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.
