====== 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.
