Date of publication: 13-Jan-2021

Background: Injury of the internal carotid artery (ICA) during transsphenoidal surgery (TSS) is a rare but critical complication. There are several reports on endovascular treatment of ICA injury during TSS. With the recent flourishing of extended TSS, injuries to the distal arteries such as the anterior cerebral artery (ACA) are more likely to occur.

Unilateral posterior reversible encephalopathy syndrome characterized with a long and gradually exacerbating course over 3 years and that presented propofol infusion syndrome – A case report

Masahito Katsuki, Dan Ozaki, Norio Narita, Naoya Ishida, Ohmi Watanabe, Siqi Cai, Shinya Shimabukuro, Teiji Tominaga

Date of publication: 13-Jan-2021

Background: Posterior reversible encephalopathy syndrome (PRES) is characterized by acute neurological symptoms and vasogenic edema, and most patients wholly recover. We report a unilateral PRES patient characterized by a gradual onset followed by propofol infusion syndrome (PRIS) due to general anesthesia therapy.

Delayed definitive treatment of life-threatening neurosurgery patient with suspected coronavirus disease 2019 infection in the midst of pandemic: Report of two cases

Ahmad Faried, Nucki Nursjamsi Hidajat, Ali Budi Harsono, Gezy Weita Giwangkancana, Yovita Hartantri, Akhmad Imron, Muhammad Zafrullah Arifin

Date of publication: 13-Jan-2021

Background: Coronavirus disease 2019 (COVID-19) pandemic has affected global health system; in the context of the COVID-19 pandemic, both surgeon and anesthesiologist often dealt with emergency situation, optimal timing of surgery and safety protocol in hospital setting must be implemented with many facets for both patients and health-care providers.

Primary intradural/extradural Ewing’s sarcoma of the sacral spine: A case report and literature review

Daniel B Murray, Jack Horan, Alan Beausang, Mohammed Ben Husien

Date of publication: 13-Jan-2021

Background: Ewing’s sarcoma (ES) is a malignant mesenchymal tumor, most often found in the long bones, and usually affecting children and adolescents in the second decade of life. ES of the spine is a clinical rarity.

Trauma may affect vasa vasorum to promote thrombosis and enlargement of intracranial aneurysms: A case report

Mitsuhiro Anan, Yasuyuki Nagai, Takeshi Matsuda, Minoru Fujiki

Date of publication: 13-Jan-2021

Background: Thrombosed intracranial aneurysm (IA) is likely to occur in large or giant IAs. Almost all thrombosed IAs are found already in a thrombosed state, and few reports have depicted the process of thrombosis in unthrombosed aneurysm. Moreover, no reports appear to have described IA in which thrombosis accelerated after trauma.

Grisel’s syndrome in adults: A case report

Dilyan Ferdinandov, Dimo Yankov, Assen Bussarsky

Date of publication: 13-Jan-2021

Background: The non traumatic, post inflammatory atlantoaxial rotatory instability, also known as Grisel’s syndrome is a relatively rare condition usually affecting children. Adult cases are rare and even less frequently reported with separate case reports describing a single patient. Although antibiotic treatment and close neurological monitoring seem to be the gold standard of care, there is no general consensus on the optimal timing and extent of the surgical treatment.

Resolution of venous pressure gradient in a patient with idiopathic intracranial hypertension after ventriculoperitoneal shunt placement: A proof of secondary cerebral sinovenous stenosis

Thomas Buell, Dale Ding, Daniel Raper, Ching-Jen Chen, Zaid Aljuboori, Davis Taylor, Tony Wang, Natasha Ironside, Robert Starke, Kenneth Liu

Date of publication: 13-Jan-2021

Background: The relationship between idiopathic intracranial hypertension (IIH) and cerebral sinovenous stenosis (CSS) remains unclear. The effects of cerebrospinal fluid (CSF) diversion on venous sinus physiology have not been rigorously investigated. We describe the effect of ventriculoperitoneal shunt (VPS) placement on sinovenous pressures in the setting of IIH and CSS.

Osimertinib-induced rapid regression of large metastatic tumor to the pituitary in a patient with lung adenocarcinoma

Andrew K. Wong, Troy W. Close, Ricky H. Wong

Date of publication: 13-Jan-2021

Background: Metastatic nonsmall cell lung cancer (NSCLC) to the pituitary (NSCLC-PitM) is rare and often presents with visual field deficits. Surgical resection for the decompression of the optic apparatus has been the treatment of choice in such cases. Osimertinib is a third-generation tyrosine kinase inhibitor (TKI) approved for the treatment of patients with NSCLC with an epithelial growth factor receptor (EGFR) mutation though its role in the treatment of NSCLC-PitM that remains unclear. We present a case of NSCLC-PitM with optic chiasm compression and visual deficits that were successfully treated with osimertinib alone without surgical intervention.

Chemotherapy-induced changes in tumor consistency can allow gross total resection of previously unresectable brainstem pilocytic astrocytoma

Douglas J. Chung, Bilal Arif, Yazmin Odia, Vitaly Siomin

Date of publication: 13-Jan-2021

Background: Low-grade gliomas (LGG) are described by the World Health Organization as Grades I and II. Among LGGs, the most common primary brain tumor is pilocytic astrocytoma (PA) and carries an excellent prognosis when treated with complete surgical resection. Cases, in which this is not possible, are associated with less favorable outcomes and worse progression-free survival.

The most recommended neuroanatomy resources for neurosurgeons: an international survery
