Arteriovenous malformations (AVMs) are fast-flow vascular malformations that mostly occur in the head and neck region. They are typically progressive and their spontaneous regression is almost never seen. We present a case with pulsatile tinnitus and a parapharyngeal AVM. It resolved completely after diagnostic catheter-based angiography alone.
Case Details
Disease Location
Parapharyngeal avm
Personal Characteristics
46-year-old woman. She was on oral contraceptive pills (ocps) for 16 years
Clinical Characteristics
Presented with tinnitus. Computed tomography of the head and neck revealed a left parapharyngeal arteriovenous malformation (avm). Angiography revealed an avm supplied by the distal branches of the left maxillary artery and predominantly by the artery to foramen rotundum and possibly the accessory meningeal artery.
Remission Characteristics
The tinnitus had resolved after the diagnostic angiography and she complained of heavy headedness. One month after the diagnostic angiography, another angiography showed obliteration of the avm without any evidence of the previously visualized feeding vessel
Treatment & Mechanisms
Proposed Remission Mechanisms
Diagnostic angiography might have contributed to vessel occlusion
Non-Clinical Treatment
None reported
