Summary

An audible bruit is a rare presenting symptom of intracranial aneurysms. Surgical intervention for these aneurysms, even without hemorrhage, is recommended due to the potential risks.

Area of Science:

  • Neurology
  • Neurosurgery
  • Vascular Neurology

Background:

  • Intracranial aneurysms are abnormal bulges in brain blood vessels.
  • Bruits (abnormal sounds heard over blood vessels) are rarely associated with intracranial aneurysms.

Observation:

  • A patient with a middle cerebral artery aneurysm presented with a subjective and objective bruit.
  • The bruit resolved after surgical clipping of the aneurysm.

Findings:

  • Literature review identified 12 cases of intracranial aneurysms with associated bruits.
  • Hemorrhage (subarachnoid or cavernous sinus) was the primary presentation in 67% of reported cases.
  • The current case highlights a bruit as the presenting symptom in an asymptomatic patient.

Implications:

  • Audible bruits, though rare, warrant serious surgical consideration for intracranial aneurysms.
  • This finding suggests that bruits can indicate aneurysm presence even without overt hemorrhage.
  • Further research into the mechanisms of bruit production in aneurysms is needed.
