Interhemispheric approaches are the best way to access the midline lesions along the corpus callosum. These approaches can be used to easily access the lateral and third ventricles or lesions of the pineal region depending on tumor extension. Since most of the distal anterior cerebral artery (DACA) aneurysms are located in the rostrum part of the corpus callosum, the anterior interhemispheric approach is also the most appropriate way to reach these lesions. Posterior interhemispheric approaches provide a good anatomical corridor for splenium tumors, occipital lobe tumors, pineal region tumors, posterior falx tumors, posterior mesial temporal tumors, intraventricular trigone region tumors and the tumors of pulvinar part of the thalamus. Surgical anatomical practice on cadavers during neurosurgery training provide great benefit in preventing problems during surgery.
