Multicenter Study
Syrinx Secondary to Chiari-like Tonsillar Herniation in Spontaneous Intracranial Hypotension.
Syrinx development in patients with spontaneous intracranial hypotension (SIH) has rarely been described. To better understand this entity, we compared the clinical and radiographic findings in a series of patients with SIH and acquired Chiari-like tonsillar herniation with and without syrinx formation. ⋯ Our results have shown that SIH can be an underrecognized cause of syrinx with key differences in body habitus and obex displacement compared with SIH without syrinx. In patients with tonsillar herniation into the foramen magnum associated with syrinx, the presence of SIH should be considered to avoid unnecessary foramen magnum decompression, even in those with a normal opening pressure.

For most of the international community outside the epicenter, coronavirus disease 2019 (COVID-19) containment is normalizing, and daily medical practice runs parallel to preventing and treating COVID-19. This experience of simultaneously conducting emergent surgery and infection control for COVID-19 disease is useful outside the epicenter during the pandemic. ⋯ Rescuing patients with SAH and containment of COVID-19 benefit from joint prevention and control, a centralized system of equipment distribution and personnel assignment, and quick workflow establishment.

The current pandemic crisis, caused by a novel human coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), has forced a dramatic change in our society. A key portion of the medical work force on the frontline is composed of resident physicians. Thus, it becomes imperative to create an adequate and effective action plan to restructure this valuable human resource amid the SARS-CoV2 pandemic. We sought to describe a comprehensive approach taken by a Neurosurgery Department in quaternary care academic institution in the United States of America amid the SARS-CoV2 pandemic focused in resident training and support. ⋯ The SARS-CoV2 pandemic constitutes a global health emergency full of uncertainty. Treatment, scope, duration, and economic burden forced a major restructuring of our medical practice. In this regard, academic institutions must direct efforts to diminish further negative impact in the training and education of the upcoming generation of physicians, including those currently in medical school. Perhaps the only silver lining in this terrible disruption will be greater appreciation of the role of current health care providers and educators, whose contributions to our society are often neglected or unrecognized.

Comparative Study
Outcome of microsurgical clipping for multiple vs single intracranial aneurysms: A single institutional retrospective comparative cohort study.
To evaluate the results of microsurgical clipping for single intracranial aneurysm (SIA) and multiple intracranial aneurysms (MIA) and compare the outcomes. ⋯ Comparable clinical outcomes and high rates of complete aneurysm occlusion following microsurgical clipping can be expected in patients with SIA and patients with MIA.

Extent of resection (EOR) constitutes a crucial factor for patient prognosis in surgery of brain metastases (BMs). According to early studies using postoperative magnetic resonance imaging (MRI), an unexpected residual tumor was not uncommon. Knowledge of potential risk factors for incomplete BM resection would be of major importance to optimize surgical strategies. The aim of this study was to evaluate EOR in a large cohort and analyze potential risk factors for incomplete BM resection. ⋯ Our data indicate that postoperative MRI is able to detect a high portion of unexpected residual tumors after surgery of BMs. Preoperative tumor volume in particular represents an important risk factor for incomplete resection, and hence neurosurgeons should pay special attention to avoid residual tumor tissue.
