Case ReportsCerebral hemorrhage with biopsy-proved amyloid angiopathy.
Clinical, radiological, and immunohistochemical findings in brain biopsy specimens from six patients with cerebral amyloid angiopathy-associated intracerebral hemorrhage were reviewed. Acute clinical presentations included headache, nausea and vomiting, loss of consciousness, and focal neurological deficits such as hemiplegia and blindness. Transient ischemic attacks experienced by one patient and referable to one hemisphere did not indicate impending hemorrhage in that region. ⋯ Immunoreactive senile plaques were few compared with the numbers of stained microvessels. Reactive astrocytes in some patients were labeled by both antiserum samples, suggesting uptake or production of these proteins by the astrocytes. This study demonstrates the heterogeneous clinical and radiological features of cerebral amyloid angiopathy-related brain hemorrhage and the value of anti-A4 and anti-gamma-trace immunohistochemical study of biopsy material from patients with suspected cerebral amyloid angiopathy-related intraparenchymal bleeding.
