Interhemispheric and quadrigeminal cysts are rare lesions, similar in their propensity to present in young babies and to be associated with other central nervous system malformations, such as corpus callosum agenesia, holoprosencephaly, encephalocele, and neuronal heterotopias. Recently endoscopy has become increasingly popular in the treatment of arachnoid cysts, but experience with cysts located in the interhemispheric fissure and in the quadrigeminal cistern is limited. ⋯ Endoscopic treatment should be considered the first-line option in the treatment of such lesions, even if some complications, such as subdural collections due to thinness of the cerebral mantle or subcutaneous CSF collections due to multifactorial associated hydrocephalus, must be expected.

Intraventricular cystic tumors constitute a surgical challenge, because of their deep location and the histologically benign nature of most of them. We aim to present concisely, yet comprehensively, the role of neuroendoscopy in the treatment of intraventricular cystic tumors. ⋯ Intraventricular endoscopy has emerged as a viable option in the treatment of intraventricular cystic tumors.

To report the efficacy, safety, and outcomes through time of the biggest series to our knowledge of pituitary surgery using transcranial, transsphenoidal, and endoscopic techniques. ⋯ The sum of this 38-year experience of managing pituitary pathology and its surgical treatment shows the importance of working together with other specialists such as endocrinologists, ophthalmologists, and radiologists. The correct treatment approach for each case must be individually selected. Transsphenoidal surgery is an effective and safe treatment for most patients with pituitary adenoma and could be considered the first-choice therapy in all cases except for prolactinomas that respond to pharmacologic therapy (dopamine agonist).

Entrapped temporal horn syndrome secondary to obstructive neoplastic lesions is most frequently treated by surgical excision of the offending lesion. Here we describe an alternate approach involving temporal horn to prepontine cistern shunting followed by radiosurgery of the offending lesion. ⋯ Trapped temporal horn syndrome secondary to obstructive neoplastic lesions can be treated by internal shunting followed by radiosurgery.
