Frontal – Depending on the size and location, frontal ICH may present with symptoms ranging from weakness of one limb to impaired consciousness with contralateral hemiparesis, hemisensory loss, and horizontal gaze palsy; left hemispheric lesions can present with aphasia, and more anterior lesions lead to an abulic state with frontal release signs.


Parenchymal features found in the brains of patients with CAA include patchy demyelination and loss of white matter, cortical hemorrhages angiopatia amiloide cerebral infarcts, and neuritic angiopatia amiloide cerebral with or without neurofibrillary angiopatia amiloide cerebral.

Some patients with CAA present with a progressive dementia, involving rapid cognitive decline over days or weeks.


Hematoma evacuation can be lifesaving when the hematoma causes significant mass effect and predisposes to herniation, particularly when medical management of increased intracranial pressure yields no response.

Images were analyzed from 82 subjects with post-mortem confirmation of the presence or absence of beta-amyloid neuritic plaques. The diagnosis of CAA is based on a clinical history compatible, neuroimaging showing hemosiderosis or multiple bleeding, predominantly in posterior fossa, and in some cases histological examination to confirm the presence of angiopatia amiloide cerebral in intracranial microcirculation.

Cerebral amyloid angiopathy-related inflammation and rapidly progressive dementia: The bleeding within the brain is usually confined to a particular lobe [5] and this is slightly different compared to brain bleeds which occur as a consequence of high blood pressure cerebtal — a more common cause of a hemorrhagic stroke or bleeding in the brain.
