A cerebral hemorrhage (also spelled haemorrhage) is a type of intracranial hemorrhage that occurs
within the brain tissue. It can be caused by brain trauma, or it can occur spontaneously in hemorrhagic
stroke. Non-traumatic intracerebral hemorrhage is a spontaneous bleeding into the brain tissue and
may be caused by increased exertion, tension or stress.[1]
A cerebral hemorrhage is an intra-axial hemorrhage; that is, it occurs within, rather than outside, the
brain tissue. The other category of intracranial hemorrhage is extra-axial hemorrhage, such as epidural,
subdural, and subarachnoid hematomas, which all occur within the skull but outside of the brain tissue.
There are two main kinds of intra-axial hemorrhages: intraparenchymal hemorrhage and
intraventricular hemorrhages. As with other types of hemorrhages within the skull, intraparenchymal
bleeds are a serious medical emergency because they can increase intracranial pressure, which if left
untreated can lead to coma and death. The mortality rate for intraparenchymal bleeds is over 40%.[2]
Signs and symptoms

2. Patients with intraparenchymal bleeds have symptoms that correspond to the functions controlled by
the area of the brain that is damaged by the bleed.[3] Other symptoms include those that indicate a rise
in intracranial pressure caused by a large mass putting pressure on the brain.[3] Intracerebral
hemorrhages are often misdiagnosed as subarachnoid hemorrhages due to the similarity in symptoms
and signs. A severe headache followed by vomiting is one of the more common symptoms of
intracerebral hemorrhage. Another common symptom is a patient can collapse. Some people may
experience continuous bleeding from the ear. Some patients may also go into a coma due to before the
bleed is noticed.
Causes
Splenial Infarct / Boomerang Sign, Sturge Weber Syndrome / Vein of Galen Malformation

Intracerebral bleeds are the second most common cause of stroke, accounting for 10% of hospital
admissions for stroke.[4] High blood pressure raises the risks of spontaneous intracerebral hemorrhage
by two to six times.[1] More common in adults than in children, intraparenchymal bleeds are usually due
to penetrating head trauma, but can also be due to depressed skull fractures. Acceleration-deceleration
trauma,[5][6][7] rupture of an aneurysm or arteriovenous malformation (AVM), and bleeding within a
tumor are additional causes. Amyloid angiopathy is a not uncommon cause of intracerebral hemorrhage
in patients over the age of 55. A very small proportion is due to cerebral venous sinus thrombosis.
Infection with the k serotype of Streptococcus mutans may also be a risk factor, because of its
prevalence in stroke patients and production of collagen-binding protein.[8]
Risk factors for ICH include:[9]
Hypertension (high blood pressure)
Diabetes mellitus
Menopause
Cigarette smoking
Excessive alcohol consumption

3. Severe migraine
Tramautic intracerebral hematomas are divided into acute and delayed. Acute intracerebral hematomas
occur at the time of the injury while delayed intracerebral hematomas have been reported from as early
as 6 hours post injury to as long as several weeks.
Diagnosis
Spontaneous ICH with hydrocephalus on CT scan[1]
Both computed tomography angiography (CTA) and magnetic resonance angiography (MRA) have been
proved to be effective in diagnosing intracranial vascular malformations after ICH.[10] So frequently, a
CT angiogram will be performed in order to exclude a secondary cause of hemorrhage[11] or to detect a
"spot sign".
Intraparenchymal hemorrhage can be recognized on CT scans because blood appears brighter than
other tissue and is separated from the inner table of the skull by brain tissue. The tissue surrounding a
bleed is often less dense than the rest of the brain because of edema, and therefore shows up darker on
the CT scan.[11]
Treatment
Treatment depends substantially of the type of ICH. Rapid CT scan and other diagnostic measures are
used to determine proper treatment, which may include both medication and surgery.
Medication
One review found that antihypertensive therapy to bring down the blood pressure in acute phases
appears to improve outcomes.[12] Another review found an unclear difference between intensive and
less intensive blood pressure control.[13] The American Heart Association and American Stroke
Association guidelines in 2015 recommended decreasing the blood pressure to a SBP of 140 mmHg.[14]
Giving Factor VIIa within 4 hours limits the bleeding and formation of a hematoma. However, it also
increases the risk of thromboembolism.[15] It thus overall does not result in better outcomes in those
without hemophilia.[16]
Mannitol is effective in acutely reducing raised intracranial pressure.

4. Acetaminophen may be needed to avoid hyperthermia, and to relieve headache.[15]
Frozen plasma, vitamin K, protamine, or platelet transfusions are given in case of a coagulopathy.[15]
Fosphenytoin or other anticonvulsant is given in case of seizures or lobar hemorrhage.[15]
H2 antagonists or proton pump inhibitors are commonly given for stress ulcer prophylaxis, a condition
somehow linked with ICH.[15]
Corticosteroids, were thought to reduce swelling. However, in large controlled studies, corticosteroids
haven been found to increase mortality rates and are no longer recommended.[17][18]
Glibenclamide (Glyburide), while not currently an FDA approved treatment, is being studied as a
promising treatment for preventing secondary brain injury and cerebral edema post-hemorrhage or
infarction.
Surgery
Surgery is required if the hematoma is greater than 3 cm (1 in), if there is a structural vascular lesion or
lobar hemorrhage in a young patient.[15]
A catheter may be passed into the brain vasculature to close off or dilate blood vessels, avoiding
invasive surgical procedures.[19]
Aspiration by stereotactic surgery or endoscopic drainage may be used in basal ganglia hemorrhages,
although successful reports are limited.[15]
Other treatment
Tracheal intubation is indicated in patients with decreased level of consciousness or other risk of airway
obstruction.[15]
IV fluids are given to maintain fluid balance, using isotonic rather than hypotonic fluids.[15]
Prognosis
The risk of death from an intraparenchymal bleed in traumatic brain injury is especially high when the
injury occurs in the brain stem.[2] Intraparenchymal bleeds within the medulla oblongata are almost
always fatal, because they cause damage to cranial nerve X, the vagus nerve, which plays an important
role in blood circulation and breathing.[5] This kind of hemorrhage can also occur in the cortex or
subcortical areas, usually in the frontal or temporal lobes when due to head injury, and sometimes in
the cerebellum.[5][20]

5. For spontaneous ICH seen on CT scan, the death rate (mortality) is 34–50% by 30 days after the insult,[1]
and half of the deaths occur in the first 2 days.[21] Even though the majority of deaths occurs in the first
days after ICH, survivors have a long term excess mortality of 27% compared to the general
population.[22]
The inflammatory response triggered by stroke has been viewed as harmful in the early stage, focusing
on blood-borne leukocytes, neutrophils and macrophages, and resident microglia and astrocytes.[23] A
human postmortem study shows that inflammation occurs early and persists for several days after
ICH.[24] New area of interest are the Mast Cells.[25]
Epidemiology
It accounts for 20% of all cases of cerebrovascular disease in the US, behind cerebral thrombosis (40%)
and cerebral embolism (30%).[26]
It is two or more times more prevalent in black patients than it is in white patients.[27]
