Trauma is the most common cause of intracranial hemorrhage. It can cause epidural hemorrhage, subdural hemorrhage, and subarachnoid hemorrhage. Other condition such as hemorrhagic parenchymal contusion and cerebral microhemorrhages can also be caused by trauma. [3]
Hemorrhage into the basal ganglia or thalamus causes contralateral hemiplegia due to damage to the internal capsule. [7] Other possible symptoms include gaze palsies or hemisensory loss. [7] Intracerebral hemorrhage into the cerebellum may cause ataxia, vertigo, incoordination of limbs and vomiting. [7]
Intraparenchymal hemorrhage is one form of intracerebral bleeding in which there is bleeding within brain parenchyma. The other form is intraventricular hemorrhage). [1] Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders.
Some forms of stroke can cause additional symptoms. For example, in intracranial hemorrhage, the affected area may compress other structures. Most forms of stroke are not associated with a headache, apart from subarachnoid hemorrhage and cerebral venous thrombosis and occasionally intracerebral hemorrhage. [33]
A head injury may cause skull fracture, which may or may not be associated with injury to the brain. Some patients may have linear or depressed skull fractures. If intracranial hemorrhage occurs, a hematoma within the skull can put pressure on the brain.
In contrast, intracranial hemorrhage involves bleeding that is not mixed with tissue. [37] 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

The broad term, "stroke" can be divided into three categories: brain ischemia, subarachnoid hemorrhage and intracerebral hemorrhage. Brain ischemia can be further subdivided, by cause, into thrombotic, embolic, and hypoperfusion. [3] Thrombotic and embolic are generally focal or multifocal in nature while hypoperfusion affects the brain globally.
