Reversible leukoencephalopathy associated with cerebral amyloid angiopathy.
The authors describe three patients with reversible leukoencephalopathy associated with cerebral amyloid angiopathy (CAA). Rapid progression of neurologic symptoms was followed by dramatic clinical and radiographic improvement. Pathologically, CAA was associated with varying degrees of inflammation ranging from none to transmural granulomatous infiltration. In the appropriate clinical context, ...
متن کاملLeukoencephalopathy in cerebral amyloid angiopathy: MR imaging in four cases.
We report four cases of biopsy proved cerebral amyloid angiopathy demonstrated by MR imaging. White matter signal hyperintensities on T2-weighted spin-echo pulse sequences were present in three patients. We believe the white matter lesions associated with cerebral amyloid angiopathy are not specific to this disorder but rather reflect hypoperfusion of distal white matter resulting from vascular...
متن کاملTeaching NeuroImages: Cerebral amyloid angiopathy-related inflammation presenting with isolated leptomeningitis.
A 69-year-old woman presented with 1 month of rapid cognitive decline preceded by 1 year of very mild memory changes. Examination showed impaired attention, logopenic aphasia, anosognosia, simultagnosia, graphesthesia, and apraxia. Neuroimaging demonstrated leptomeningeal enhancement without significant parenchymal lesions or cerebral microbleeds (figure 1). A lymphocytic pleocytosis (15 nuclea...
متن کاملCerebral amyloid angiopathy.
Brain of a 66 year old woman with a four year history of progressive dementia with episodes of encephalopathy. Opposite: Multiple small, cystic, and occasionally confluent cortical scars (arrows) were restricted to the cerebrum and were due to cerebral amyloid angiopathy. Histological examination of the cortex in the postmortem brain showed numerous neuritic plaques and neurofibrillary tangles ...
متن کاملCerebral amyloid angiopathy
Cerebral amyloid angiopathy is increasingly recognized as a major cause of hemorrhagic stroke in the elderly as well as an important contributor to the growing challenge of vascular cognitive impairment, even in cerebral amyloid angiopathy patients without hemorrhagic stroke. Among the advances highlighted in this update are: (1) the importance of sulcal bleeding events in early recurrent hemor...
