Abstract Ventral spinal tumors are surgically challenging because the tumor resection should minimize spinal cord and nerve root manipulation to minimize morbidity, while providing access to a complete tumor resection. The CO2 laser has been useful in resection of central nervous system tumors, but little is described about the method used to resect spinal tumors.1 This video demonstrates the removal of a ventral cervical spinal meningioma using the CO2 laser. A 62-yr-old man presented with progressive paresthesias, gait instability, and urinary frequency. A 1-cm intradural extramedullary mass at C5 showed severe spinal cord compression. Patient consent was obtained prior to performing the procedure. A posterior lateral approach is shown, with a bone removal corridor created at C5 for accessing the tumor ventrally. A right-sided facetectomy and pediculectomy at C5 were performed being flush with the posterior vertebral body. A dural opening positioned laterally provided a working corridor between C5 and C6 nerve rootlets. Lateral portions of tumor were excised in wedge-shaped slices starting laterally and working medially. These slices created a successive and enlarging space to safely allow piecemeal tumor dissection and removal, while limiting retraction upon the spinal cord. The CO2 laser was used to cauterize the tumor capsule, create wedge resections of tumor, and coagulate the final dural attachment. The pathology was a meningioma WHO Grade I. The patient did well, with resolution of parasthesias and ataxia. The CO2 laser technique allowed for limited spinal cord retraction throughout the tumor resection and gross total resection of the tumor was achieved.

Abstract This 3-dimensional operative video illustrates resection of 2 cervical spine schwannomas in a 19-yr-old female with neurofibromatosis type 2. The patient presented with lower extremity hyperreflexity and hypertonicity. Magnetic resonance imaging (MRI) demonstrated 2 contrast-enhancing intradural extramedullary cervical spine lesions causing spinal cord compression at C4 and C5. The patient underwent a posterior cervical laminoplasty with a midline dural opening for tumor resection. Curvilinear spine cord compression is demonstrated in the operative video. After meticulous dissection, the tumors were resected without complication. The dural closure was performed in watertight fashion followed by laminoplasty using osteoplastic titanium miniplates and screws. Postoperative MRI demonstrated gross total resection with excellent decompression of the spinal cord. The postoperative course was uneventful. The natural history of this disease, treatment options, and potential complications are discussed.

OBJECTIVE Resection significantly improves the clinical symptoms and functional outcomes of patients with intradural extramedullary tumors. However, patient quality of life following resection has not been adequately investigated. The aim in this retrospective analysis of prospectively collected quality of life outcomes is to analyze the efficacy of resection of intradural extramedullary spinal tumors in terms of quality of life markers. METHODS A retrospective review of a single institutional neurosurgical administrative database was conducted to analyze clinical data. The Oswestry Disability Index (ODI), visual analog scale (VAS) for pain, and the EQ-5D-3 L descriptive system were used to analyze quality of life preoperatively, less than 1 month postoperatively, 1–3 months postoperatively, 3–12 months postoperatively, and more than 12 months postoperatively. RESULTS The ODI scores increased perioperatively at the < 1-month follow-up from 36 preoperatively to 47. Relative to preoperative values, the ODI score decreased significantly at 1–3, 3–12, and > 12 months to 23, 17, and 20, respectively. VAS scores significantly decreased from 6.1 to 3.5, 2.4, 2.0, and 2.9 at the < 1-month, 1- to 3-, 3- to 12-, and > 12-month follow-ups, respectively. EQ-5D mobility significantly worsened at the < 1-month follow-up but improved at the 3- to 12-and > 12-month follow-ups. EQ-5D self-care significantly worsened at the < 1-month follow-up but significantly improved by the 3- to 12-month follow-up. EQ-5D usual activities improved at the 1- to 3-, 3- to 12-, and > 12-month follow-ups. EQ-5D pain and discomfort significantly improved at all follow-up points. EQ-5D anxiety and depression significantly improved at 1- to 3-month and 3- to 12-month follow-ups. CONCLUSIONS Resection of intradural extramedullary spine tumors appears to significantly improve patient quality of life by decreasing patient disability and pain and by improving each of the EQ-5D domains.

Abstract Intradural extramedullary spinal tumors were historically managed through traditional midline approaches. Although conventional laminectomy or laminoplasty provides a wide tumor and spinal cord exposure, they may cause prolonged postoperative neck pain and late kyphosis deformity. Minimally invasive ipsilateral hemilaminectomy preserves midline structures, reduces the paraspinal muscle disruption, and could avoid postoperative kyphosis deformity. A safe tumor resection through this approach could be complicated in large sized or anteromedullary located lesions. We present a surgical video of C3 antero located meningioma removed en bloc through a minimally invasive approach. The patient signed a written consent to publish video, recording, photograph, image, illustration, and/or information about him.

Abstract Purpose To study the demography, incidence, symptoms, histopathology, postoperative complications and recovery in operated patients of spinal tumor. Overview of Literature Primary spinal cord tumors (SCT) are an uncommon entity. According to their location, spinal tumors are conveniently classified as extradural (ED) and intradural (ID), although some can be both inside and outside the dura. ID tumors can be intradural extramedullary (IDEM) or intramedullary SCT (IMSCT). Methods This is a retrospective study of 122 patients with spinal tumors who were surgically treated at the department of neurosurgery from 2014 to 2019 over a period of 5 years. Study Design This is a retrospective study. Results Out of 122 patients, there were 19 patients with ED tumor, 73 had IDEM, and 30 had IMSCT. As many as 73 patients were males and the rest of the 49 patients were females. Mean age at time of surgery was 40.79 years. The thoracic region of spinal canal was most frequently involved (64; 52.4%). The common clinical symptom was motor weakness (90 cases; 73.77%). Majority of the patients had symptoms for duration of 6 to 12 months. Schwannomas were the most common tumor among IDEM and extradural location. Ependymomas were the most common type in IMSCT. We observed significant improvement in most of our cases. Four patients deteriorated at 3 months follow- up. Conclusions There was a higher male:female ratio for all spinal cord tumors except meningiomas. There was also a higher proportion of nerve sheath tumors, and a lower proportion of meningiomas and neuroepithelial tumors. These results are similar to other studies from Asian countries.

Introduction: The problem of diagnostics and treatment of oncological diseases is one of the most urgent challenges of the public health system. Despite successful achievements over the past years, surgical treatment of spinal tumors is becoming more demanded due to the increasing number of cases with complexities and long duration of the disease. The research found out developing compression of the spinal cord at 10% of patients with spinal spread. Still, the patients suffering spinal tumors are associated with high mortality rates. Aim: To analyze the results of clinical treatment of spinal tumors at patients who have received specialized orthopedic aid. Methods and materials: From 2014 to 2019, patients with spinal neoformations (N=240) received surgical treatment at Traumatology Unit of North-Western State Medical University named after I.I. Mechnikov. We assessed categories of sex, age, histologic type and location of tumors, pain severity (BAIII), neurologic status (Frankel scale), life span (from operation to death or the latest check-up). Results: The choice of the treatment method depended on the pathology of the spinal tumor. Analysis of the material found: spinal lesion is caused by secondary tumors, mainly; spinal spread results in chest lesions. Positive dynamics of the neurologic status was observed at patients of B,C,D,E groups (Frankel scale) after the surgery. All the patients, having received puncture vertebroplasty, experienced the regression of pain severity. Conclusion: Vertebroplasty is an efficient treatment of pain severity at patients with symptomatic and aggressive haemangeoma and pathologic fractures of vertebral bodies during the neoplastic process. We should apply surgical treatment for patients with spinal cord compression as earlier as possible to prevent from the development of sever neurologic disorders and pain management. The main method of treatment is decompressing and stabilizing interventions from the posterior approach.

Spinal schwannoma is the most common benign intradural spinal tumor. However, studies regarding the neurological outcome of tumor resection in complete paraplegia patients are still lacking. The authors report a case of complete paraplegia due to primary intradural extramedullary low-grade schwannoma of the spinal cord. Surgery was performed 5 weeks after the paraplegia complaint first occurred. The patient did not regain motor nor sensory function in the 1-month follow-up but resolution of pain was achieved. The patient was able to perform daily activity more comfortably. In the event of complete paraplegia, surgery should still be offered promptly as it can still benefit the patient. Possible factors that could have influenced the prognosis in our study are discussed.

Abstract Spinal schwannomas most likely occur at the thoracic level and within the intradural extramedullary compartment. They are benign, typically slow-growing, peripheral nerve sheath tumors that produce symptoms by displacing or compressing the nerve roots and spinal cord. There is an association with patients that have neurofibromatosis type 2. Surgical pearls including the utilization of intraoperative ultrasound for localization, D wave monitoring, and microsurgical dissection are demonstrated. Pertinent high-yield radiographic and histological features of schwannomas are reviewed.1-4  We report the case of a 59-yr-old female who presented with progressively worsening gait instability that was associated with lower extremity numbness progressing to weakness. She had myelopathic findings on examination, which included brisk patellar reflexes and persistent clonus with sensory changes to the umbilicus and mild leg weakness. Full body examination revealed no stigmata of neurofibromatosis. Magnetic resonance imaging of the neuroaxis demonstrated a large, intradural extramedullary mass with peripheral enhancement that spanned the T9 to T11 vertebral levels with severe compression of the spinal cord. There were no intracranial, cervical, or lumbar findings. Surgical intervention was planned with the following objectives: decompression of the neural elements, curative resection, and diagnosis. Patient consent for the procedure was obtained. Institutional Review Board approval for solitary case reports are not needed at our institution.

Neurofibromatosis type 2 (NF2) is an autosomal dominant disorder characterized by multiple tumors including schwannomas, meningiomas and ependymomas of the central nervous system. Although paresthesias, muscle weakness, muscle atrophy, and gait unsteadiness have been reported as clinical symptoms of spinal tumors, there are no reports of patients with NF2 who developed paralysis. A 7-year-old female consulted with our hospital because of sudden bilateral lower limb paralysis. She had not recognized the abnormalities, including paralysis, paraplegia and muscle weakness of bilateral lower limb before administration. Because of the aggravated bilateral patellar tendon reflexes, Achilles tendon reflexes, and the positive bilateral Babinski reflexes, a magnetic resonance imaging (MRI) of the spinal cord was performed. MRI revealed multiple spinal tumors in the cervical, thoracic, lumbar, and sacral regions. In particular, a 12 mm ×  33 mm spinal tumor was present in the thoracic region and was pressing against the spinal cord. Surgery was urgently performed to remove the spinal tumor in the thoracic region. Histopathological examination revealed that the tumor was a schwannoma. Gadolinium-enhanced MRI of the head was performed to explore the intra-cranial lesions: bilateral vestibular schwannomas and tumors in the left oculomotor nerve and right glossopharyngeal nerve were also discovered. Auditory brainstem response was performed to evaluate the bilateral VSs, and the results were normal. Nine months after the surgery, MRI of the head and spinal cord showed that her tumors had not increased in size. This represents the first reported case of NF2 complicated bilateral lower limb paralysis as initial neurological symptom.

Abstract BACKGROUND Radical resection is the first-line option in managing cervical primary chondrosarcoma. Favorable anterior reconstruction is challenging after multilevel total spondylectomy in the cervical spine. OBJECTIVE To illustrate the application of piezoelectric surgery and three-dimensional (3D) printing techniques in spine surgery. METHODS A 27-yr-old patient was referred to our center with complaints of nocturnal neck pain and right upper extremity weakness. A 2-stage radical tumor resection was conducted using piezoelectric surgery with pathologically tumor-free margins. A 3D-printed titanium microporous prosthesis (3D-PTMP) was designed to reconstruct the anterior column of the cervical spine between C1 and T1 for stability. RESULTS The whole intraoperative blood loss was 2300 mL over the 2 procedures. The patient had an uneventful recovery, regaining ambulatory status 3 wk after the 2 operations without ventilator support or other severe complications. By the final 14-mo follow-up, the patient had achieved marked pain relief and favorable neurological improvement; a postoperative computed tomography scan indicated a good position of the 3D-printed construct between the endplates with no sign of tumor recurrence or implant subsidence. CONCLUSION The applications of piezosurgery in total spondylectomy and in 3D-PTMP in reconstruction can be a favorable alternative for managing multilevel cervical spinal tumors. Further studies are warranted to validate this surgical strategy.

OBJECTIVEWith the advent of intraoperative electrophysiological neuromonitoring (IONM), surgical outcomes of various neurosurgical pathologies, such as brain tumors and spinal deformities, have improved. However, its diagnostic and therapeutic value in resecting intradural extramedullary (ID-EM) spinal tumors has not been well documented in the literature. The objective of this study was to summarize the clinical results of IONM in patients with ID-EM spinal tumors.METHODSA retrospective patient database review identified 103 patients with ID-EM spinal tumors who underwent tumor resection with IONM (motor evoked potentials, somatosensory evoked potentials, and free-running electromyography) from January 2010 to December 2015. Patients were classified as those without any new neurological deficits at the 6-month follow-up (group A; n = 86) and those with new deficits (group B; n = 17). Baseline characteristics, clinical outcomes, and IONM findings were collected and statistically analyzed. In addition, a meta-analysis in compliance with the PRISMA guidelines was performed to estimate the overall pooled diagnostic accuracy of IONM in ID-EM spinal tumor resection.RESULTSNo intergroup differences were discovered between the groups regarding baseline characteristics and operative data. In multivariate analysis, significant IONM changes (p < 0.001) and tumor location (thoracic vs others, p = 0.018) were associated with new neurological deficits at the 6-month follow-up. In predicting these changes, IONM yielded a sensitivity of 82.4% (14/17), specificity of 90.7% (78/86), positive predictive value (PPV) of 63.6% (14/22), negative predictive value (NPV) of 96.3% (78/81), and area under the curve (AUC) of 0.893. The diagnostic value slightly decreased in patients with schwannomas (AUC = 0.875) and thoracic tumors (AUC = 0.842). Among 81 patients who did not demonstrate significant IONM changes at the end of surgery, 19 patients (23.5%) exhibited temporary intraoperative exacerbation of IONM signals, which were recovered by interruption of surgical maneuvers; none of these patients developed new neurological deficits postoperatively. Including the present study, 5 articles encompassing 323 patients were eligible for this meta-analysis, and the overall pooled diagnostic value of IONM was a sensitivity of 77.9%, a specificity of 91.1%, PPV of 56.7%, and NPV of 95.7%.CONCLUSIONSIONM for the resection of ID-EM spinal tumors is a reasonable modality to predict new postoperative neurological deficits at the 6-month follow-up. Future prospective studies are warranted to further elucidate its diagnostic and therapeutic utility.
