Since January 2020, when the pathogen causing the coronavirus disease was identified in humans, the literature on coronavirus disease 2019 (COVID-19) has grown exponentially to more than 4000 publications. There is the need to provide an update for each single medical discipline, including neurosurgery, to be used by single professionals or to be distributed through the neurosurgical community and to be used by governments in designing new scenario of care. ⋯ The neurosurgical scientific community has promptly reacted to the COVID-19 outbreak by producing a growing number of documents that could serve as guidance for neurosurgeons all over the world. Neurosurgical societies will represent the key institutions for guiding the neurosurgical community to overcome the COVID-19 crisis.

Review Case Reports
Cerebellar pleomorphic xanthoastrocytoma with BRAF V600E mutation: A case report.
Pleomorphic xanthoastrocytoma (PXA) is a rare type of astrocytoma with a peak incidence from 10 to 19 years of age. PXA is found most commonly in the supratentorium. When it is present in atypical areas such as the infratentorium, it is often overlooked as a potential differential diagnosis. ⋯ To our knowledge, this is the first case of PXA in the infratentorium with BRAF V600E mutation. The case also highlights the clinical relevance of including PXA as a differential diagnosis for lesions of the infratentorium.

Double stent-assisted coiling of wide-neck bifurcation aneurysms (WNBAs) can be technically challenging with high thromboembolic rates. Single stent-assisted coiling (SSAC) decreases procedural complexity and thromboembolic risk but increases risk of coil prolapse and recanalization. In this study, we present our institution's experience with SSAC of WNBA performed via a "shouldering" and "framing" with a single Atlas stent and a spherical 3-dimensional (3D) Stryker coil. ⋯ Coil embolization performed via shouldering with a single Atlas stent and framing with a spherical 3D Stryker coil is a feasible, safe, and effective neuroendovascular treatment for WNBAs.
