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.

The minipterional interfascial approach has been used in the clipping of aneurysms of the anterior circulation, the middle cerebral artery, the posterior communicating, the anterior communicating, the choroid segment and the ophthalmic; however, the use of this approach in bifurcation aneurysms has not been extensively described. We present a case using this promising technique.

The Minipterional craniotomy is reliable, less invasive, it maintains the advantages of the pterional approach but avoids greater exposure of the parenchyma and tissue manipulation. Aneurysms of the anterior circulation, ruptured and unruptured, can be treated safely and effectively with limited bone extraction, good cosmetic results and good temporomandibular function.

Endoscopic aqueductoplasty with stent placement in the Silvio aqueduct is an effective measure in cases of isolated cyst in the fourth ventricle, achieving good clinical and imaging evolution compared to other therapeutic options. We present the case of a 34-year-old patient with a history of neurocysticercosis who received antiparasitic treatment and the placement of a DVP, presenting multiple dysfunction with severe dilatation of the IV ventricle.
