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.

Pituitary abscess is an intrasellar infection that generates a clinical picture like any pituitary tumor. Its origin can be of hematogenous origin or by infection of a nearby site or pre-existing lesion. We present the case of a 38-year-old male patient with progressive headache, vomiting and visual impairment is presented. It was evaluated with magnetic resonance of the sellar region. Transsphenoidal surgery was performed and the infusion of intravenous antibiotic therapy continued.

Microsurgery has been the gold standard for the treatment of arteriovenous malformations (AVM), however, endovascular therapy has emerged as an option in recent years. We present the case of a previously healthy 45-year-old woman that presented with a ruptured AVM treated successfully with curative embolization.

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. 

Endovascular treatment of non-ruptured intracranial aneurysms with flow diverter devices is a technique that currently has many indications for its use. We present a retrospective review of consecutive cases treated with flow diverters at our institution. Since October 2012 to April 2017, twenty-one patients were treated with a total of 29 non-ruptured aneurysms.

Dural arteriovenous fistulas (DAVF) are vascular lesions that require a high suspicious index for its diagnosis, because of their wide variety of clinical manifestations, moreover, invasive procedures such as digital subtraction angiogram (DSA) is the gold standard and is required for its diagnostic confirmation.

Craniocervical arteriovenous fistulas (AVF) are rare entities. A high index of suspicious is required for its diagnosis. Surgery, embolization or both are available treatments. We present the case of a young woman who presented with syncope. Additional studies revealed the presence of a craniocervical junction AVF.

Arteriovenous malformations (AVM) are typically treated by arterial approach. In selected cases, venous embolization is an option with good results. We present the case of a ruptured thalamic arteriovenous malformation treated successfully with transvenous embolization using Onyx, achieving complete obliteration of the nidus.

Cerebral aneurysms are formed due to a weakness in the arterial wall, this cause a dilation and the subsequent risk of rupture, conditioning subarachnoid hemorrhage, being one of the causes of cerebrovascular disease with higher risk of morbidity or death. We presented the first brain revascularization microsurgery for the treatment of a complex cerebral aneurysm performed at the Dos de Mayo National Hospital.
