Transpedicular Corpectomy in Minimally Invasive Surgery for Metastatic Spinal Cord Compression: A Single-Center Series.

Introduction The role of separation surgery in managing symptomatic spinal metastases has been increasing in recent years, and it represents a crucial part of the definitive management of this condition. Methods We report on a series of seven patients treated at the National Cancer Institute in Mexico using minimally invasive approaches to perform transpedicular corpectomy. The goal was to obtain a margin of tumor-free tissue, enabling the completion of oncological treatment with radiotherapy.

Rare clinical presentation of a ruptured spinal bulbomedullary arteriovenous malformation: a case report.

Introduction And Importance: Spinal arteriovenous malformations (AVMs) are a rare condition that has a high risk of bleeding and complications. The authors present the case of a spinal arteriovenous malformation in an unusual location and presentation.

Case Presentation: A 67-year-old man with subarachnoid hemorrhage due to a ruptured spinal arteriovenous malformation type IVa, with associated bulbomedullary aneurysm, which was managed conservatively due to the high risk of complications and mortality.

Demographics aspects of brain and spine metastatic melanoma. Retrospective analysis in a single third-level center.

Background: Melanoma metastases to the CNS rank third in frequency, just after lung and breast metastases. There is controversy regarding the factors predisposing to developing CNS metastases in patients with cutaneous melanoma and their survival with conventional treatments.

Methods: We carried out a retrospective analysis in a third-level hospital in Mexico to determine epidemiological aspects of melanoma metastases to the central nervous system, factors related to its appearance, clinical presentation, and survival in three treatment groups: surgery, radiotherapy, and conservative management.

Dual Microscope Indocyanine Green Video Angiography and Endoscopic Review to Treat Intracranial Aneurysm: A Review of the Literature Regarding a Case.

The use of the indocyanine green video angiography (ICG-VA) both endoscope and microscope has become popular in recent decades thanks to the safety, efficacy, and added value that they have provided for cerebrovascular surgery. The dual use of these technologies is considered complementary and has helped cerebrovascular surgeons in decision-making, especially for aneurysm clipping surgery; however, its use has been described for both aneurysm surgery, resection of arteriovenous malformations, or even for bypass surgeries. We conducted a review of the literature with the MeSH terms "microscope indocyanine green video angiography (mICG-VA)," "endoscopic review," AND/OR "intracranial aneurysm.

360-surgery for a giant cervical chordoma with involvement of the right vertebral artery.

Background: Chordomas are malignant tumors that arise from the remnants of the notochord. Complete radical resection with postoperative radiation therapy is currently considered the gold standard. Here, we performed a 360-staged approach to manage a C3-C4 chordoma that involved the right vertebral artery.

Case of anterolateral migration of herniated cervical disc fragment mimicking a spinal meningioma.

Background: Before the introduction of high-resolution MR, few disc fragments were misdiagnosed as meningiomas.

Case Description: A 63-year-old female presented with a 6-month history of mild to moderate pain in the left arm, weakness 4/5 in the left arm C5-C6 distribution, and a loss of the left biceps reflex response. Although the MR study was read as showing a C5-C6 level probable spinal meningioma, this proved to be a sequestrated disc fragment at surgery.

Histopathological Correlation (World Health Organization Classification) of Meningiomas and Their Anatomical Localization: A Multicenter Epidemiological Study in Mexico.

Objective: To determine the epidemiology of the localization and histological type of meningiomas in the Mexican population and the distribution of the different histological patterns and their relationship to tumor localization and patient demographics.

Methods: A retrospective analysis was performed in 5 hospitals in Mexico from 2009 to 2019. For qualitative variables, mean values were compared using Pearson χ test for the correlation between location and histological pattern as well as the clinical presentation and the patient's sex.

Minimally invasive management for a giant lumbar intervertebral disc herniation: A case report, and literature review.

Introduction And Importance: Low back pain and lower limb radiculopathy are some of the most common diagnoses in our neurosurgery department. Giant lumbar intervertebral disc herniation, are not a common find in our daily practice. Management for this kind of pathology is controversial.

Intracranial hypertension syndrome secondary to internal jugular vein thrombosis due to miliary cervical tuberculosis: A case report.

Background: Thrombosis of the internal jugular vein (IJV) is extremely rare, being central catheterization the most common cause. We present a case of a patient with an unusual appearance of neurological symptoms as a consequence of thrombosis of the IJV secondary to miliary tuberculosis.

Case Description: A 30-year-old woman with disseminated tuberculosis, with multiple lymphadenopathy, axillary, cervical, mesenteric, retroperitoneal, and inguinal, presented with clinical evidence of intracranial hypertension.

Ventriculopleural shunt dysfunction as the first sign of a hidden aneurysmal Subarachnoid Hemorrhage: A case report.

Introduction: Subarachnoid Hemorrhage (SAH) is caused by an aneurysmatic origin in 80% of cases. In the adult population, the risk of shunt dysfunction is about 16% in the first year, with proximal mechanical obstruction being the most frequent cause.

Case Report: An 81-year-old man with a history of shunt system placement presented among clinical data of shunt dysfunction.
