Description
<p>Post-traumatic pulsatile tinnitus is likely associated with an underlying organic disease and requires prompt and detailed evaluation. We report two cases of post-traumatic pulsatile tinnitus that led to diagnosis of intracranial arteriovenous fistulas.</p><p>Case 1: A 34-year-old woman who was admitted to our hospital following a road traffic accident was referred to our department for evaluation of right ear hemorrhage and right-sided hearing loss. She had left-sided pulsatile tinnitus during follow-up. Following neurosurgical consultation, she was diagnosed with a traumatic internal carotid-cavernous sinus fistula; however, the patient’s symptoms disappeared after transvenous embolization.</p><p>Case 2: A 47-year-old man who was admitted to another hospital after a road traffic accident was referred to our department for evaluation of left-sided ossicular dissection. He developed left-sided pulsatile tinnitus after he underwent left tympanoplasty. Following neurosurgical consultation, he was diagnosed with a dural arteriovenous fistula; however, the patient’s symptoms disappeared after carotid artery embolization.</p><p>Approximately 20% of patients with intracranial arteriovenous fistula present with pulsatile tinnitus as the initial symptom. Therefore, it is important to consider the possibility of a vascular origin of tinnitus in patients who present with post-traumatic pulsatile tinnitus. Detailed examination, including evaluation for vascular sounds and interdepartmental collaboration are warranted in such cases.</p>
