Anaplastic astrocytoma (AA) or grade III is a primary brain tumor, astrocytic, malignant, and diffusely infiltrating. The survival of patients depends on several clinical and treatment factors, being this unknown in our environment. The objective of this study was to determine the survival of patients operated on for grade III astrocytoma and the impact of preoperative and postoperative prognostic factors.

Gliomas of the optic nerve, visual pathway, and hypothalamus are treated as a single entity, being considered benign neoplasms in pediatric age, grade I according to the WHO. 25% of them are confined to the optic nerve, 40-75% involve the optic chiasm, and 33-60% are posterior lesions. Most do not present symptoms, but in the case of presenting, the most frequent is loss of vision. The gold standard for diagnosis is magnetic resonance imaging (MRI) with contrast. The first line of treatment is chemotherapy, with surgery used for nerve decompression, if necessary.

Esthesioneuroblastoma, or olfactory neuroblastoma, is a rare malignant neoplasm of the sinonasal tract that originates in the olfactory neuroepithelium with neuroblastic differentiation. It occurs most frequently in the upper nasal cavity. It is a locally aggressive neoplasm and metastasizes both hematogenously and lymphatic. A multimodal approach, which can combine surgery, chemotherapy, and radiotherapy, is essential for the management of these tumors.

Los adenomas de hipófisis representan el 90% de los tumores de la región selar. El cirugía se realiza mediante la resección transesfenoidal (RTE) o transcraneal (RTC); La RTE puede ser mediante microscopía o endoscopía endonasal. La hemorragia subaracnoidea (HSA) asociada a un tumor de hipófisis es rara y puede ser: Preoperatoria, por apoplejía hipofisiaria con ruptura de aracnoides hacia las cisternas basales, Intraoperatoria, debido a una lesión vascular durante la cirugía o ruptura de un aneurisma no identificado; y Postoperatoria, debido a hemorragia del tumor residual, o sangrado de pequeños vasos adheridos a la cápsula tumoral.

Pneumocephalus or the presence of air in the cranial cavity is common after a craniotomy and in patients with traumatic brain injury; however, its spontaneous appearance is extremely rare. So far, very few cases of spontaneous intraventricular pneumocephalus have been reported. We present the case of a patient who developed spontaneous intraventricular pneumocephalus, which required a craniotomy for surgical correction.

We report the exeresis of a cerebral cavernoma, by using the extracorporeal telescope ("exoscope") operating system integrated into the Kinevo 900 microscope. The objective of this study was to evaluate the surgical potential of this novel high-speed 3D exoscope system. definition (4K-HD) for the removal of a brain cavernoma.

Neural tube defects (NTD) are congenital malformations that are caused by the lack of fusion of the neural tube during the embryonic period, exposing the nervous tissue to the outside. There are different types, and they can be cranial (anencephaly and encephalocele) and spinal (spina bifida). The encephalocele is a protrusion or herniation of the intracranial content, through the bony defect of the skull. In this article, we report the case of a patient diagnosed with occipital encephalocele, while reviewing the neurosurgical treatment performed in our hospital.

Robotic technology has helped medicine to reduce exposure time and offer greater efficiency and precision in surgical interventions. The goal of using an articulated robotic arm for X-ray (Rx) guided minimally invasive surgery and interventional assistance is to reduce direct and secondary radiation on physicians. The use of a collaborative robotic arm (COBOT) that replaces the operating arm of the surgeon-interventionist physician to avoid exposure to X-rays is described.

Nosocomial Infections (NIs) occurred in a third of the patients; increasing in those with traumatic pathology, undergoing surgery, admitted to the ICU, and prolonged hospital stay; thereby increasing mortality. It is unavoidable to consider the presence of Gram-negatives and enterobacteria when using antimicrobials in the treatment of NI in neurosurgical patients.This study shows the epidemiology of NIs inhospitalized in the Neurosurgery Service of Cayetano Heredia Hospital (HCH), between April 2020 and March 2021.
