Solitary spinal epidural cavernous angiomas are rare vascular malformations. Surgical excision is the treatment of choice, as these lesions tend to grow or bleed at some point. In this 3-dimensional, narrated video, we present the case of a 61-year-old male who presented with progressive pain in the right paravertebral region secondary to an epidural cavernous angioma located at the T6/T7 level. Under intraoperative neurophysiological monitoring, a laminectomy between T5 and T7 was performed. A reddish, well delimited, and highly vascularized epidural mass was identified and dissected from the adjacent dura and nerve root, and an en bloc total resection was achieved...

Ependymoma accounts for 3-9% of all neuroepithelial tumors. The giant cell ependymoma is a rare and distinct variant, of which only twenty-two cases have been described in literature. Starting from 2007, the WHO acknowledged this rare subtype. The cytological features of GCE are the presence of pleomorphic giant cells with several cellular atypias, which at intra-operative frozen diagnosis may appear to be high-grade glial lesions. Despite its apparently malignant histology, GCE seems to be a neoplasm with a relatively good prognosis...

BACKGROUND: Intramedullary (IM) schwannomas are rare entities representing the 0.3-1% of intramedullary tumors and 1.1% of spinal schwannomas. Beside many theories proposed, their rare occurrence might be related to the absence of Schwann cells into the spinal cord. Pediatric IM schwannomas are uncommon and in absence of neurofibromatosis (NF) they are extremely rare. To date, very few cases have been reported in the literature. CASE DESCRIPTION: We describe the case of a 8 year-old female affected by a progressive paraparesis...

Intraoperative monitoring (IOM) utilizes electrophysiological techniques as a surrogate test and evaluation of nervous function while a patient is under general anesthesia. They are increasingly used for procedures, both surgical and endovascular, to avoid injury during an operation, examine neurological tissue to guide the surgery, or to test electrophysiological function to allow for more complete resection or corrections. The application of IOM during pediatric brain tumor resections encompasses a unique set of technical issues...

OBJECTIVE: Cochlear implants are generally considered a contraindication for any procedure requiring electrical stimulation near the implant. We present a case of a patient undergoing intraoperative transcranial electrical motor-evoked potential monitoring with a cochlear implant without adverse outcomes. PATIENT: A 12-year-old girl with a history of VACTERL presented with worsening congenital kyphosis and bilateral severe-to-profound hearing loss. Since age 7 the patient used a cochlear implant in the right ear and hearing aid in the left ear...

BACKGROUND: A new method in brainstem surgery, neuronavigation (NN)-guided corticospinal tract (CST) mapping, was used in a retrospective study of patients undergoing brainstem tumor surgery. METHODS: We studied 40 patients with a brainstem tumor who were enrolled in this study. Patients whose worst preoperative muscle strength of the four limbs was greater than three levels from normal on the Lovett scale were divided into two groups: a treatment group of 21 patients that included NN-guided CST mapping and routine intraoperative neurophysiology monitoring (IONM), and a control group of 19 patients that included routine NN and routine IONM...

Treatment of tumor-related epilepsy (TRE), especially for tumors near critical areas, requires surgeons to strike a balance between the epileptic benefit and functional outcome after surgery. Here, we present a case in which multimodal evaluation facilitated the achievement of such surgical balance. Informed patient consent was obtained. A 17-yr-old female presented with seizure attacks for 2 yr. Magnetic resonance imaging (MRI) revealed a right parietal mass lesion with hypointense signal on T1W imaging, hyperintense signal on T2W imaging, and homogeneous enhancement...

OBJECTIVE: High-field intraoperative MR (ioMRI) has become increasingly available in neurosurgery centers. There is little experience with the combination of ioMRI with intraoperative neurophysiological neuromonitoring (IONM). We provide a first series of pediatric patients undergoing brain tumor surgery with 3T ioMRI and IONM. METHODS: We conducted a pilot study were we included all consecutive children operated for brain tumors between October 2013 and April 2016 where concomitant ioMRI and somatosensory evoked potentials (SEP) and motor evoked potentials (MEP) were used...

BACKGROUND: Despite the extensive use of intraoperative neurophysiological monitoring (IONM) in spinal procedures, there is no standard guideline for what types of IONM tests should be monitored during lumbar procedures with instrumentation. Moreover, the efficacy of IONM during transforaminal lumbar interbody fusion (TLIF) surgery in detecting postoperative neurological deficits has not been well described. OBJECTIVE: To analyze waveform changes from individual IONM tests (somatosensory evoked potentials [SSEP], motor evoked potentials [MEP], and electromyography [EMG]) during TLIF and compare the sensitivity and specificity of these tests in order to determine the best combination to detect postoperative neurological deficits...

Laminoplasty, frequently performed in patients with cervical myelopathy, is safe and provides relatively good results. However, motor palsy of the upper extremities, which occurs after decompression surgery for cervical myelopathy, often reduces muscle strength of the deltoid muscle, mainly in the C5 myotome. The aim of this study was to investigate prospectively whether postoperative deltoid weakness (DW) can be predicted by performing intraoperative neurophysiological monitoring (IONM) during cervical laminoplasty and to clarify whether it is possible to prevent palsy using IONM...

Background and Aims: Intraoperative neurophysiological monitoring (IONM) is the standard of care during many spinal, vascular, and intracranial surgeries. High-quality perioperative care requires the communication and cooperation of several multidisciplinary teams. One of these multidisciplinary services is intraoperative neuromonitoring (IONM), while other teams represent anesthesia and surgery. Few studies have investigated the IONM team's objective communication with anesthesia providers...

INTRODUCTION: Pudendal nerve entrapment syndrome (PNE) is characterised by the presence of neuropathic pain in the pudendal nerve (PN) territory, associated or not with urinary, defecatory and sexual disorders. Surgical PN decompression is an effective and safe alternative for cases when conservative treatment fails. The aim of this study is to describe the first robot-assisted pudendal neurolysis procedure performed in our country. MATERIAL AND METHODS: We describe step by step the technique of robot-assisted laparoscopic neurolysis of the left PN performed with intraoperative neurophysiological monitoring on a 60-year-old patient diagnosed with left PNE...

BACKGROUND CONTEXT: Intraoperative neurophysiological monitoring (IONM) has gained rather widespread acceptance as a method to mitigate risk to the lumbar plexus during lateral lumbar interbody fusion (LLIF) surgery. The most common approach to IONM involves using only electromyography (EMG) monitoring, and the rate of postoperative deficit remains unacceptably high. Other test modalities, such as transcranial electric motor-evoked potentials (tcMEPs) and somatosensory-evoked potentials, may be more suitable for monitoring neural integrity, but they have not been widely adopted during LLIF...
