Is Cranial Bruit On Auscultation A Symptom Of Arteriovenous Malformations?

Cranial bruit on auscultation may suggest an AVM
Detailed Answer:
Hi
Welcome to the HCM
I have gone through your question and understand your concerns. An open anterior fontanella can be normal at this age. But it needs assessment if large in size and throbs uncontrollably. It's not possible to tell you the chances of it being due to any AVM or not without examination of the child.
A cranial bruit on auscultation is suggestive of arteriovenous malformations( AVM). But this needs to be assessed by pediatric neurologist on clinical examination. An ultrasound cranium may be useful initial investigation since it can be done with out any sedation.
Definitive investigation to detect AVM are MRI and cerebral angiography.
Depending on the size, location and depth of malformation, the treatment can be surgery, radiotherapy or embolisation.
I would be happy to help you with any further questions.
Take care


cranial bruit is an auscultation finding
Detailed Answer:
In this scenario, I would advice you to go with the examination finding to rule out any bruits.
If there were any such findings, your neonatologist must have told you by now. If not, then there is no need to go for investigation which can be more detrimental than useful.
Poor general health might be the cause of his large fontanella since it leads to poor bone growth.
So, I would recommend you to let him recover from other major conditions at present and don't worry about the rare possibility of AVM.
