[Magnetic resonance angiography: diagnosis of pulsatile tinnitus]

Vertigo, sensorineural hearing loss and tinnitus are common symptoms in clinical otology. After exclusion of an acoustic neuroma in patients with sensorineural hearing loss and vestibular dysfunction, a vascular malformation can be responsible for pulsatile tinnitus. The two cases now reported with pulsatile tinnitus involved a dural arteriovenous malformation and a diverticulum of the jugular bulb and were diagnosed by non-invasive MR angiography. The techniques of diagnostic imaging using MR tomography, MR angiography, high-resolution computed tomography and digital subtraction angiography are demonstrated in the two cases presented.
