Posterior condylar canal dural arteriovenous fistula is rare, and cases of posterior condylar canal dural arteriovenous fistula directly related to trauma have been reported even less frequently. We describe a case of posterior condylar canal dural arteriovenous fistula that presented with tinnitus soon after head trauma and was successfully treated with transarterial embolization....

Signed responses from readers of the wire.
No actionable change for audiologists — this is a single case report of a rare vascular condition managed by neurosurgery; awareness that pulsatile tinnitus or unexplained audiovestibular symptoms post-trauma may warrant vascular imaging referral is the only indirect takeaway.
Rare vascular lesions near the skull base can mimic audiovestibular symptoms, and case reports like this reinforce the value of interdisciplinary referral pathways between audiology and neurovascular surgery.
- 01Single case report — lowest level of clinical evidence.
- 02Posterior condylar canal dural arteriovenous fistula treated successfully via transarterial embolization.
- 03Condition followed head trauma; indirect audiology relevance via pulsatile tinnitus or balance symptoms.
- 04Published in a neurosurgical journal; not an audiology-primary publication.
- 05Highlights importance of vascular differential diagnosis in post-traumatic audiovestibular complaints.
Transarterial embolization via the occipital artery is a viable treatment for posterior condylar canal dural arteriovenous fistula following head trauma.
