Objective: We aimed to demonstrate the differences between grade I and II (OMS classification) of intracranial meningiomas. We evaluate their location, Simpson resection grade, re-operations rate, adjuvant treatment and patient outcomes. Methods: We conduct a retrospective review of Sixty- three clinical records of patients who were diagnosed with meningiomas grade I and II (OMS) between 2009-2015 and received surgical treatment at our Hospital. We evaluated different variables such as age, sex, histological type, Simpson grade resection, location, symptoms, radiotherapy, follow-up, mortality rate and patient outcome...

Objective: Compare the number of recurrences in patients with WHO Grade I meningiomas that underwent microsurgical resection. Introduction: In 1957 Simpson established five grades for surgical resection for intracranial meningiomas and recurrence rate. He thought that an aggressive removal of these tumors with dura and bone was necessary to cure them. Development of new diagnostic methods, advances in anatomopathology and microsurgical technique lead us to question if this scale has a value nowadays...

Background: While craniopharyngiomas (CPs) are the most common cystic suprasellar lesions in adults, cavernous malformations (CMs) only exceptionally occur in this location and are seldom considered in the differential diagnosis of such lesions. However, unlike CPs, suprasellar CMs are not typically approached via an endoscopic endonasal approach. Case Description: We present a unique clinical case of suprasellar and third ventricular CM mimicking a CP, posing a major decision-making dilemma at the levels of both preoperative diagnosis and surgical planning...

Victor Awuor, Christopher E Stewart, Albert Camma, Julie Renner, J M Tongson
Background: Chordomas must be considered among the differential diagnoses for extradural spinal tumors, especially involving the clival or sacrococcygeal regions. They are often locally invasive and destructive to the osseous structures from which they arise, but rarely extend intradurally. Here, we report a unique chordoma that was intradural and spanned nearly four subaxial cervical vertebral levels. Case Description: We report the case of an atypical intradural chordoma that spanned four subaxial levels of the cervical spine in an 81-year-old female...

Background: To report our experience of infections in deep brain stimulation (DBS) surgeries comparing shaving versus no shaving of cranial hair. Nonshaving is strongly preferred by patients due to aesthetic and psychological factors. Methods: This study is a prospective follow-up of the infection rate in 43 nonshaven DBS cases between April 2014 and December 2015 compared to our former infection rate with shaving in our center. Minimum follow-up was 6 months. All patients, except 7 epilepsy patients, received implantation of the electrodes together with the extension cables and internal pulse generator in one session...

Background: Follicular dendritic cell (FDC) sarcoma is an extremely rare neoplasm, which has only been reported once in the literature with an intracranial occurrence. Neither hemorrhagic presentation of an intracranial instance of FDC sarcoma nor its rapid recurrence has yet been published in the literature. Case Description: We report the case of a 61-year-old female who presented with confusion and headaches secondary to a right frontal hemorrhagic lesion, and her subsequent presentations for recurrence of the lesion and finding of a new intracranial lesion...

EDITORIAL
Nancy E Epstein
Background: Lumbar surgery for spinal stenosis is the most common spine operation being performed in older patients. Nevertheless, every time we want to schedule surgery, we confront the insurance industry. More often than not they demand patients first undergo epidural steroid injections (ESI); clearly they are not aware of ESI's lack of long-term efficacy. Who put these insurance companies in charge anyway? We did. How? Through performing too many unnecessary or overly extensive spinal operations (e...

Nancy E Epstein, Renee D Hollingsworth
Background: In the lumbar spine, degenerative spondylolisthesis or degenerative (not traumatic) slippage of one vertebral body over another is divided into 4 grades - grade I (25%), grade II (50%), grade III (75%), and grade IV (100%). Dynamic X-rays, magnetic resonance (MR), and computed tomography (CT) scans document the slip secondary to arthritic changes of the facet joint plus stenosis, ossification of the yellow ligament, disc herniations, and synovial cysts. MR best demonstrates soft tissue pathology whereas CT better delineates ossific/calcified disease...

Background: Extradural hemangiomas are rare, have varied and challenging clinical presentations, and require special considerations from the management point of view. Case Description: A 70-year-old female presented with back pain that was ultimately attributed to a thoracolumbar extra-dural "dumbbell" hemangioma. Following surgical resection, the patient did well. Conclusion: Extradural hemangiomas may present as spinal extradural soft tissue masses that must be differentiated from dumbbell neurofibroma...

Background: Histologic variants of conventional glioblastoma are rare clinical entities. In recent years, an aggressive variant termed malignant glioma with primitive neuroectodermal tumor components (MG-PNET) has been described in adults. In addition to the rarity of supratentorial primitive neuroectdoermal tumors (sPNET) in adults, MG-PNET can present with unique radiographic features. Case Description: We report the case of a 42-year-old male who presented with headaches and vision changes...

Background: Mucoceles are epithelial lined sacs that contain mucous. Eventually, they can be infected and so called mucopyoceles, which are usually slow growing lesions with common bone destruction located in the facial sinus. Mucoceles show multivariate etiology and occur between the fourth and seventh decade of life. Case Description: Patient, 55-year-old, female, was referred unconscious with Cushing's triad to our department; she had fever since four days. The findings of skull computer tomography highlighted a large bifrontal lesion with an invasion of the rear wall of the frontal sinus, compression of the frontal lobes, and midline deviation...

BACKGROUND: The preferred treatment for intracranial hemangioblastomas is surgical resection with or without preoperative embolization, however, embolization remains controversial due to risks such as distal tip entrapment, vascular injury during navigation, and embolic agent migration. CASE DESCRIPTION: A 54-year-old woman was admitted for surgical resection and preoperative embolization of a cerebellar hemangioblastoma. Although experience using Onyx with detachable and nondetachable tip microcatheters has been well reported in a variety of clinical circumstances, we describe the first case of a presurgical embolization of an intra-axial tumor using a second-generation detachable-tip microcatheter and a nonadhesive liquid embolic agent...
