Figure 2: Cerebellar arteries. (a) Superolateral view. The posteroinferior cerebellar artery originates from the posterior surface of the vertebral artery, coursing in the cerebellomedullary cistern dorsally toward the olive and cranial nerves, exiting the postolivary sulcus, below glossopharyngeal and vagus nerves and above accessory nerve. (b) Enlarged superolateral view. The anteroinferior cerebellar artery and the nerves entering the internal acoustic meatus have been divided to better demonstrate posteroinferior cerebellar artery course and relationship to the lower cranial nerves. (c) Superior view: section at the level of the cochlear nuclei and inferior cerebellar peduncle of the medulla. Medullary perforators originating from the posteroinferior cerebellar, vertebral, and basilar arteries are well demonstrated. (d) Medullary section at the level of the hypoglossal nuclei.
