Audible blood flow through a cranial vessel is called intracranial bruit which makes the blood flow abnormal. Intracranial bruit may be caused due to a carotid cavernous sinus fistula or a cerebral angioma. It may also occur due to a congenital arteriovenous anomaly. A cerebral aneurysm is not very significant to cause a bruit. Severe anemia may cause intracranial bruits. All intracranial bruits should be diagnosed with MRI and angiography unless some systemic disease is found like anemia

Intracranial bruits or cervical bruits may be caused by carotid stenosis, hyperthyroidism, a venous hum, or aortic stenosis which transmits the bruit to the vessels in the neck. A carotid duplex scan and carotid angiography should be done to look for any particular carotid stenosis.

The 5 causes of intracranial bruit are – Atherosclerosis, increased blood flow, aneurysm, thrombo embolism and arterio venous misinformation.

Intracranial bruit commonly produces neuro ophthalmologic symptoms and signs. Cavernous malformations commonly cause abnormalities of supra nuclear or fascicular ocular motility. Prompt and early diagnosis of intra cranial bruit helps in proper treatment and therapy.

Intracranial bruit remains an enigma and it is not something to overshadow. It is very important to live healthy life but when one is suffering from such fatal diseases it would not be possible to stay healthy and enjoy happy healthy life. There are symptoms which on appearance mean that you have to consult to your doctor because no disease is a simple and relieving.

Intracranial bruit is commonly heard in 4 of 13 children aged between 4 months and 3 years. Intracranial bruit is a fatal disease and it has expensive treatment. If it is diagnose at time it should not be ignored because later on has to suffer a lot because of the treatment method and the charges.
