A subarachnoid hemorrhage is an intracranial hemorrhage into the cerebrospinal fluid-filled space between the arachnoid and pial membranes on the surface of the brain. The cause may be trauma, rupture of an aneurysm, or an arteriovenous anomaly. The hemorrhage may extend into the brain if the force of the bleeding from the broken vessel is severe or sudden. Localized pain usually results from vascular injury and/or distortion.

What is sub brachia hemorrhage?
I think you are referring to "sub-arachnoid hemorrhage". This is a type of brain hemorrhage occurring underneath the arachnoid membrane which envelopes the brain and can be caused by bleedding from an aneurysm
What MRI misses that CT scan shows?
The classic answer is acute sub-arachnoid hemorrhage.
What is anintracerebral hemorrhage?
Intracerebral hemorrhage affects vessels within the brain itself, while subarachnoid hemorrhage affects arteries at the brain's surface, just below the protective arachnoid membrane.
What function reabsorbs cerebral spinal fluid back into the blood?
The function that reabsorbs cerebral spinal fluid back into the blood is called arachnoid villi or arachnoid granulations. These structures are responsible for draining CSF from the subarachnoid space into the bloodstream, helping to maintain the fluid balance in the brain.
What fluid is found in the sub-arachnoid space?
Cerebrospinal fluid (CSF) is the fluid found in the sub-arachnoid space. It surrounds the brain and spinal cord, providing cushioning and a protective barrier.
What is ICD 9 Code for submacular Hemorrhage?
362.81 Sub-Retinal Hemorrhage
What is the intermediate layer of the meninges?
middle layer of meninges is called arachnoid
How does age affect stroke risk?
Intracerebral hemorrhage affects vessels within the brain itself, while subarachnoid hemorrhage affects arteries at the brain's surface, just below the protective arachnoid membrane.
Why do you have the crazy urge to twitch your neck?
I have a need to twitch in my neck also. I would describe it more as a thrashIng to the side. It happens when I am tired. Usually this coincides with extremely powerful (actually painful) yawning. I wonder if this could be related to the sub arachnoid hemorrhage I had 3 years ago. Hope we find some answers.
What is ventral sub arachnoid space?
The ventral subarachnoid space is a region within the spinal cord where cerebrospinal fluid circulates. It is located between the arachnoid mater and pia mater layers surrounding the spinal cord. This space helps cushion and protect the spinal cord.
What will be the result if the fourth ventricle is blocked?
if the fourth ventricle is blocked it will result in accumulation of CSF and there is no drainage of CSF into the sub -arachnoid space.
Where does blood accumulate in subarachnoid hemorrhage?
Blood accumulates in the subarachnoid space, which is the area between the arachnoid membrane and the pia mater in the brain and spinal cord. Subarachnoid hemorrhage can occur due to the rupture of a blood vessel in this space, leading to bleeding and accumulation of blood that can cause serious neurological complications.
