Comparative StudyComparative anatomical analysis of the transcallosal-transchoroidal and transcallosal-transforniceal-transchoroidal approaches to the third ventricle.
OBJECTIVE Access to the third ventricle is a veritable challenge to neurosurgeons. In this context, anatomical and morphometric studies are useful for establishing the limitations and advantages of a particular surgical approach. The transchoroidal approach is versatile and provides adequate exposure of the middle and posterior regions of the third ventricle. ⋯ There was no difference between approaches in the exposure of the structures of the middle and posterior region. CONCLUSIONS The transforniceal-transchoroidal approach provides greater surgical exposure of the third ventricle anterior region than that offered by the transchoroidal approach. In the population studied, morphometric analysis established mean values for anatomical structures common to both approaches.

Review Comparative Study
Effectiveness of intraventricular endoscopic lamina terminalis fenestration in comparison with standard ETV: a systematic review of the Literature.
Endoscopic third ventriculostomy is a consolidated technique for the treatment of hydrocephalus. Despite its effectiveness and feasibility, several technical limitations about its use in certain situations have been described. Lamina terminalis-endoscopic third ventriculostomy (LT-ETV) has been proposed as an alternative technique. Authors systematically reviewed the literature in order to define the effectiveness and limits in comparison with standard ETV. ⋯ LT-ETV can be considered a successful technical option when standard ETV cannot be performed, although more complex cerebrovascular anatomy is involved. Therefore we suggest that lateral terminalis fenestration is a valid technical option in experienced hands.

Third ventricular cerebrospinal fluid (CSF) cysts of thalamic origin are rare. The objective of this study is to review their possible pathogenesis, clinical presentation, and management strategies with a case series describing management via an endoscopic approach with fenestration using a single burr-hole technique. ⋯ Third ventricular CSF cysts of thalamic origin most commonly present with hydrocephalus. They can be safely definitively treated via endoscopic fenestration to the CSF circulation using a single burr-hole technique. Long-term follow-up shows lasting improvement in symptoms without reaccumulation of the cyst.

Case Reports
Obstructive hydrocephalus secondary to enlarged Virchow-Robin spaces: A rare cause of pulsatile tinnitus.
Obstructive hydrocephalus secondary to enlarged Virchow-Robin Spaces (VRS) is a rare entity, with only a few cases reported in the literature. Presenting symptoms vary widely from headaches to dizziness. ⋯ This is the first case of obstructive hydrocephalus secondary to enlarged VRS, presenting with pulsatile tinnitus.

Supraorbital subfrontal trans-laminar endoscope-assisted approach for tumors of the posterior third ventricle.
Different surgical approaches have been developed for dealing with third ventricle lesions, all aimed at obtaining a safe removal minimizing brain manipulation. The supraorbital subfrontal trans-lamina terminalis route, commonly employed only for the anterior third ventricle, could represent, in selected cases with endoscopic assistance, an alternative approach to posterior third ventricular lesions. ⋯ The supraorbital subfrontal trans-laminar endoscope-assisted approach may provide, in selected cases, an efficient and safe route for dealing with posterior third ventricular tumors.
