Extra cranial arteriovenous malformations presenting as pulsatile tinnitus

We present two cases of extra cranial arteriovenous malformations, which presented as pulsatile tinnitus. They were originally diagnosed by clinical examination and both lesions were subsequently confirmed by angiography and their feeding vessels defined. One case was managed by surgical excision, which produced relief of symptoms. The diagnosis and management of arteriovenous malformations is discussed.
