Review Case Reports
Intracranial Rosai-Dorfman disease involving the cavernous sinus: a case report and review of the literature.
Rosai-Dorfman disease (RDD), also called sinus histiocytosis with massive lymphadenopathy, is an idiopathic, non-neoplastic, lymphoproliferative disorder. Histologically, the disease is characterized by emperipolesis and S-100 immunoreactivity. RDD usually presents with massive painless cervical lymphadenopathy, with only 5% of cases affecting the central nervous system. ⋯ Central nervous system RDD is a diagnostic challenge preoperatively depending on the radiologic findings. Immunohistochemical confirmation is indispensable for the definite diagnosis. Total resection remains the most effective treatment to date. Adjuvant treatment such as chemotherapy, radiotherapy, and steroids can be administrated in cases of incomplete resection, recurrence, or multiple foci.

Review Case Reports
Pediatric Intracranial Anaplastic Gangliogliomas: Illustrative Case and Systematic Review.
We present an illustrative case of pediatric intracranial anaplastic ganglioglioma and systematically reviewed the current reported data of anaplastic ganglioglioma in the pediatric population. ⋯ Our results contribute to our understanding of the characteristics of this rare malignant tumor and show that anaplastic ganglioglioma should be considered in the differential diagnosis of intracranial tumors in pediatric patients.

Comparative Study
Stereoscopic versus monoscopic viewing of aneurysms: experience of a single institution with a novel stereoscopic viewing system.
Stereoscopic viewing of computed tomographic angiography (CT-A) or magnetic resonance angiograms might increase the diagnostic potential of these imaging techniques. Our aim was to evaluate the benefits of a novel stereoscopic viewing system for aneurysm detection compared with standard monoscopic viewing. ⋯ Stereoscopic viewing of CT-As increases the diagnostic accuracy and represents a promising technique to reduce the need for invasive DSA.

Multicenter Study Observational Study
Intelligent Surgeon's Arm Supporting System iArmS in Microscopic Neurosurgery Utilizing Robotic Technology.
Based on our previous reports, stabilizing the surgeon's arm with an intraoperative armrest is linked to improved precision of microsurgical and endoscopic procedures. We developed the robotic intelligent surgeon's arm supporting system iArmS, which automatically follows the surgeon's arm and fixes it at an adequate position. ⋯ iArmS allows continuous precise manipulations that provide high-quality surgical results in neurosurgical techniques. Moreover, iArmS is a useful automatic tool for holding and following the surgeon's arm.

Review Case Reports
Traumatic Unilateral L3-4 Jumped Facet Treated with Open Reduction and Short Segment Fusion.
Facet dislocations, or jumped facets, are part of a spectrum of flexion-distraction spine injuries. Bilateral and unilateral facet dislocations are commonly seen in the cervical spine. Traumatic jumped facets in the lumbar spine are rare injuries, and most involve the lumbosacral junction. Lumbar facet subluxations occur commonly in young patients owing to flexion-distraction forces on the lumbar spine at the time of injury combined with ligamentous laxity that exists in young patients. ⋯ Following anatomic reduction, unilateral jumped facets can be effectively treated with instrumented stabilization. This report provides evidence for the durability of short segment arthrodesis in select cases of a rare lumbar facet subluxation.
