Background: The perivascular spaces of the brain are also known as Virchow-Robin spaces (VRSs). Dilated Virchow-Robin spaces in the brainstem are rare and mainly cause symptoms due to obstructive hydrocephalus, less frequently because of their size, mass effect, and impact on eloquent structures.
Case Illustration: We present a patient with giant tumefactive VRS with hydrocephalus and neurological symptoms who was treated with endoscopic third ventriculostomy (ETV) followed by microscopic cyst fenestration.

Background: Pituicytoma is a rare glial neoplasm from pituicytes of the neurohypophysis or infundibulum. It occurs in the sella and suprasellar area, and it is extremely uncommon to observe intraventricular pituicytoma without affecting the infundibulum or infundibular recess.
Observations: A 69-year-old man had suffered progressive dementia for 6 months.

Department of Neurosurgery, Alicante General University Hospital, Alicante, Spain.
Introduction: Surgery of lesions in the posterior wall of the third ventricle requires great expertise due to its deep location and important surrounding structures. This region has been traditionally reached through a supracerebellar infratentorial approach, but new options have emerged, especially with the development of neuroendoscopy.
Methods: One formalin-fixed cadaver human head was dissected.
Transcallosal Retroforniceal Transchoroidal Approach: To the Posterior Third Ventricle and Beyond.
World Neurosurg

Department of Neurosurgery, University of Illinois at Chicago, Chicago, Illinois, USA. Electronic address:
Background: The transcallosal retroforniceal transchoroidal approach represents an advanced neurosurgical technique that allows access to lesions located within the posterior third ventricle and mesencephalon. It relies on a comprehensive understanding of microsurgical anatomy and embryology, integrating modern neurosurgical operative techniques to minimize retraction and injury to the normal neuronal structures.
Methods: We report the cases of 2 patients undergoing treatment via this approach, one presenting with a thalamic cavernoma and the other with cystic low-grade glioma of the midbrain.
