Tinnitus and reduced word recognition with a bilateral inferior colliculus infarction after cerebellar arteriovenous malformation embolization

Cerebellar arteriovenous malformations (CAVMs) have increased probabilities of rupture and bleeding compared with arteriovenous malformations (AVMs) in other locations of the brain. The treatment of CAVMs includes craniotomy, endovascular treatment (EVT), radiotherapy, or a combination of multiple methods. EVT has been used in an increasing number of CAVM cases and is difficult, as the angioarchitecture of CAVMs is complex, consisting of the feeding artery, nidus, draining vein, and aneurysm on the feeding artery and in the nidus.
