This article discusses the diagnosis, imaging workup, and management of a rare cause of pulsatile tinnitus: intraparotid arteriovenous malformation.
A single patient with a superficial temporal arteriovenous malformation diagnosed by carotid duplex causing pulsatile tinnitus that failed initial surgical management. Repeat imaging failed to identify a cause for the persistent tinnitus.
Reoperation with a parotid approach based on physical exam findings.
Removal of a more proximal arteriovenous malformation in the parotid gland resulted in long-term resolution of the patient's pulsatile tinnitus.
Physical examination is essential in the workup and management of pulsatile tinnitus. Imaging is a useful adjunct in the diagnosis of pulsatile tinnitus but should not be solely relied upon.
本文讨论搏动性耳鸣的一种罕见病因——腮腺内动静脉畸形的诊断、影像学检查及治疗。
一名颞浅动静脉畸形患者，经颈动脉双功超声诊断，因搏动性耳鸣接受初次手术治疗但未成功。重复影像学检查未能找出持续性耳鸣的病因。
根据体格检查结果采用腮腺入路再次手术。
切除腮腺内更靠近近端的动静脉畸形后，患者的搏动性耳鸣得到长期缓解。
体格检查在搏动性耳鸣的检查和治疗中至关重要。影像学检查在搏动性耳鸣的诊断中是一种有用的辅助手段，但不应完全依赖。
