Background: Granular cell tumors (GCTs) of the pituitary are rare tumors of posterior pituitary that can present as giant pituitary macroadenoma due to the slow indolent growth of the tumor. We are reporting this case due to the rarity of GCT and usually these tumors are confined to the suprasellar region since they are arising from the pituitary stalk. GCTs that attain such giant size with cavernous sinus invasion are still rarer.

Considerations for future novel human-infecting coronavirus outbreaks

Date of publication: 29-Aug-2020

Abstract

Up until, June 13, 2020, >7,500,000 cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and >400,000 deaths, across 216 countries, have been confirmed by the World Health Organization (WHO). With reference to the two previous beta-CoV outbreaks (SARS-CoV and middle east respiratory syndrome [MERS]), this paper examines the pathophysiological and clinical similarities seen across all three CoVs, with a special interest in the neuroinvasive capability and subsequent consequences for patients with primary or metastatic brain tumors. More widely, we examine the lessons learned from the management of such large-scale crises in the past, specifically looking at the South Korean experience of MERS and the subsequent shift in disaster management response to SARS-CoV-2, based on prior knowledge gained. We assess the strategies with which infection prevention and control can, or perhaps should, be implemented to best contain the spread of such viruses in the event of a further likely outbreak in the future.

Case report of hyperacute edema and cavitation following deep brain stimulation lead implantation

Albert J. Fenoy, Christopher R. Conner, Joseph S. Withrow, Aaron W. Hocher

Date of publication: 29-Aug-2020

Background: Postoperative cerebral edema around a deep brain stimulation (DBS) electrode is an uncommonly reported complication of DBS surgery. The etiology of this remains unknown, and the presentation is highly variable; however, the patients generally report a good outcome.

Long segment cervicothoracic intramedullary dermoid with concomitant conal lesion – A case report

Andrew Aranha, Pankaj Kumar, Ajay Choudhary, Purnima Paliwal

Date of publication: 29-Aug-2020

Background: Spinal dermoid cysts are benign tumors that result from congenital or acquired ectodermal inclusions. Long segment intramedullary involvement of the spinal cord is exceedingly rare, and there are only a handful of case reports found in the literature.

Glioma del nervio óptico en paciente adulto con presentación hemorrágica tratado mediante abordaje endoscópico transesfenoidal extendido

Alejandra T. Rabadán, Diego Hernández, Analía Varela, Blanca Diez, Javier Rubianes

Date of publication: 21-Aug-2020

Introducción: El glioma del nervio óptico es una entidad de muy baja incidencia en pacientes adultos, lo cual impide tener suficiente información sobre historia natural y conducta terapéutica en este grupo etario.

Comparación del tratamiento quirúrgico y endovascular de aneurismas del segmento comunicante posterior

Jose Daniel Flores-Sanchez, Giancarlo Saal, Jorge Zumaeta, Fernando Palacios, Rodolfo Rodriguez, Celia Molina

Date of publication: 21-Aug-2020

Antecedentes: Los aneurismas del segmento comunicante posterior representan aproximadamente 25% de todos los aneurismas intracraneales, y el 50% de los aneurismas de la arteria carótida interna. El objetivo fue evaluar la eficacia del tratamiento quirúrgico y endovascular en el manejo de aneurismas de esta localización.

Date of publication: 21-Aug-2020

Background: Patients with cancer are subject to all neurosurgical procedures of the general population, even if they are not directly caused by the tumor or its metastases. We sought to evaluate the impact of urgent neurosurgery on the survival of patients with cancer.

Synovial sarcoma of the spine: A case report and review of the literature

Fayez Dhafer Alshehri, Salem Khaled Baeshen, Alaa Mohammed Noor Samkari, Abeer Salim Almehdar, Ahmed Ibrahim Lary

Date of publication: 21-Aug-2020

Background: Synovial sarcoma (SS) of the spine is a rare malignant soft-tissue tumor, and there are few reported cases. The aim of this paper is to report a rare case of spinal SS involving the paraspinal muscles, and to review all such cases reported in the literature.

Burr hole microsurgery in treatment of patients with intracranial lesions: Experience of 44 clinical cases

Levan Teymurazovich Lepsveridze, Maksim Sergeevich Semenov, Armen Samvelovich Simonyan, Salome Zurabovna Pirtskhelava, Georgy Garikovich Stepanyan, Lado Kobaevich Imerlishvili

Date of publication: 21-Aug-2020

Background: Modern technical capabilities have made minimally invasive surgery increasingly popular. Small incisions can reduce surgical duration and the degree of tissue trauma, which reduces the risk of complications. Burr hole microsurgery is a relatively new minimally invasive technique used in neurosurgery. The objective of this study was to assess the feasibility and outcomes of using burr hole microsurgery for the management of intracranial lesions.

Evaluating the natural growth rate of metastatic cancer to the brain

Andrew J. Kobets, Reid Backus, Rose Fluss, Alan Lee, Patrick A. Lasala

Date of publication: 21-Aug-2020

Background: Brain metastases are becoming increasingly more prevalent as cancer patients survive longer with both improved local and systemic therapy. Little is known, however, of the natural growth rates of brain metastases. This investigation aims to ascertain this growth rate of these lesions before the initiation of any CNS- directed therapy.
