title: Alternatives approaches to the sub-occipital transtentorial route for pineal tumors: How and when I do it?
abstract: Deeply located beneath the corpus callosum and surrounding by crucial veins, the pineal and tectal structures still challenge the surgeon. Either anterior or posterior, many surgical approaches have been developed to reach the pineal region. Most popular are likely the posterior sub-occipital or occipito-parietal transtentorial routes. Others, primarily transcallosal or supracerebellar, may be indicated depending of the extension of the tumors while the transcortical routes (frontal, parietal or atrial) have been almost given up. Our purpose in this article is give a practical overview of how to do and what are the respective indications of all these alternatives approaches developed for pineal tumors.
