An arachnoid subdural hematoma is a type of bleeding that occurs between the arachnoid membrane and the dura mater, two layers of the protective membranes surrounding the brain. This condition typically arises from trauma or injury, leading to the accumulation of blood in this space, which can cause pressure on the brain. Symptoms may include headache, confusion, or neurological deficits, and treatment often involves monitoring or surgical intervention to alleviate pressure. It is distinct from other types of hematomas, such as epidural or subdural hematomas, due to its specific location and causes.

What is an epidural hematoma?
blood accumulation that separates the dura from the inner side of the skull is known as an epidural hematoma (blood swelling). The same process occurrence between the dura and arachnoid layers is a subdural hematoma
What is one difference between a subdural hematoma and an epidural hematoma?
A Subdural Hematoma occurs when a severe acceleration to deceleration occurs leading to the veins in the subdural space tearing. An Epidural Hematoma occurs from direct trauma to the brain leading to bleeding in the meningeal artery.
What is the difference between a intracerebral hematoma and subdural hematoma?
An intracerebral hematoma is a collection of blood from bleeding within the brain whereas a subdural hematoma is a collection of blood from bleeding outside the brain. The brain is covered by a membrane called the meninges which consists of three layers. The outermost layer is the dura mater, the middle layer is the arachnoid mater while the innermost layer which is adjacent to the outer surface of the brain is the pia mater. A subdural hematoma is therefore more specifically a collection of blood between the dura and arachnoid layers.
Can dehydration cause subdural hematoma?
no
Where does the subdural space lie between?
The subdural space lies between the dural and arachnoid layers of the meninges.
What is a mass or tumor of blood in the head?
subdural hematoma
What is the icd 9 code for chronic subdural hematoma?
852.21
What the ICD-9-CM code for subdural hematoma?
432.1
How serious is a subdural hematoma?
Symptoms appearing in less than 48 hours are due to an acute subdural hematoma. This type of bleeding is often fatal, and results from tearing of the venous sinus.
What is the medical term meaning active bleeding between the skull and the brain?
It depends where the bleeding is. If it is in the brain tissue then cerebral hemorrhage is correct. In the subarachnoid space would be a subarachnoid hematoma. In the subdural space.....subdural hematoma.haemorage
How long after head trauma can a subdural hematoma develop?
A subdural hematoma can develop within hours to weeks after a head trauma, but it commonly occurs within the first 24 to 48 hours after the injury. It is important to monitor for symptoms of a subdural hematoma like headaches, confusion, and neurological deficits in the days following a head injury.
How is a diagnosis of subdural hematoma made?
The hematoma can be confirmed with magnetic resonance imaging (MRI), which is the preferred type of scan;
