An intraparenchymal hemorrhage is a bleed within the brain tissue. It differs from subdural or epidural hematomas because they occur only in the outer and middle coverings of the brain, whereas an intraparechymal hemorrhage is within the brain itself.
This type of hemorrhage sometimes occurs as an extension of a subdural or epidural hematoma.

• Numbness or paralysis in some areas

What Causes Intraparenchymal hemorrhage?
Trauma can cause intraparenchymal hemorrhage but there are also many other causes such as high blood pressure, brain tumor, bleeding disorders, sickle cell disease, artery malformations and eclampsia of pregnancy. Additional causes are having had a previous cerebral aneurysm or weakened blood vessels, drug abuse and taking blood thinning medication like anticoagulants. Sometimes premature infants may also have this type of brain hemorrhage due to weakened vessels in their head, or infection.
The condition is diagnosed by a CT scan or MRI of the head. A cerebral angiography may also be done to identify any problems with the blood vessels in the brain. This is when a catheter is placed up through the main blood vessels in the abdomen and up into an artery in the neck.
Then a contrast dye is inserted that travels up to the blood vessels in the brain. This illuminates them on an X-ray picture so that any blockages in the flow of blood can be seen. The patient will be given local anaesthetic to minimize any discomfort they might feel from this procedure.
Treatment involves surgery to remove the excess blood, usually by removing part of the skull to drain the blood away. This will decrease the pressure on the brain and lessen the likelihood of permanent brain damage or death. Any bleeding vessels will be tied off.
