Summary
Berry aneurysms can unexpectedly cause acute ischemic events, such as stroke, due to aneurysm thrombosis. This case series highlights an unusual presentation of intracranial aneurysms.
Area of Science:
- Neurology
- Vascular Surgery
Background:
- Intracranial aneurysms typically present with subarachnoid hemorrhage.
- Aneurysm thrombosis is an uncommon but recognized complication.
Observation:
- Four patients (1 male, 3 female; ages 38-65) presented with acute ischemic stroke.
- Neuroradiology revealed aneurysm thrombosis in three cases, with aneurysms measuring <25 mm.
- One patient had a lumbar puncture showing subarachnoid hemorrhage.
Findings:
- Aneurysm thrombosis can manifest as an acute ischemic event.
- The underlying mechanisms may involve hemodynamic or parietal changes within the aneurysm.
Implications:
- This presentation challenges the typical understanding of intracranial aneurysm natural history.
- A specific management protocol is proposed for these atypical aneurysm presentations.
- Early recognition of aneurysm thrombosis is crucial for appropriate patient management.
