Symptom Finder - Intracranial Bruit
INTRACRANIAL BRUIT
Intracranial bruits can be heard best over the orbits or mastoids. A list of possible causes can be developed by using the mnemonic MINTS.
M—Malformations should bring to mind arteriovenous malformations of the brain and persistent trigeminal artery.
I—Inflammatory lesions do not customarily cause intracranial bruits.
N—Neoplasm would bring to mind a cerebral angioma.
T—Trauma would suggest a traumatic caroticocavernous fistula.
S—Systemic disease such as anemia, thyrotoxicosis, and Paget disease may cause an intracranial bruit.
Bruit may be transmitted to the orbit.
Approach to the Diagnosis
If a systemic disease has been excluded by routine laboratory studies and a thyroid panel, serious investigation with an MRI, MRA, or conventional cerebral angiography should be considered. It is wise to consult a neurologist for guidance.
