The Posterior inferior aspect of the cerebellum and brain stem
Course of posterior inferior cerebellar artery
On the right side the tonsil has been removed. The restiform body and brachium pontis have also been cut away. The passage of the trunk of the posterior inferior cerebellar artery between the uvula (of the vermis) and the tonsil is demonstrated. The tela chorioidea of the fourth ventricle is in close relation to the artery from which branches pass to the choroid plexus. This dissection reveals the nidus avis cerebelli.
