Surgical management of vertebral metastatic gastrointestinal stromal tumor: Case illustration, literature review, and pooled analysis
Date of publication: 15-Oct-2020
Background: Gastrointestinal stromal tumors (GISTs) very rarely metastasize to the vertebrae. Tyrosine kinase inhibitors (TKIs) confer favorable long-term survival and durable disease control for metastatic disease. Here, we reviewed a case and the literature to determine the various management options, and neurological outcomes for these patients.
Radionuclide tumor necrosis factor-alpha activity in herniated lumbar disc correlates with severe leg pain
Date of publication: 15-Oct-2020
Background: Lumbar disc herniation is often associated with an inflammatory process. In this context, inflammation has been considered a key factor in the modulation of pain. Here, we present a case of inflammatory activity directly documented in a patient with a lumbar disc herniation.
Successful mechanical thrombectomy using a combined technique for internal carotid artery occlusion with persistent primitive trigeminal artery
Date of publication: 15-Oct-2020
Background: The prevalence of persistent primitive trigeminal artery (PPTA) has been reported to be 0.1–0.6%. We report the successful recanalization of internal carotid artery (ICA) without embolization to new vascular territory (ENT) using a combined technique in a case of ICA occlusion with PPTA.
Endoscopic-assisted paramedian infratentorial supracerebellar approach for pineal cyst – How I do it Video clip
Date of publication: 15-Oct-2020
Background: The endoscopic supracerebellar-infratentorial (SCIT) approach is a viable method to access pathology of the posterior incisura, but a narrow working space and frequent instrument conflict can potentially limit its surgical efficacy. We planned an endoscopic-assisted paramedian infratentorial supracerebellar approach for pineal cyst.
Parte I: Anatomía microquirúrgica tridimensional de la ínsula
Date of publication: 15-Oct-2020
Antecedentes: El lóbulo de la ínsula, o ínsula, se encuentra oculto en la super cie lateral del cerebro. La ínsula está localizada profundamente en el surco lateral o cisura silviana, recubierta por los opérculos frontal, parietal y temporal. Estudiar la compleja anatomía del lóbulo de la ínsula, una de las regiones de mayor complejidad quirúrgica del cerebro humano, y su correlación anatómica con casos quirúrgicos.
Triplomyelia in a case of diastematomyelia: A new entity

Technical nuances of a posterior-only L5 vertebrectomy with anterior column reconstruction
Date of publication: 08-Oct-2020
Background: Burst fractures involving the L5 vertebra are quite rare . They can be managed with anterior, posterior, or combined 360 approaches. Here, we report a 25-year-old female who presented with a traumatic cauda equina syndrome attributed to an L5 burst fracture following a motor vehicle accident, and who did well after a posterior-only decompression/fusion.
Late-onset occlusion of the Monro foramina after endoscopic third ventriculostomy in adults: Case discussion and review of the literature
Date of publication: 08-Oct-2020
Background: Few cases of adult idiopathic occlusion of the foramen of Monro (AIOFM) are described in the literature. The diagnosis of AIOFM after an endoscopic procedure is even more infrequent.
Spinal cord herniation following multilevel anterior cervical discectomy and fusion: A case report and literature review
Date of publication: 08-Oct-2020
Background: Anterior cervical discectomy and fusion (ACDF) is one of the most commonly performed spinal operations. Spinal cord herniation following these procedures is rare, more typically being described as occurring posteriorly rather than following anterior corpectomy and fusion (e.g., reported in four corpectomy cases). Here, we describe a case in which spinal cord herniation was attributed to a three-level ACDF.
The relationship between vascular endothelial growth factor and histological grade in intracranial meningioma
Date of publication: 08-Oct-2020
Background: Meningioma is the most common benign intracranial neoplasm, accounting for 30% of all primary brain tumors. In 90% of cases, meningiomas are benign. Several aspects of molecular biology, including potential biomarkers, have been studied in attempts to better understand the natural history of meningiomas. Vascular endothelial growth factor (VEGF) is a biomarker responsible for inducing physiological and pathological angiogenesis. VEGF expression has been investigated as a potential predictor of several tumor aspects, including growth rate, recurrence rate, brain tissue invasion, peritumoral edema and surgical prognosis, and also as a marker of histological grade. However, there is no consensus in the literature with respect to the association between this biological factor and meningioma. We digitally analyzed immunohistochemical images using ImageJ software with the aim of correlating VEGF expression with tumor histology.
