Intracranial bruit

A bruit invariably accompanies the pulsating proptosis of a Carotid-cavernous fistula, usually due to a head injury or due to the rupture of a carotid aneurysm in the cavernous sinus. A bruit may also be heard in the presence of a cerebral angioma but absence of a murmur does not exclude such a lesion. It has also been found out that increased row will also occur and a bruit may be heard when one is in generalized conditions such as thyrotoxicosis, severe anemia, and advanced Paget's disease of the skull.

especially with dural AVMs
