Though much faster than chronic subdural bleeds, acute subdural bleeding is usually venous and therefore slower than the arterial bleeding of an epidural hemorrhage. Acute subdural hematomas due to trauma are the most lethal of all head injuries and have a high mortality rate if they are not rapidly treated with surgical decompression. [23]
A subdural hygroma (SDG) is a collection of cerebrospinal fluid (CSF), without blood, located under the dural membrane of the brain. Most subdural hygromas are believed to be derived from chronic subdural hematomas. They are commonly seen in elderly people after minor trauma but can also be seen in children following infection or trauma.
On axial imaging of MRI at the level of the denticulate ligaments, the inverted Mercedes-Benz sign denotes the form taken on by a spinal subdural hematoma. To identify the hematoma in the spinal cord, MRI with and without gadolinium enhancement is the preferred choice. [ 9 ]
Treatment depends on the recovery stage of the patient. In the acute stage, the primary aim is to stabilize the patient and focus on preventing further injury. This is done because the initial damage caused by trauma cannot be reversed. [92] Rehabilitation is the main treatment for the subacute and chronic stages of recovery. [92]
Subdural hematoma maybe less acute than epidural hematoma due to slower blood accumulation, but it still has the potential to cause brain herniation that may require surgical evacuation. [3] Clinical features depend on the site of injury and severity of injury. Patients may have a history of loss of consciousness but they recover and do not ...
A venous hematoma may be acute (occurring within a day of the injury and appearing as a swirling mass of blood without a clot), subacute (occurring in 2–4 days and appearing solid), or chronic (occurring in 7–20 days and appearing mixed or lucent). [3] In adults, the temporal region accounts for 75% of cases.
Physiotherapists also play a significant role in rehabilitation after a brain injury. In the case of a traumatic brain injury (TBI), physiotherapy treatment during the post-acute phase may include sensory stimulation, serial casting and splinting, fitness and aerobic training, and functional training.

Most cases of primary intraparenchymal hemorrhage are the result of chronic hypertension (high blood pressure), cerebral amyloid angiopathy, or both. While these are the causative processes for most cases, a number of other pathological processes are known to accelerate or worsen them, including coagulopathy , vasculitis , brain tumors ...
