Abstract:
Cerebral amyloid angiopathy is a clinicopathological disorder characterised by vascular amyloid deposition initially in leptomeningeal and neocortical vessels, and later affecting cortical and subcortical regions. The presence of amyloid within the walls of these vessels leads to a propensity for primary intracerebral haemorrhage. We report the unusual case of a 77-year-old female who presented to our emergency department with sudden onset isolated hypoaesthesia and right upper limb monoplegia. A CT scan demonstrated a peripheral acute haematoma involving the left perirolandic cortices. Subsequent magnetic resonance imaging demonstrated previous superficial haemorrhagic events. One week following discharge the patient re-attended with multiple short-lived episodes of aphasia and jerking of the right upper limb. Further imaging demonstrated oedematous changes around the previous haemorrhagic insult. Cerebral amyloid angiopathy is an overlooked cause of intracerebral haemorrhage; the isolated nature of the neurological deficit in this case illustrates the many guises in which it can present.
Insights
Cerebral amyloid angiopathy, a condition causing amyloid buildup in brain vessels, can lead to intracerebral hemorrhage. This case highlights its varied presentations, even with isolated neurological deficits.
Area of Science:
- Neurology
- Pathology
- Radiology
Background:
- Cerebral amyloid angiopathy (CAA) involves amyloid deposition in cerebral vasculature.
- This deposition increases the risk of primary intracerebral hemorrhage.
- CAA is often an underdiagnosed cause of stroke-like symptoms.
Purpose of the Study:
- To report an unusual case of cerebral amyloid angiopathy.
- To illustrate the diverse clinical presentations of CAA.
- To emphasize CAA as a differential diagnosis for intracerebral hemorrhage.
Main Methods:
- Case report of a 77-year-old female patient.
- Initial presentation with acute neurological deficits (hypoesthesia, monoplegia).
- Diagnostic imaging including CT and MRI to identify hemorrhage and edema.
Main Results:
- CT revealed an acute peripheral hematoma in the left perirolandic cortex.
- MRI showed evidence of prior superficial hemorrhagic events.
- Patient experienced recurrent episodes of aphasia and limb jerking, with associated edema on imaging.
Conclusions:
- Cerebral amyloid angiopathy can present with isolated neurological deficits.
- The varied manifestations underscore the importance of considering CAA in intracerebral hemorrhage cases.
- Prompt diagnosis and management are crucial for patients with CAA-related events.
