=====Splenial habenular junctional area=====
The splenial-habenular junctional area is an alternative site for neuroendoscopic fenestration to divert CSF flow into the [[quadrigeminal cistern]] in cases in which [[endoscopic third ventriculostomy]] is not amenable. In some patients with [[obstructive hydrocephalus]], the [[splenium]] of the [[corpus callosum]] can be elevated from the habenular complex. This exposes the membranous connection between the splenium and [[habenula]], which can be fenestrated to divert the CSF flow into the quadrigeminal cistern. This technique can be performed in patients in whom the [[foramen of Monro]] or the [[third ventricle]] is blocked by a lesion. 

Idris et al. present 3 complex cases that were managed by neuronavigation-guided transventricular transcavum endoscopic fenestration of the splenial-habenular junctional area. These cases may increase the knowledge and understanding of the anatomy of this region
