What is Tentorial hemorrhage?
Tentorial hematoma was defined as hyperdensity in posterior fossa near tentorium ceribelli with hounsefield unit of 60-90 on plain CT head.
What type of CT is used for subdural hematoma?
On noncontrast CT scan, an acute subdural hematoma appears as a hyperdense (white), crescent-shaped mass between the inner table of the skull and the surface of the cerebral hemisphere (see the images below).
What is SDH medical abbreviation?
A subdural hematoma (SDH) is a common neurosurgical disorder that often requires surgical intervention. It is a type of intracranial hemorrhage that occurs beneath the dura (essentially, a collection of blood over the surface of the brain) and may be associated with other brain injuries (see the images below).
What is the Tentorial leaflet?
Definition. The tentorium cerebelli is an invagination of dura mater that separates the occipital and temporal lobes of the cerebrum from the cerebellum and brainstem. Attachments. Anterior margin: Anterior clinoid process. Lateral margin: Superior border of the petrous part of the temporal bone, posterior clinoid …
Which diagnostic test is the best to diagnose a subdural hematoma?
Brain scans Most people with a suspected subdural haematoma will have a CT scan to confirm the diagnosis. A CT scan uses X-rays and a computer to create detailed images of the inside of your body. It can show whether any blood has collected between your skull and your brain.
Is a SDH considered a TBI?
Bleeding into this space is called a subdural hemorrhage. Other names for subdural hematoma are subdural hemorrhage or intracranial hematoma. More broadly, it is also a type of traumatic brain injury (TBI).
What forms the tentorial notch?
The tentorial notch (also known as the tentorial incisure or incisura tentorii) refers to the anterior opening between the free edge of the cerebellar tentorium and the clivus for the passage of the brainstem. The midbrain continues with the thalamus of the diencephalon through the tentorial notch.
What passes through the tentorial notch?
Midbrain passes through the tentorial notch and this notch provides the only communication between the supratentorial and infratentorial compartments. The area between the brainstem and free tentorial edge is divided into the anterior, middle, and posterior incisural spaces.
What does a CT scan of a subdural hematoma look like?
Subdural Hematoma (Subacute). On CT scan, the findings may be subtle – acute blood is bright; chronic blood is dark, but subacute blood may be isointense, as in this case. If one looks closely, one can see that all the sulci in the right hemisphere are effaced, but are normal in the left hemisphere.
