Exploration of the left half of the cerebellum and brain stem from its inferior and medial aspect
Posterior medullary velum; posterolateral fissure; peduncle of flocculus partially exposed
A portion of the tonsil has been torn away to expose the relations of the flocculus, its peduncle, the lateral recess of the ventricle and the restiform body. A segment of the posterior inferior cerebellar artery has been cut away. Its distal cut end is partially hidden by the nodulus.
