Intracranial hemorrhage; Axiali CT scan of a spontaneous intracranial hemorrhage: Specialty: Emergency medicine : Symptoms: Same symptoms as ischemic stroke, but unconsciousness, headache, nausea, stiff neck, and seizures are more often in brain hemorrhages than ischemic strokes
The risk of death from an intraparenchymal bleed in traumatic brain injury is especially high when the injury occurs in the brain stem. [48] Intraparenchymal bleeds within the medulla oblongata are almost always fatal, because they cause damage to cranial nerve X, the vagus nerve, which plays an important role in blood circulation and breathing ...
Abnormal posturing is an involuntary flexion or extension of the arms and legs, indicating severe brain injury.It occurs when one set of muscles becomes incapacitated while the opposing set is not, and an external stimulus such as pain causes the working set of muscles to contract. [1]

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.
A burst lobe is an intracranial hemorrhage affecting a brain lobe (part of the cerebral hemispheres) and characterized by an intracerebral hemorrhage in continuity with a subdural hemorrhage and contusion. [1] On a CT scan, it is shown as an irregular area of increased density which corresponds to a blood clot.
While this bleeding can result in further injury, it is itself a marker for injury that has already occurred. Most intraventricular hemorrhages occur in the first 72 hours after birth. [9] The risk is increased with use of extracorporeal membrane oxygenation in preterm infants. [10] Congenital cytomegalovirus infection can be an important cause ...
A subdural hematoma (SDH) is a type of bleeding in which a collection of blood—usually but not always associated with a traumatic brain injury—gathers between the inner layer of the dura mater and the arachnoid mater of the meninges surrounding the brain. It usually results from rips in bridging veins that cross the subdural space.
