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.
Those with parenchymal contusion would require frequent follow-up imaging because such contusions may grow large enough to become hemorrhage and exerts significant mass effect on the brain. [3] Cerebral microhemorrhages is a smaller form of hemorrhagic parenchymal contusion and are typically found in white matter. Such microhemorrhages are ...
Intraparenchymal hemorrhage (IPH) is one form of intracerebral bleeding in which there is bleeding within brain parenchyma. [10] Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders.
Yellow softening is the third type of cerebral softening. As its name implies, the affected softened areas of the brain have a yellow appearance. This yellow appearance is due to atherosclerotic plaque build-up in interior brain arteries coupled with yellow lymph around the choroid plexus, which occurs in specific instances of brain trauma.

Symptoms of a ruptured aneurysm can include: [13] a sudden severe headache that can last from several hours to days; nausea and vomiting; drowsiness, confusion and/or loss of consciousness; visual abnormalities; meningism; dizziness; Almost all aneurysms rupture at their apex. This leads to hemorrhage in the subarachnoid space and sometimes in ...
Prognosis is very poor when IVH results from intracerebral hemorrhage related to high blood pressure and is even worse when hydrocephalus follows. [1] It can result in dangerous increases in ICP and can cause potentially fatal brain herniation. [1] Even independently, IVH can cause morbidity and mortality.
Cardiovascular and pulmonary symptoms may also be present as the brain loses function, but might also be associated with bleeding. These symptoms are known as Cushing's Triad: hypertension (with widening pulse pressure), irregular respirations (commonly Cheyne-Stokes), bradycardia and in severe cases cardiac arrest. [3] [4]
Subarachnoid hemorrhage may also occur in people who have had a head injury. Symptoms may include headache, decreased level of consciousness and hemiparesis (weakness of one side of the body). SAH is a frequent occurrence in traumatic brain injury and carries a poor prognosis if it is associated with deterioration in the level of consciousness ...
