Symptoms of chronic subdural hematomas are usually delayed more than three weeks after injury. [1] If the bleeds are large enough to put pressure on the brain, signs of increased intracranial pressure or brain damage will be present. [3] Other symptoms of subdural hematoma can include any combination of the following: [7]
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 ...

More common in adults than in children, intraparenchymal bleeds are usually due to penetrating head trauma, but can also be due to depressed skull fractures. Acceleration-deceleration trauma, [ 24 ] [ 25 ] [ 26 ] rupture of an aneurysm or arteriovenous malformation (AVM), and bleeding within a tumor are additional causes.
Hematomas, also focal lesions, are collections of blood in or around the brain that can result from hemorrhage. [11] Intracerebral hemorrhage, with bleeding in the brain tissue itself, is an intra-axial lesion. Extra-axial lesions include epidural hematoma, subdural hematoma, subarachnoid hemorrhage, and intraventricular hemorrhage. [38]
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. One of the common causes of subdural hygroma is a sudden decrease in pressure as a result of placing a ventricular shunt.
Intracerebral hemorrhages is a severe condition requiring prompt medical attention. Treatment goals include lifesaving interventions, supportive measures, and control of symptoms. Treatment depends on the location, extent, and cause of the bleeding. Often, treatment can reverse the damage that has been done.
Intraventricular hemorrhage (IVH) refers to bleeding into the brain's ventricular system, where cerebrospinal fluid (CSF) is produced and circulates. IVH can occur in both neonates and adults, but the mechanisms differ based on age and underlying causes. --- **1. Neonatal IVH** (Common in Premature Infants) **Pathophysiology**
