Recent case reports of junctional neural tube defect (JNTD) which is a peculiar type of spinal anomaly showing the functional disconnection of the primary and secondary neural tubes has risen interest in the process of junctional neurulation (the connection between the two neural tubes) during development. This article summarizes the clinical features of the JNTD and reviews the literature on the basic research on junctional neurulation.

Traumatic brain injury (TBI) is the leading cause of death and disability in children. Survivors of severe TBI are more susceptible to functional deficits, resulting in disability, poor quality of life, cognitive decline, and mental health problems. Despite this, little is known about the pathophysiology of TBI in children and how to manage it most effectively. Internationally, efforts are being made to expand knowledge of pathophysiology and develop practical clinical treatment recommendations to improve outcomes. Here we discuss recently updated evidence and management of severe pediatric TBI.

This report introduces a simple method to visualize the captured thrombus in real-time during suction thrombectomy using "contrast-in-stasis technique". It enables visualization of the thrombus captured by a suction catheter as it is being retrieved through the tortuous course of the carotid artery eventually into the guiding catheter. It also offers visual identification of important findings such as fragmentation of thrombus into pieces or loss of thrombus during retrieval, and, therefore, helps clinicians to make further critical decisions during the procedure.

Pediatric intracranial arteriovenous malformations (AVMs) are challenging lesions managed by pediatric neurosurgeons. The high risk of hemorrhage and neurologic injury is compounded by the unique anatomy of each malformation that requires individualizing treatment options. This article reviews the current status of pediatric AVM epidemiology, pathophysiology and clinical care, with a specific focus on the rationale and methodology of surgical resection.

Objective : Helicopter ambulance transport (HAT) is a highly resource-intensive facility that is a well-established part of the trauma transport system in many developed countries. Here, we review the benefit of HAT for neurosurgical patients in Korea. Methods : This retrospective study followed neurotrauma patients who were transferred by HAT to a single emergency trauma center over a period of 2 years. The clinical benefits of HAT were measured according to the necessity of emergency surgical intervention and the differences in the time taken to transport patients by ground ambulance transport (GAT) and HAT. Results : Ninety-nine patients were transferred to a single university hospital using HAT, of whom 32 were taken to the neurosurgery department. Of these 32 patients, 10 (31.3%) needed neurosurgical intervention, 14 (43.8%) needed non-neurosurgical intervention, 3 (9.4%) required both, and 11 (34.4%) did not require any intervention. The transfer time was faster using HAT than the estimated time needed for GAT, although for a relatively close distance (<50 km) without ground obstacles (mountain or sea) HAT did not improve transfer time. The cost comparison showed that HAT was more expensive than GAT (3,292,000 vs. 84,000 KRW, p<0.001). Conclusion : In this Korean-based study, we found that HAT has a clinical benefit for neurotrauma cases involving a transfer from a distant site or an isolated area. A more precise triage for using HAT should be considered to prevent overuse of this expensive transport method.

Hypereosinophilic syndrome is a rare hematologic disorder with sustained eosinophilia. Peripheral blood eosinophilia without an underlying etiology and with organs dysfunction has been designated hypereosinophilic syndrome. We report a rare case of symptomatic spinal infiltration of eosinophils at osteolytic T5 in patient with idiopathic hypereosinophilic syndrome.

Benign osteoblastoma is an uncommon primary bone tumor, extremely rare in calvarium. We present a case of a 25-year-old female with an osteoblastoma of parietal bone which was totally resected. The authors discussed the clinical presentation, radiographic finding, differential diagnosis and management of the benign calvarial osteoblastoma with a review of the literature.

The incidence of spinal meningioma is very rare in children. A 14-year-old girl presented with right arm weakness, gait disturbance, and urinary incontinence. Cervical magnetic resonance imaging revealed an intradural extramedullary tumor dorsal to the spinal cord in the level of C1. The tumor was totally removed despite the severe cord compression. Meningotheliomatous meningioma was diagnosed after histological examination.

Cervicothoracic junction instability should be stabilized with the circumferential fusion. In addition, cervicothoracic junctional area should be examined carefully in acute traumatic injury not only to confirm hidden lesions but also to make the proper surgical plans. Here, three patients who underwent cervicothoracic arthrodesis at our institution are presented with a review of literature.

We report a rare case of tension pneumocephalus after eyebrow surgery for the treatment of a saccular aneurysm at posterior communicating artery. The patient's consciousness was suddenly aggravated due to the tension pneumocephalus on fifth postoperative day, which was treated by repairing the frontal sinus. The patient was recovered completely and uneventfully after this revision surgery.
