Pituitary adenomas constitute 25% of the primary benign neoplasms of the brain and can be functional or non-functional, or depending on their size they can be microadenomas, macroadenomas, and giant adenomas. They are mainly treated by surgery using the either transcranial or transsphenoidal approach. We show the experience in the surgical treatment of pituitary adenomas in the Guillermo Almenara National Hospital from January 2019 to May 2020.

The prevalence of valve dysfunction (VD) in pediatric centers is high. A descriptive observational study was carried out, the objective of which was to find factors: epidemiological characteristics of hydrocephalus and other derivatives of the ventricle-peritoneal shunt system (VPSS) associated with VD. We studied all the diagnoses of VD for 3 years in the Neurosurgery Service of the Baca Ortiz Pediatric Hospital, in Quito, Ecuador.

Early endovascular therapy of a ruptured giant aneurysm associated with intracerebral hematoma avoids the need for clipping of the aneurysm, thereby avoiding the need for greater brain retraction, edema, transient clipping, as well as the possibility of intraoperative rupture, thus achieving timely and adequate management of this pathology.

Cerebral aneurysms in pediatric age are rare. In early childhood, they appear before the age of 2 years and are related to a high incidence of injuries along the middle cerebral artery, in its distal part, and in the vertebrobasilar system. The etiology can be idiopathic, traumatic, and fungal. Aneurysm obliteration should be as early as possible in patients with low surgical risk.

Endovascular treatment of ruptured and non-ruptured brain aneurysms is an appropriate option in most patients. In narrow neck aneurysms, treatment with coils is sufficient, but in those with wide necks, the use of stent-assisted coils or flow diverters is necessary. Endovascular treatment of intracranial aneurysms is effective and provides complete occlusion in up to 85% of cases, however, there are cases of incomplete obliteration or recanalization that require treatment.

Tumors of the central nervous system (CNS) in children between 0 and 2 years of age are infrequent, so their diagnosis and treatment constitute an important challenge for every pediatric neurosurgical center, to which is added the comorbidities typical of this age. The objective of this study was to describe the diagnostic and therapeutic experience of a neurosurgical Department of national reference in Quito, Ecuador.

Neurosurgery as a medical discipline has always been on the cutting edge of technology and the latest advancements. It’s not a surprise why modern neurosurgeons actively utilize various social media platforms, in order to share the latest news or showcase interesting cases they face daily. From Twitter to LinkedIn neurosurgical professionals of the world share the knowledge and connect with each other in order to advance their skills to the next level.

Rosai-Dorfman disease is a pathology of histiocytic, proliferative, idiopathic and benign type characterized by sinus histiocytosis and massive lymphadenopathy. The most frequent clinical presentation is painless bilateral cervical lymphadenopathy. Extra-nodal involvement occurs in 43% of cases and central nervous system (CNS) involvement in 4%. We present a case of this rare entity.

The intracranial enterogenous cyst is a benign cystic tumor lesion of very rare frequency worldwide. These cysts can occur at any level of neuroaxis and their malignant transformation is rare. The case of a 32-year-old woman with a cystic lesion in the posterior fossa at the level of the occipitocervical junction is presented.
