the site and size of the aneurysm. [12]
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]
The broad term, "stroke" can be divided into three categories: brain ischemia, subarachnoid hemorrhage and intracerebral hemorrhage. Brain ischemia can be further subdivided, by cause, into thrombotic, embolic, and hypoperfusion. [3] Thrombotic and embolic are generally focal or multifocal in nature while hypoperfusion affects the brain globally.
Cerebral hemorrhage — a type of intracranial hemorrhage, bleeding within the brain tissue itself. Intracerebral hemorrhage — bleeding in the brain caused by the rupture of a blood vessel within the head. See also hemorrhagic stroke. Subarachnoid hemorrhage (SAH) implies the presence of blood within the subarachnoid space from some ...
Intraventricular hemorrhage (IVH), also known as intraventricular bleeding, is a bleeding into the brain's ventricular system, where the cerebrospinal fluid is produced and circulates through towards the subarachnoid space. It can result from physical trauma or from hemorrhagic stroke.
