Tinnitus is mostly caused by vascular anomalies, one type of vascular lesions and malformations, such as abnormalities of the venous system at the base of the skull, arterial or venous malformations of the head and neck, etc. Clinically, high jugular venous bulbous aneurysms and mastoid island venous malformations are common; there are also carotid artery aneurysms and carotid artery stenosis.
