Pineal region

The area of the brain bounded dorsally by the splenium of the corpus callosum and the tela choroidea, ventrally by the quadrigeminal plate and midbrain tectum, rostrally by the posterior aspect of the third ventricle, and caudally by the cerebellar vermis 1).

The pineal region, also referred to as the posterior incisural space, is one of the most complex neurosurgical regions 2).
