Date of publication: 07-Jun-2018

Background:A tailor-made treatment is often required in arteriovenous malformations (AVMs) depending on the individual situation. In most cases, treatment strategy is usually determined according to the patient's Spetzler–Martin grade. However, in the present case, we were not able to treat the patient following the usual guidelines because of neurological symptoms and pregnancy.

Minimally invasive spine surgery in the pediatric and adolescent population: A case series

Richard Menger, Matthew I. Hefner, Amey R. Savardekar, Anil Nanda, Anthony Sin

Date of publication: 07-Jun-2018

Background:There is scant literature evaluating the indications, techniques, and outcomes of minimally invasive spine (MIS) surgery undertaken for pediatric and adolescent spine pathology. Our study attempts to evaluate the safe and effective use of MIS techniques in pediatric and adolescent patients and to appreciate the technical nuances of MIS surgery for this age group.

Microvascular anastomosis under 3D exoscope or endoscope magnification: A proof-of-concept study

Evgenii Belykh, Laeth George, Xiaochun Zhao, Alessandro Carotenuto, Leandro Borba Moreira, Kaan Yağmurlu, Baran Bozkurt, Vadim A. Byvaltsev, Peter Nakaji, Mark C. Preul

Date of publication: 04-Jun-2018

Background:Extracranial–intracranial bypass is a challenging procedure that requires special microsurgical skills and an operative microscope. The exoscope is a tool for neurosurgical visualization that provides view on a heads-up display similar to an endoscope, but positioned external to the operating field, like a microscope. The authors carried out a proof-of-concept study evaluating the feasibility and effectiveness of performing microvascular bypass using various new exoscopic tools.

Single-session percutaneous embolization with onyx and coils of sinus pericranii

Luana Antunes Maranha Gatto, Guilherme Naves de Lima Alves, Diego do Monte Rodrigues Seabra, Gelson Luis Koppe, Zeferino Demartini

Date of publication: 04-Jun-2018

Background:Sinus pericranii (SP) is a rare vascular malformation consisting of an abnormal communication between the extra- and the intracranial venous system. It occurs due to the adhesion of vessels without a muscular layer or a hemangioma on the outer surface of the skull through diploic vessels, communicating with an intracranial venous sinus.

Management of autonomic dysreflexia associated with Charcot spinal arthropathy in a patient with complete spinal cord injury: Case report and review of the literature

Justin L. Gibson, Shawn M. Vuong, Robert J. Bohinski

Date of publication: 29-May-2018

Background:Charcot spinal arthropathy (CSA) clearly represents a challenge in long-term spinal cord injury patients, one that can have extremely uncomfortable and potentially lethal outcomes if not managed properly.

The role of radiosurgery in the acute management of fourth ventricle compression due to brain metastases

G. Sinclair, H. Benmakhlouf, H. Martin, M. Brigui, M. Maeurer, E. Dodoo

Date of publication: 29-May-2018

Background:Approximately 20–30% of all intracranial metastases are located in the posterior fossa. The clinical evolution hinges on factors such as tumor growth dynamics, local topographic conditions, performance status, and prompt intervention. Fourth ventricle (V4) compression with secondary life-threatening obstructive hydrocephalus remains a major concern, often requiring acute surgical intervention. We have previously reported on the application of adaptive hypofractionated Gamma Knife Radiosurgery in the acute management of critically located metastases, a technique known to us as rapid rescue radiosurgery (3R). We report the results of 3R in the management of posterior fossa lesions and ensuing V4 decompression.

Giant parieto-occipital lobe pediatric gliosarcoma: Report of a rare entity and review of literature

Gautam Dutta, Robin Gupta, Manish Garg, Daljit Singh, Hukum Singh, Arvind K. Srivastava, Anita Jagetia

Date of publication: 29-May-2018

Background:Gliosarcoma is a rare high-grade malignant tumor and a variant of glioblastoma characterized by biphasic glial and mesenchymal components. Gliosarcomas occur most commonly in the fifth or sixth decade of life and have a temporal lobe predilection. Occurrence in the pediatric population is extremely rare.

Primary diffuse large B-cell lymphoma of the choroid plexus: A case report and review of the literature

Hitoshi Kayatani, Naoki Nitta, Suzuko Moritani, Kazuhiko Nozaki

Date of publication: 25-May-2018

Background:Primary lymphomas in the choroid plexus are much less frequent than primary lymphomas in the brain parenchyma.

Multiple meningiomas in two male-to-female transsexual patients with hormone replacement therapy: A report of two cases and a brief literature review

Rahul Raj, Miikka Korja, Päivi Koroknay-Pál, Mika Niemelä

Date of publication: 25-May-2018

Background:Exogenous sex hormones may play a role in meningioma development and growth. Thus, transsexual patients being on long-standing hormone replacement therapy (HRT) may be at particular risk for meningioma development and growth. Here we present two cases of two male-to-female transsexual patients taking HRT for an extended period of time with both patients requiring surgical treatment at our institution due to multiple growing meningiomas.

Intracranial complications of acute bacterial endocarditis

Burke A. Cunha, Ismail Jimada, Karishma Chawla

Date of publication: 25-May-2018

Background:Infectious endocarditis (IE) clinically manifests as either subacute bacterial endocarditis (SBE) or acute bacterial endocarditis (ABE). Neurologic manifestations are markedly different for these two entities. ABE is caused by invasive, highly virulent pathogens (e.g., Staphylococcus aureus), whereas SBE is attributed to relatively avirulent, non-invasive organisms (e.g., viridans streptococci).
