Two rare cases of subarachnoid hemorrhage (SAH) caused by ruptured frontopolar artery aneurysms in the cingulate sulcus are presented. Both patients underwent successful surgical clipping, highlighting this uncommon cause of SAH.

Area of Science:

  • Neurosurgery
  • Neurology
  • Vascular Neurology

Background:

  • Subarachnoid hemorrhage (SAH) is a critical neurological condition.
  • Aneurysms in the cingulate sulcus, particularly of the frontopolar artery, are exceedingly rare causes of SAH.

Observation:

  • Two patients presented with symptoms of SAH.
  • Case 1 involved a 69-year-old woman with focal SAH, where an aneurysm was identified on delayed angiography.
  • Case 2 involved a 43-year-old man with diffuse SAH and multiple aneurysms, with the frontopolar artery aneurysm confirmed as the source.

Findings:

  • The study details two rare instances of ruptured frontopolar artery aneurysms in the cingulate sulcus.
  • Successful surgical clipping was achieved in both cases.
  • Delayed angiography was crucial in diagnosing the aneurysm in one of the presented cases.

Implications:

  • These cases expand the understanding of rare aneurysm locations and their association with subarachnoid hemorrhage.
  • Highlights the importance of considering less common etiologies in SAH diagnosis.
  • Reinforces the efficacy of surgical intervention for these specific aneurysms.
