Transcranial Corticospinal Motor-Evoked Potentials in Cases of Ventral and Ventrolateral Intradural Extramedullary Cervical Spinal Cord Tumors. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:1488. [PMID: 39336529 PMCID: PMC11434370 DOI: 10.3390/medicina60091488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/21/2024] [Revised: 09/08/2024] [Accepted: 09/10/2024] [Indexed: 09/30/2024]
Abstract
Background and Objectives: We studied the clinical significance of an amplitude decrement and disappearance alarm criteria in transcranial motor-evoked potential (MEP) monitoring during surgeries on extramedullary tumors at the cervical spine with reference to postoperative morbidity. Material and Methods: We diagnosed and surgically treated fourteen patients with intradural extramedullary ventral or ventrolateral lesions to the cervical spinal cord in the Clinic of Neurosurgery at the University Hospital St Ivan Rilski from January 2018 to July 2022. Eight cases were diagnosed with schwannoma, and the remaining six had meningiomas. The follow-up period for neurological assessment was six months. Results: A decrease in the intraoperative transcranial MEPs of 50% or more compared to baseline in two cases (14.3%) resulted in an immediate postoperative motor deficit. One patient demonstrated full neurological recovery within six months, while the other exhibited only partial improvement. In six cases (42.9%) with preoperative motor deficits, tumor resection and decompression of the cervical spinal cord led directly to an increment of the transcranial MEPs by more than 20%. Postoperatively and at the 6-month follow-up, these patients showed recovery from the preoperative deficits. In the remaining cases, MEPs were stable during surgery with no clinical deterioration of the motor function. Conclusions: The decremented MEP criteria corresponded to postoperative motor deficit, whereas the improvement of the same parameters after decompression implied future recovery of preoperative motor deficits. The combination of different MEP criteria is likely to be helpful when tailored to a specific case of ventral or ventrolateral extramedullary lesions in the cervical spine.

Characteristics and Outcome of Surgically Treated Patients with Intradural Extra- and Intramedullary Spinal Metastasis-A Single-Center Retrospective Case Series and Review. Curr Oncol 2024; 31:4079-4092. [PMID: 39057176 PMCID: PMC11275473 DOI: 10.3390/curroncol31070304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2024] [Revised: 07/17/2024] [Accepted: 07/18/2024] [Indexed: 07/28/2024] Open
Abstract
OBJECTIVE Intradural spinal metastases are considered rare. At present, limited information is available on incidence, surgical management, and outcomes. METHODS We conducted a retrospective patient chart review from 2002 to 2024, identifying all patients surgically treated for intradural spinal metastases. Clinical, surgical and survival data were collected and compared to literature data for patients surgically treated for extradural spinal metastases. RESULTS A total of 172 patients with spinal metastases were identified with 13 patients meeting inclusion criteria (7.6%). The mean age at diagnosis of intradural spinal metastases was 52 ± 22 years, with diverse primaries including lung (n = 3), breast (n = 2), sarcoma (n = 2), and six unique entities. Intradural spinal metastasis was diagnosed on average of 3.3 years after primary diagnosis. In total, we observed five (38%) intradural-extramedullary and eight (62%) intramedullary metastases, located in the cervical (38.5%), thoracic (46.1%) and lumbar spine (15.4%). The most common preoperative symptoms were pain, sensory changes, and gait ataxia (each 76.9%). Gross total resection was achieved in 54%, and local tumor control in 85%. Postoperatively, 92% exhibited clinical improvement or stability. Most frequent adjuvant treatment was radio- and/or chemotherapy in 85%. The average survival after operation for spinal intradural metastases was 5 months, ranging from 1 month to 120 months. The location of the intradural metastasis in the cervical spine was associated with a significantly more favorable survival outcome (compared to thoracic/lumbar location, p = 0.02). CONCLUSIONS Intradural location of spinal metastases is rare (7.6%). Even so, surgical resection is safe and effective for neurological improvement, and survival appears lower compared to the reported survival of extradural spinal metastases.

Front Neurol 2024; 15:1383980. [PMID: 38863508 PMCID: PMC11165109 DOI: 10.3389/fneur.2024.1383980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Accepted: 04/30/2024] [Indexed: 06/13/2024] Open
Abstract
Objective Spinal schwannomas are the most common intradural extramedullary tumors, and their complete removal is recommended to avoid tumor recurrence. Although laminoplasty provides a sufficient window for tumor resection, this approach may increase tissue trauma and cause postoperative instability compared with unilateral hemilaminectomy. This study aimed to compare the efficacy and clinical outcomes of the two approaches. Materials and methods We included 100 consecutive patients who underwent unilateral hemilaminectomy or laminoplasty for resection of spinal schwannomas between January 2015 and February 2023. The patients' baseline characteristics, including sex, age, tumor location, percentage of tumor occupying the intradural space, operative time, postoperative length of hospital stay, intraoperative bleeding volume, visual analog scale score, and neurologic results, were retrospectively analyzed. Results Hemilaminectomy patients who underwent unilateral hemilaminectomy had smaller intraoperative bleeding (p = 0.020) volume, shorter operative time (p = 0.012), and shorter postoperative length of hospital stay (p = 0.044). The mean VAS scores at the last follow-up were similar between the two groups (p = 0.658). Although the postoperative McCormick and Karnofsky Performance scores were not significantly different between the laminoplasty and unilateral hemilaminectomy groups (p = 0.687 and p = 0.649, respectively), there was a statistically significant improvement based on postoperative neurological results compared to preoperative neurological results for both groups. The incidence of postoperative complications was 5% and 11.7% in the unilateral hemilaminectomy and laminoplasty groups, respectively (p = 0.308). Conclusions For spinal schwannoma resection, unilateral hemilaminectomy has more advantages than laminoplasty, including a shorter postoperative hospital stay, faster procedure, and less intraoperative blood loss while achieving the same desired result.

Long-term postoperative outcomes of spinal cellular schwannoma: study of 93 consecutive cases. Spine J 2024; 24:858-866. [PMID: 38272127 DOI: 10.1016/j.spinee.2024.01.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 01/03/2024] [Accepted: 01/16/2024] [Indexed: 01/27/2024]
Abstract
BACKGROUND CONTEXT Cellular schwannoma (CS) is a rare tumor that accounts for 2.8%-5.2% of all benign schwannomas. There is a dearth of up-to-date information on spinal CS in the literature. PURPOSE The aims of this study were to identify the proportion of CS cases amongst spinal benign schwannoma, describe the clinical features of spinal CS, and identify prognostic factors for local recurrence by analyzing data from 93 consecutive CS cases. STUDY DESIGN Retrospective review. PATIENT SAMPLE We analyzed 93 PSGCT screened from 1,706 patients with spine CS who were treated at our institute between 2008 and 2021. OUTCOME MEASURES Demographic, radiographic, operative and postoperative data were recorded and analyzed. METHODS We compared the clinical features of spinal CS from the cervical, thoracic, lumbar and sacral segments. Prognostic factors for local recurrence-free survival (RFS) were identified by the Kaplan-Meier method. Factors with p≤.05 in univariate analysis were subjected to multivariate analysis by Cox regression analysis. RESULTS The proportion of spinal CS in all benign schwannomas was 6.7%. The mean and median follow-up times for the 93 patients in this study were 92.2 and 91.0 months respectively (range 36-182 months). Local recurrence was detected in 11 cases, giving an overall recurrence rate of 11.7%, with one patient death. Statistical analysis revealed that tumor size ≥5 cm, intralesional resection, and Ki-67 ≥5% were independent negative prognostic factors for RFS in spinal CS. CONCLUSIONS Whenever possible, en bloc resection is recommended for spinal CS. Long-term follow-up should be carried out for patients with tumor size ≥5 cm and postoperative pathological Ki-67 ≥5%.

Abstract
BACKGROUND Primary intradural extramedullary (IDEM) lesions are rare, with an incidence of about 1/100,000 person-years. The aim of this study was to investigate their demographic, clinical, imaging, management, histopathological and outcome parameters. Another objective was to evaluate the various predicting factors leading to long-term favorable outcomes, thereby answering the controversial question: when to operate? METHODS This study observed 212 patients of primary IDEM lesions and followed-up for a mean of 53.80 months. The patient's outcome using McCormick grade at follow-up was correlated with age, sex, duration of symptoms, preoperative McCormick grade, tumor location and extent, extradural spread, extent of excision, vascularity, WHO grade and histopathological tumor type. RESULTS Benign nerve sheath tumors were the commonest lesions (47.17% schwannoma, 4.72% Neurofibroma), followed in incidence by meningioma (19.34%). There was predominance of males (57.08%), except in meningiomas (male: female ratio 1:2.15). Pain was the commonest initial symptom (51.88%). Limb weakness was the most common presenting complaint (88.68%). Gross total excision was achieved in 81.60% of cases and 70.75% of patients improved following surgery. The significant factors predicting favorable outcome included preoperative McCormick grade (P=0.001), the vertical extent of the tumor (P=0.027), histopathological tumor type (P=0.023) and WHO grading (P=0.015); and extent of excision had an odds ratio of 1: 2.5. CONCLUSIONS Significant predictors of functional outcome following surgery in IDEM lesions included preoperative McCormick grade, extent of the tumor, tumor type, WHO grading and extent of resection. The authors recommend surgery with the intent of complete tumor excision, before the onset of substantial symptoms, for better outcome.

Abstract
Intramedullary ependymomas should be treated with surgical resection. Different surgical techniques are described for these tumors, such as skipped and long-segment myelotomies. A 31-year-old male patient with a giant thoracic spinal cord ependymoma extending from the level of T5 to T10 was operated on with a skipped myelotomy technique. Although the patient had urinary incontinence and muscle weakness in both legs, the patient's complaints were nearly completely resolved in the fourth postoperative month. Operating with the smallest possible myelotomy has given us preferable results; however, more studies are needed to hypothesize the superiority of this technique over conventional myelotomy.

Abstract
Spinal intradural extramedullary (ID-EM) tumors are pathologies widely treated through a classical open approach. However, minimally invasive surgery is gaining traction as a comparable treatment option because it carries less morbidity and may reduce healthcare costs.This study aimed to compare the clinical and functional outcomes of open versus minimally invasive approaches for patients with ID-EM tumors. We performed a retrospective analysis on prospectively collected data from patients with ID-EM tumors submitted to surgery. Baseline features and operative variables were compared, including surgery duration and estimated blood loss (EBL). Postoperative data covered tumor histology, length of stay (LOS), complication(s), and neurological status (Medical Research Council (MRC) scale) at the last follow-up.In total, 46 patients were included: 30 (65.2%) operated through an open approach and 16 (34.8%) through a minimally invasive surgical (MIS) approach. The predominant histology type was schwannomas (43.5%). Lesions more frequently affected the lumbar spine (34.8%). The tumor dimensions were similar in both cohorts. The minimally invasive approach was on average 76.7 min faster and correlated positively with less EBL (140 mL less than that of the open approach). Patients in the MIS group had shorter LOSs (5.63 days vs. 17.27 days) and had fewer postoperative complications. No significant difference in functional outcome was found.MIS is as effective as the traditional approach in achieving comparable functional outcomes, with advantages such as shorter surgery durations, less blood loss, and shorter hospital LOSs.

Abstract
(1) Background: With the increasing life expectancy in the Western world, an increasing number of old patients presents with spinal meningioma. Considering the benign nature of these tumors, the functional outcome remains of great importance, since more people reach old age in general conditions of well-being and satisfactory autonomy. (2) Methods: We conducted an international multicenter retrospective study to investigate demographic, clinical and radiological data in a population of elderly patients (≥75 years of age) undergoing surgery for SM from January 2000 to December 2020 in four European referral centers. The aim was to identify prognostic and predictive factors for a good postoperative functional outcome. (3) Results: 72 patients were included in the study. Complete tumor resection (Simpson I or II) was achieved in 67 (95.7%) cases. Intraoperative complications were reported in 7 (9.9%) patients while postoperative complications were found in 12 (16.7%). An excellent general postoperative status (McCormick I and II) was achieved in 65.3%. Overall, surgical resection had a good impact on patients’ functional outcome (86.1% either showing an improvement or maintaining a good preoperative status). Uni- and multivariate analyses found that both age and preoperative modified McCormick independently correlated with relative outcome (coeff = −0.058, p = 0.0251; coeff = 0.597, p < 0.0001) and with postoperative status (coeff = 0.058, p = 0.02507; coeff = 0.402, p = 0.00027), respectively. (4) Conclusions: Age and preoperative modified McCormick were found to be independent prognostic factors. Nevertheless, advanced age (≥75), per se, did not seem to contraindicate surgery, even in those with severe preoperative neurological deficits. The functional results sustain the need for surgical resection of SM in the elderly.

Abstract
PurposeIn the present study, the authors intend to identify the spatial relationship between subdural tumors and spinal nerve fibers of cauda equina prior to operation using the coronal MRI of three-dimensional fast-field echo with water-selective excitation (CMRI).MethodsIn total, 30 case series with surgically and pathologically verified subdural tumors were enrolled in the present study. The spatial relationship between subdural tumors and spinal nerve fibers of the cauda equina was assessed via conventional MRI and CMRI by three experts prior to operation. The spatial relationship between subdural tumors and spinal nerve fibers of the cauda equina was classified using CMRI. The accuracy of imaging observation was determined via intraoperative observation.ResultsThough conventional MRI and gadolinium (Gd)-enhanced MRI (Gd MRI) cannot identify the spatial relationship between subdural tumors and spinal nerve fibers of cauda equina in all cases, CMRI can identify it prior to operation and divide the spatial relationship of spinal nerve fibers of cauda equina with subdural tumors into three types. CMRI shows higher sensitivity (97.44%) and specificity (90.47%) in identifying the spatial relationship of spinal nerve fibers of cauda equina with subdural tumors. Additionally, CMRI also showed a substantial agreement with a kappa value of 0.78.ConclusionHerein, the authors first describe a potential novel application that CMRI can successfully identify the spatial relationship between subdural tumors and spinal nerve fibers of cauda equina prior to operation, which play an essential role in making a prudent surgical plan and preventing postoperative nerve damage.SummaryIntraoperative observation confirms spinal nerve fibers of cauda equina are often wrapped into subdural tumors of the thoracolumbar and lumbar region, which can result in a high rate of sensory and motor dysfunction after the operation due to the unconscious about the wrapping of nerves into subdural tumors prior to operation. To date, there is not an effective strategy to identify the wrapping before operation.

Risk factors for recurrence and regrowth of spinal schwannoma. J Orthop Sci 2022; 28:554-559. [PMID: 35382954 DOI: 10.1016/j.jos.2022.03.003] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Revised: 12/15/2021] [Accepted: 03/03/2022] [Indexed: 12/14/2022]
Abstract
BACKGROUND Spinal schwannoma recurs after initial surgery at a rate of 4%-6%, with known risk factors including subtotal resection, multilevel involvement, large tumor size, and malignant histopathology. This study examined risk factors for schwannoma recurrence and residual tumor regrowth. METHODS Sixty-five patients who underwent resection of spinal schwannoma in our department between July 2010 and December 2018 and were followed up for more than 1 year were retrospectively analyzed for age, sex, follow-up duration, imaging and surgical data, recurrence, reoperation, and Japanese Orthopaedic Association scores before and 1 year after surgery. Patients with postoperative recurrence or residual tumor regrowth of >10% at the final visit (R+ group) were compared with patients without recurrence or regrowth (R- group). Multivariate logistic regression analysis was performed to analyze concurrent effects of risk factors on recurrence and regrowth. RESULTS The 65 patients (mean age 52.4 years at surgery) had schwannomas involving cervical (n = 14), thoracic (n = 25), and lumbar (n = 26) spinal levels. Mean follow-up duration was 58 months. Location was intradural in 65%, extradural in 17%, and both intradural and extradural in 18%. There were 4 recurrences (6.2%), and the mean interval between surgery and recurrence was 18.8 months. Seven patients (10.8%) experienced regrowth. Comparing group R+ (n = 11) and group R- (n = 54), univariate analysis showed significant differences in Sridhar tumor classification, giant tumor (Sridhar classification II, IVb, and V), left-right and cranial-caudal tumor size, largest diameter, operative time, blood loss, subtotal resection, reoperation, fusion surgery, and follow-up duration. Multivariate logistic regression analysis revealed giant tumor (Sridhar classification types II, IVb, and V) as an independent risk factor for recurrence and regrowth. CONCLUSIONS This retrospective review of 65 consecutive patients with spinal schwannoma in a single institution demonstrated that 16.9% had recurrence or regrowth, demonstrating that this potential risk should be kept in mind.

Abstract
Context: Metastatic intradural extramedullary spinal cord tumors are extremely rare.Findings: A 76-year-old woman presented with intractable neck pain. Three years earlier, she had been treated for ovarian cancer with bilateral salpingo-oophorectomy. A year later, she underwent resection of a brain metastasis. Magnetic resonance imaging (MRI) showed an encapsulated intradural extramedullary mass at C4-C5. C4-C5 hemilaminectomy, tumor resection, and biopsy were performed. Histological examination of the resection revealed an adenocarcinoma. After surgery, her intolerable neck-shoulder pain was fully resolved, and she had no difficulties with daily living activities. However, two months later, she underwent gamma knife radiosurgery for the recurrent metastatic brain tumor, and four months later, she died from cachexia.Conclusion: Although cases of metastatic intradural extramedullary spinal tumors from ovarian cancer are extremely rare, their possibility should be considered in the differential diagnosis. A history of brain metastases and enhancement on T1-weighted MRI were helpful for making an accurate diagnosis.

Abstract
BACKGROUND The anatomical features of the atlantoaxial spine increase the difficulty of complete and safe removal of atlantoaxial intradural extramedullary (IDEM) tumors. Studies concerning surgical interventions via a posterior approach are limited.
AIM To investigate the safety and efficacy of atlantoaxial IDEM tumor resection using a one-stage posterior approach.
METHODS We retrospectively analyzed clinical databases for one-stage atlantoaxial IDEM tumor resection via a posterior approach between January 2008 and January 2018. The analyzed data included tumor position, histopathological type, pre- and post-operative Japanese Orthopedic Association (JOA) scores and Nurick grades, postoperative complication and recurrence status.
RESULTS A total of 13 patients who underwent C1-C2 Laminectomy and/or unilateral facetectomy via the posterior approach were enrolled in the study. In all cases reviewed, total tumor resection and concomitant C1-C2 fusion were achieved. The average follow-up was 35.3 ± 6.9 mo (range, 26-49 mo). A statistically significant difference was noted between the preoperative JOA score (11.2 ± 1.1) and the score at the last final follow-up (15.6 ± 1.0) (P < 0.05). A statistically significant difference was noted between the preoperative Nurick grade (2.3 ± 0.9) and that at the last follow-up (1.2 ± 0.4) (P < 0.05). However, no statistically significant difference was noted between the preoperative and last follow-up C1-2 Cobb angle and C2-7 Cobb angle (P > 0.05). No mortalities, severe complications or tumor recurrence were observed during the follow-up period.
CONCLUSION Total resection of atlantoaxial IDEM tumors is feasible and effective via a posterior approach. Surgical reconstruction should be considered to avoid iatrogenic kyphosis and improve spinal stability and overall clinical outcomes.

Abstract
Background
Early diagnosis of spinal cord neoplasia serves patients from developing a number of complications and even death.
Methods
After obtaining ethical approval, retrospectively, a total of 53 tissue blocks of patients attended at the spinal ward were reviewed. Statistical analysis was done using SPSS version 20.0, and p value of less than 0.05 was applied to establish the existence of statistical significance between the compared categorical variables.
Results
The mean age of the patients was 30.7 ± 15.96 years. Most of the patients 32.1% (n = 17) were aged ≤ 19 years, and majority of the neoplasia 77.3% (n = 41) were extramedullary. Also, majority of the neoplasia 60.4% (n = 32) were benign and the malignant ones were 35.8% (n = 19). The mean duration of onset of symptoms for benign and malignant neoplasia in this study was 13.1 ± 16.4 and 3.4 ± 2.8 years, respectively, with statistical difference (95% CI 2.09–17.35, p = 0.014).
Conclusion
The patients with spinal cord neoplasia in the present study were of young age, and majority of them had benign neoplasia that were extramedullary located. The mean duration of onset of symptoms for patients with malignant neoplasia was significantly shorter than that of benign neoplasia.

Abstract
Abstract
Introduction Primary spinal cord tumors are amenable to total surgical excision but the outcomes are still diverse.
Objective The purpose of this study is to identify the significant factors which influence the long-term outcome of spinal cord tumors.
Materials and Methods A total of 84 consecutive spinal cord tumor patients who underwent microsurgical excision during April 2003 to 2014 were retrospectively studied. Patients operated after April 2014 were not considered. Ten factors were taken and correlated with the outcome. Multiple regression analysis was used. Patients were periodically evaluated at 1, 6 months, 1, 2, and 5 years. In 72 cases, postoperative MRI scans were performed. The follow-up period ranged between 5 to 15 years.
Results In our study, we had 64 extramedullary tumors and 21 intramedullary tumors with varied pathology. Axial location of the tumour (20.294/0.000), extent of the resection of the tumour (13.827/0.001), preoperative Nurick grade (11.349/0.023), and location of the tumour in the spine with respect to vertebral segments (8.151/0.017) were significant predictive factors. We had good outcomes in 65 cases and poor outcomes in 19 cases.
Conclusion Our results show location of the tumor with respect to axial plane and vertebral segments were the main contributing factors. They influence the extent of excision of the spinal cord tumor. Preoperative neurological status is the fourth factor which independently determines the long-term outcome. It is one of the few papers where patients have been followed-up for a long period ranging from 5 to 15 years.

Abstract
Background Headache due to raised intracranial pressure is rarely caused by spinal lesions. We describe a patient with primary histiocytic sarcoma who presented with a new onset headache with features of raised intracranial pressure and subtle signs of cauda equina syndrome due to predominant lower spinal cord infiltration and minimal intracranial involvement. Case A previously well 54-year-old man presented with a 2-month history of new onset headache with features of raised intracranial pressure. Progression of lower limb weakness was delayed and mild with diagnostic delay resulting from the primary presentation with headache leading to an initial focus on cerebral pathology. Subsequent investigations revealed a previously unreported presentation of primary histiocytic sarcoma infiltrating the cauda equina causing raised intracranial pressure headache. Conclusion This case highlights the importance of a broad search in the investigation of new onset raised intracranial pressure headache, including imaging of the lower spinal cord. Primary histiocytic sarcoma should be considered in the differential diagnosis of this rare syndrome.

Abstract
Background: The purpose of the current study is to identify the correlations between the most important preoperative clinical factors and the outcome of surgery of spinal meningiomas (SM). Methods: We performed a retrospective analysis of the medical history, clinical, paraclinical, neuroimaging, and surgical protocol data in 31 patients with SM who underwent surgical resection at our institution from January 2011 to July 2020. The degree of resection was assessed on the Simpson scale. The modified McCormick scale was used to monitor the effect and outcome of treatment at admission, discharge, and at further follow-up. Results: The average age of the patients was 65 years (37-78). Vertebral pain and motor deficits were the most common initial symptoms that occurred in 26 (89.6%) and 29 (93.5%) patients, respectively. Sphincter disorders were found in 9 (29%) patients. Total resection (Simpson Grade I – II) was achieved in 29 patients (93.5%). We achieved a favorable outcome (McCormick Gr. I to III) in 93.3% of patients. The degree of the neurological deficit (P = 0.026) and the presence of sphincter disorders (P = 0.009) were the preoperative clinical factors that most significantly correlated with the outcome of treatment. Conclusion: The outcome from the surgical treatment of SM correlated significantly with the degree of the preoperative neurological deficit. Therefore, patients presenting with more severe symptoms are expected to have worse outcomes.

Abstract
Hemangioblastomas are low-grade, highly vascular tumors that are usually associated with von Hippel-Lindau syndrome. Hemangioblastomas most commonly occur in the cerebellum, and intradural extramedullary hemangioblastoma of the cauda equina is very rare, especially in patients without von Hippel-Lindau syndrome. Herein, we report a case of intradural extramedullary hemangioblastoma of the cauda equina that was not associated with von Hippel-Lindau syndrome, with a focus on its imaging characteristics and differential diagnoses. We compared the clinical presentation and imaging features of our case with those of previously reported cases in the review of the literature.

Abstract
OBJECTIVE Ventrally situated thoracic intradural extramedullary tumors are surgically challenging and difficult to access, and they may be complicated by extensive adhesions and calcifications. Selecting an approach for adequate ventral access is key to complete resection and optimization of outcomes. The authors present a case series of patients who underwent resection of ventral thoracic intradural extramedullary tumors and discuss indications and considerations for this technique. Additionally, they describe the use of a posterolateral transpedicular approach for resection of ventral thoracic intradural extramedullary tumors compared with other techniques, and they summarize the literature supporting its application. METHODS From May 2017 to August 2020, 5 patients with ventral thoracic intradural extramedullary tumors underwent resection at one of the two academic institutions. RESULTS Patient ages ranged from 47 to 75 (mean 63.4) years. All tumors were diagnosed as meningiomas or schwannomas by histological examination. Three of the 5 patients had evidence of partial or extensive tumor calcification. Four of the 5 patients underwent an initial posterolateral transpedicular approach for resection, with positive radiographic and clinical outcomes from surgery. One patient initially underwent an unsuccessful traditional direct posterior approach and required additional resection 2 years later after interval disease progression. There were no postoperative wound infections, CSF leaks, or other complications related to the transpedicular approach. CONCLUSIONS Posterolateral transpedicular tumor resection is a safe technique for the treatment of complex ventrally situated thoracic intradural extramedullary tumors compared with the direct posterior approach. Anecdotally, this approach appears to be particularly beneficial in patients with calcified tumors.

Abstract
INTRODUCTION Spinal meningiomas represent 25-45% of intradural spinal tumors and ~2% of meningiomas of the central nervous system (CNS), and their occurrence during pregnancy is unusual. We present an updated literature review. CASE REPORT A 36-year-old woman, at 32.6 weeks of gestation, was hospitalized for urinary tract infection and urinary retention. One month earlier, she had decreased strength in lower limbs, and this weakness rapidly progressed to flaccid paraplegia without sphincters control. Magnetic resonance imaging (MRI) revealed a well-defined intradural extramedullary lesion in T3-T4. Using a posterolateral approach, the tumor was completely removed; however, there was no clinical improvement, and the patient was discharged with an impairment scale (AIS) grade A. Histopathology examination indicated a psammomatous meningioma. DISCUSSION Meningiomas are benign tumors that are slowly progressive; however, the hemodynamic and hormonal changes of pregnancy are related to their accelerated growth. Reports show that the onset of the symptoms during the third trimester of pregnancy, including early neurological symptoms or signs of spinal cord compression, can be easily attributed to those of pregnancy by both the patient and the doctor. The time to diagnosis and medulla compression time are thus prolonged, which can be further compounded in middle-high income countries due to limitations in obtaining images for evaluation. Although rare, spinal meningiomas should be considered in the differential diagnosis of patients with neurological symptoms during pregnancy. Their early recognition is important to avoid irreversible neurological damage.

Complete Excision of Intradural-Extraforaminal Spinal Tumors Using a Minimally Invasive 2-Incision Technique With Fixed Tubular Retractors. Clin Spine Surg 2021; 34:92-102. [PMID: 32694469 DOI: 10.1097/bsd.0000000000001036] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2019] [Accepted: 02/17/2020] [Indexed: 12/12/2022]
Abstract
Spinal tumors are rare, of which intradural-extramedullary lesions form the majority of primary spinal tumors. Occasionally these may even be large, dumbbell shaped, with both intraspinal and extraspinal components. Complete gross total resection is the gold standard in the removal of these tumors since most are benign in nature. Traditionally this has been achieved using large open midline approaches that involve significant muscle dissection, extensive laminectomy, and even facetectomy. This may lead to instability, requiring stabilization to prevent deformity. Minimally invasive surgical approaches using fixed tubular retractors may obviate this need by minimizing the amount of muscle stripping and bony resection required for complete tumor excision. By utilizing facet sparing corridors, the authors describe a novel 2-incision minimally invasive surgical technique that combines a paramedian and a far-lateral approach to access both the intraspinal and extraforaminal, paraspinal portions of the tumor for achieving complete excision. Three illustrative cases are discussed with tumors in 2 different spinal locations that highlights the versatility of this technique-1 in the cervical region and the other 2 in the thoracolumbar region.

Abstract
Objective: Intradural Extramedullary (IDEM) tumors are usually treated with surgical excision. The aim of this study was to investigate the impact on clinical outcomes of pre-surgical clinical conditions, intraoperative neurophysiological monitoring (IONM), surgical access to the spinal canal, histology, degree of resection and intra/postoperative complications. Methods: This is a retrospective observational study analyzing data of patients suffering from IDEM tumors who underwent surgical treatment over a 12 year period in a double-center experience. Data were extracted from a prospectively maintained database and included: sex, age at diagnosis, clinical status according to the modified McCormick Scale (Grades I-V) at admission, discharge, and follow-up, tumor histology, type of surgical access to the spinal canal (bilateral laminectomy vs. monolateral laminectomy vs. laminoplasty), degree of surgical removal, use and type of IONM, occurrence and type of intraoperative complications, use of Ultrasonic Aspirator (CUSA), radiological follow-up. Results: A total number of 249 patients was included with a mean follow-up of 48.3 months. Gross total resection was achieved in 210 patients (84.3%) mostly in Schwannomas (45.2%) and Meningiomas (40.4%). IONM was performed in 162 procedures (65%) and D-wave was recorded in 64.2% of all cervical and thoracic locations (99 patients). The linear regression diagram for McCormick grades before and after surgery (follow-up) showed a correlation between preoperative and postoperative clinical status. A statistically significant correlation was found between absence of worsening of clinical condition at follow-up and use of IONM at follow-up (p = 0.01) but not at discharge. No associations were found between the choice of surgical approach and the extent of resection (p = 0.79), the presence of recurrence or residual tumor (p = 0.14) or CSF leakage (p = 0.25). The extent of resection was not associated with the use of IONM (p = 0.91) or CUSA (p = 0.19). Conclusion: A reliable prediction of clinical improvement could be made based on pre-operative clinical status. The use of IONM resulted in better clinical outcomes at follow-up (not at discharge), but no associations were found with the extent of resection. The use of minimally invasive approaches such as monolateral laminectomy showed to be effective and not associated with worse outcomes or increased complications.

Abstract
Background: Clear cell ependymomas (CCEs) are a rare variant of tumors of the nervous system, the main location is the intracranial compartment. Special differential diagnosis should be done with oligodendrogliomas, neurocytoma, glioneurocytoma, astrocytoma, or metastatic renal cell carcinoma, lesions that somehow share cells with clear cytoplasm. Most of these lesions are benign but differential diagnosis is essential to decide further treatment. Few case reports of intramedullary CCEs have being published and there is no strict consensus on the diagnostic criteria. Case Description: We hereby describe a new case of an intramedullary clear CCE with very few neurological symptoms, surgical treatment is satisfactory, histological and immunohistochemical analysis was confirmatory. After gross total resection and 3-year follow-up no recurrence of the lesion is evident. Conclusion: After this case presentation and review of the limited literature, it is evident that methodical clinical suspicion, radiological imaging combined with histological, and modern immunohistochemical techniques are essential for the diagnosis. Surgical options with gross total resection remain the cornerstone of its treatment. Neurophysiological monitoring is extremely useful to avoid postoperative morbidity.

Abstract
Background: In recent years, improvements in oncological care have led to an increased incidence of intradural extramedullary spinal metastases (IESMs) attributed to uterine carcinosarcoma (UCS). When such lesions occur, they typically carry a poor prognosis. Here, we have evaluated newer treatments, management strategies, and outcomes for IESM due to UCS. Case Description: A 59-year-old female with a history of recurrent UCS presented with the new onset of the left lower extremity pain, numbness, and episodic urinary incontinence. When the MR revealed an enhancing intradural extramedullary mass posterior to the L1 vertebral body, she underwent a focal decompressive laminectomy. Although she improved neurologically postoperatively, she succumbed to the leptomeningeal spread of her disease within 2 postoperative months. Conclusion: Management of IESM due to UCS requires multifaceted, individualized treatment modalities, including neurosurgery, radiation therapy, and medical oncologic management to maximize outcomes.

Abstract
Stereotactic radiation treatment can be used to treat spinal cord neoplasms in patients with either unresectable lesions or residual disease after surgical resection. While treatment guidelines have been suggested for epidural lesions, the utility of stereotactic radiation for intradural and intramedullary malignancies is still debated. Prior reports have suggested that stereotactic radiation approaches can be used for effective tumor control and symptom management. Treatment-related toxicity has been documented in rare subsets of patients, though the incidences of injury are not directly correlated with higher radiation doses. Further studies are needed to assess the factors that influence the risk of radiation-induced myelopathy when treating spinal cord neoplasms with stereotactic radiation, which can include, but may not be limited to, maximum dose, dose-fractionation, irradiated volume, tumor location, histology and treatment history. This review will discuss evidence for current treatment approaches.

Abstract
BACKGROUND Pancreatic neuroendocrine tumors (pNETs) are known to frequently metastasize to the liver and lymphatics; however, metastasis to the spine is exceedingly rare. We report the first case of an intradural, extramedullary pNET metastasis to the upper cervical spine. CASE DESCRIPTION A 75-year-old Hispanic male patient with history of stage IV pNET with metastasis to the liver and lymph nodes and new-onset lymphadenopathy seen on CT of the chest was found on positron emission tomography scan to have a lesion in the cervical spine. The patient was neurologically intact on physical examination, yet given the patient's medical history, magnetic resonance imaging of the cervical spine was performed, revealing a right-sided intradural, extramedullary mass at the C1-C2 level with associated mass effect on the spinal cord, likely representing a schwannoma. Due to the tumor size, mass effect, and the need for definitive tissue diagnosis, a partial C1-C2 laminectomy with intradural resection of the tumor was performed. The histology was consistent with the patient's known pNET. CONCLUSIONS As treatment for pNETs has evolved, there has been a surge in unique presentations of systemic well-differentiated pNETs being reported. It is vital that patients diagnosed with pNET be monitored for metastases, and when discovered, treated promptly.

Abstract
STUDY DESIGN Retrospective analysis. OBJECTIVE The incidence of intradural extramedullary (IDEM) spinal tumors is increasing. Excisional laminectomy for removal and decompression is the standard of care, but complications associated with patient age are unreported in the literature. Our objective is to identify if age is a risk factor for postoperative complications after excisional laminectomy of IDEM spinal tumors. METHODS A retrospective analysis was performed on the 2011 to 2014 ACS-NSQIP (American College of Surgeons National Surgical Quality Improvement Program) database for patients undergoing excisional laminectomy of IDEM spinal tumors. Age groups were determined by interquartile analysis. Chi-squared tests, t tests, and multivariate logistic regression models were employed to identify independent risk factors. Institutional review board approval was not needed. RESULTS A total of 1368 patients met the inclusion criteria for the study. Group 1 (age ≤ 44) contained 372 patients, group 2 (age 45-54) contained 314 patients, group 3 (age 55-66) contained 364 patients, and group 4 (age > 66) contained 318 patients. The univariate analysis showed that mortality and unplanned readmission were highest among patients in group 4 (1.26%, P = .011, and 10.00%, P = .039, respectively). Postoperative wound complications were highest among patients in group 1 (2.15%, P = .009), and postoperative venous thromboembolism and cardiac complications were highest among patients in group 3 (4.4%, P = .007, and 1.10%, P = .032, respectively). Multivariate logistic regression revealed that elderly age was an independent risk factor for postoperative venous thromboembolism (group 3 vs group 1; odds ratio = 6.739, confidence interval = 1.522-29.831, P = .012). CONCLUSIONS This analysis revealed that increased age is an independent risk factor for postoperative venous thromboembolism in patients undergoing excisional laminectomy for IDEM spinal tumors.

Abstract
BACKGROUND With increasing life expectancy and increasing demands on quality of life more spinal meningiomas will limit quality of life in elderly in the coming decades. We investigated whether elderly can improve neurologically and gain self-dependence postoperatively. METHODS Medical records of consecutive spinal meningioma patients from 2004-2015 were retrospectively analyzed. Age, gender, preoperative duration and quality of symptoms, pre- and postoperative McCormick score, Karnofsky Performance Status (KPS), American Society of Anesthesiologists Physical Status (ASA), modified Clinical Scoring System (mCSS) and tumor characteristics were included. Elderly were defined by ≥70 years. RESULTS One hundred and twenty-nine patients were included, of whom 44 were 70 years or older. Younger patients were significantly better preoperatively in McCormick, KPS, ASA and mCSS within the first postoperative year. Both younger and elderly patients improved significantly postoperatively in McCormick, KPS and mCSS. Surgical complication rate was similar for younger and elderly patients (5.9 vs. 6.8%). Systemic complication rate was higher in elderly (0 vs. 6.8%). CONCLUSIONS Surgery for spinal meningioma in elderly (KPS≥40 and ASA≤III) leads to a significant improvement of McCormick, KPS and mCSS postoperatively. This leads to a higher rate of self-dependency and thereby probably to an improvement of quality of life in elderly. However, special attention for systemic complications is necessary.

Abstract
RATIONALE False localizing sign means that the lesion, which is the cause of the symptom, is remote or distant from the anatomical site predicted by neurological examination. This concept contradicts the classical clinicoanatomical correlation paradigm underlying neurological examinations. PATIENT CONCERNS A 54-year-old man consulted for the right sciatica-like leg pain that had aggravated 1 year ago. Radiological examinations revealed degenerative spondylolisthesis with instability and right-sided recess stenosis at the L4-5 level. After initial improvement following 3 transforaminal epidural steroid injections with gabapentin and antidepressant medication, there was a recurrence of the symptoms a year later, along with wasting of the right leg for several months. Physical examination revealed difficulty in heel-walking and a weakness of extension of the right big toe; tendon reflexes were normal. Lumbar spine radiographs revealed no new findings. The initial course of treatment was repeated, but was ineffective. DIAGNOSES Further cervicothoracic spine evaluations revealed a right-sided intradural-extramedullary mass and myelopathy at the C1-2 level. INTERVENTIONS The cervical mass was surgically resected and identified histopathologically as a schwannoma. OUTCOMES Immediately after surgery, sciatica-like pain and weakness of right leg were completely resolved. LESSONS It is difficult to make an accurate diagnosis if there are symptoms caused by false localizing sign. Additionally, it is even more difficult to diagnose false localizing sign accurately when there is a co-existing lumbar lesion that can cause the similar symptoms.

Abstract
Object: The incidence of cerebrospinal fluid (CSF)-related complications after intradural spinal tumor (IST) surgery is high and reported in up to 18% of patients. However, no efficient way to prevent those complications has been reported so far. Treating these complications may require prolonged bed rest, re-exploration, external lumbar drain, use of antibiotics, and possible precipitation of other complications. To alleviate the risk of CSF-related complications, we prospectively adopted the intraoperative use of autologous fat grafting after IST surgery. Methods: This is a perspective analysis of 37 cases (out of 40 cases series) that a prospective use of abdominal fat autograft was applied during dural closure. After the tumor was resected and the dura closed, we used the Valsalva maneuver to ensure watertight closure. CSF leak was prevented with the enforcement of suture with a fat autograft as necessary. In addition a thin layer of fat tissue was then placed over the dura to obliterate any dead space. Fibrin glue was then applied over the graft. Filling the dead space with the fat graft prevented a low-pressure space in which CSF could pool and form a pseudomeningocele. Results: After adopting the fat autograft technique, we did not observe any post-surgery CSF-related complications in any of these patients. Conclusions: The prospective use of autologous fat grafting can ensure watertight dural closure and obliterate the dead space created during surgical exposure and bone removal. This technique significantly reduces, and may completely eliminate, postoperative CSF-related complications in patients with ISTs.

Abstract
PURPOSE Primary spinal cord glioma is a rare entity especially in children; accounting for less than 10% of all central nervous system tumors. Low grade is the most reported subtype. Treatment modalities have largely evolved; large improvements have been made in the surgical field but also in both of radiotherapy and chemotherapy. Nevertheless, the optimal treatment is yet to be defined. MATERIAL AND METHODS A chart review of 11 pediatric patients with a diagnosis of low grade spinal cord glioma at Xhinhua hospital in Shanghai was conducted. A statistical package for Social Sciences Package (SPSS) was used for analysis. Means and standard deviations were calculated. The Kaplan-Meier method was used to analyze overall survival and progression-free survival. RESULTS The mean age was 6.7 years (range: 6 months-14.3 years). Revealing symptoms were variable and slowly progressive. The mean duration of symptoms prior to diagnosis was of 7±3.2 months. Astrocytoma was the most commonly reported histological type (seven cases, 63.6%), ependymomas were reported in three cases (27.3%). Surgery was performed in all patients. Subtotal resection concerned the majority of patients (nine patients, 81.8%). Adjuvant radiotherapy was indicated in all cases. A total dose of 39.6Gy was delivered to the whole group. Three patients received adjuvant chemotherapy, of whom two patients had grade III glioma and one patient had a tumor recurrence. Temozolomide-based regimen was the main protocol used for all our patients. The 3 years overall survival rate was 100%, whereas the progression free survival rate was 87.5%. One case relapsed during the next year following completion of treatment. CONCLUSION Our preliminary results are consistent with that of other similar published reports, however longer follow up is needed. So are specific recommendations that are still lacking in this setting.

Abstract
Stereotactic radiosurgery (SRS) has become an increasingly popular treatment modality for spinal tumors due to its noninvasive and targeted approach. Whether SRS has the promise of relieving pretreatment symptoms and providing local tumor control for patients with intradural spine tumors is still debated. This review explores the current literature on SRS treatment for both metastatic and benign intradural tumors, with a focus on differential use for intramedullary and intradural extramedullary neoplasms. Although mortality rates from underlying malignant disease remain high, SRS may benefit patients with spinal metastatic lesions. Benign tumors have shown a promising response to SRS therapy with low rates of complications. Larger studies are necessary to determine the indications and outcome profile of SRS for intradural spinal neoplasms.

Abstract
Context: In the absence of a community-based study on the spinal tumors in the Valley, medical records of the only Regional Neurosurgical Center are available. Aim: The aim of this study is to establish a hospital-based regional epidemiology of spinal tumors in the Valley since the data are derived from a single institution. Materials and Methods: A retrospective analysis of 531 malignant and nonmalignant tumors of spinal cord, its coverings and vertebrae, which were managed in a Regional Neurosurgical Center under a standard and uniform medical-protocol over 30-year period from 1983 to 2014. Results: The hospital-based incidence for all spinal tumors was 0.24/100,000 persons per year. The malignant spinal cord and vertebral tumors comprised 32.58% (173/531) of all tumors, and benign spinal cord and vertebral tumors comprised 67.42% (358/531). The extradural–intradural tumors such as metastatic lesions and primary malignant vertebral tumors were on rise with 16.38% (87/531) cases. The children below 18 years were 5.46% (29/531), of which 55.17% (16/29) were below 9 years. The most common primary bone malignancy was multiple myeloma (54.54% =12/22). Histopathologically, the most common metastatic deposit in the spinal canal was non-Hodgkin's lymphoma (24.61% =16/65). A mortality of 3.20% (17/531) was noted. Recurrences were noted in 4.90% (26/531), and adjuvant therapies were given to 16.38% (87/531) patients. Conclusion: The malignant spinal cord and vertebral tumors, especially metastatic deposits, are on rise in elderly population. The surgical outcome, in terms of recovery and spinal stability, of benign tumors, is comparatively better than malignant ones. The study reveals a low regional incidence (hospital-based) of spinal tumors.

Abstract
STUDY DESIGN A retrospective analysis of 169 adult patients operated for a conventional spinal schwannoma from the AOSpine Multicenter Primary Spinal Tumors Database. OBJECTIVE The aim of this study is to identify risk factors for local recurrence of conventional spinal schwannoma in patients who had surgery. SUMMARY OF BACKGROUND DATA Schwannomas account for up to 30% of all adult spinal tumors. Total resection is the gold standard for patients with sensory or motor deficits. Local recurrence is reported to be approximately 5% and usually occurs several years after surgery. METHODS Rates and time of local recurrence of spinal schwannoma were quantified. Predictive value of various clinical factors was assessed, including age, gender, tumor size, affected spinal segment, and type of surgery. Descriptive statistics and univariate regression analyses were performed. RESULTS Nine (5.32%) out the 169 patients in this study experienced local recurrence approximately 1.7 years postoperatively. Univariate analyses revealed that recurrence tended to occur more often in younger patients (39.33 ± 14.58 versus 47.01 ± 15.29 years) and in the lumbar segment (55.56%), although this did not reach significance [hazard ratio (HR) 0.96, P = 0.127; and P = 0.195, respectively]. Recurrence also arose in the cervical and sacral spine (22.22%, respectively) but not in the thoracic area. Tumors were significantly larger in patients with recurrence (6.97 ± 4.66 cm versus 3.81 ± 3.34 cm), with extent in the cranial caudal direction posing the greatest hazard (HR = 1.321, P = 0.002). The location of the tumor, whether epidural, intradural, or both (P = 0.246), was not significantly related to recurrence. Regarding surgical technique, over 4 times as many patients who underwent intralesional resection experienced a recurrence proportionally to patients who underwent en bloc resection (HR = 4.178, P = 0.033). CONCLUSION The pre-operative size of the conventional spinal schwannoma and intralesional resection are the main risk factors for local postoperative recurrence. LEVEL OF EVIDENCE 3.

Abstract
Longitudinally extensive transverse myelitis (LETM) is most commonly associated with neuromyelitis optica spectrum disorders (NMOSD). However, a wide range of etiologies may produce longitudinally extensive spinal cord lesions (LESCLs) on imaging. We highlight the case of a patient with a spinal cord tumor whose imaging showed LESCL and was diagnosed with LETM. He did not respond to immunosuppression and subsequently developed a progressive and protracted clinical course. Thoracic cord biopsy performed 6 years after symptom onset showed primary spinal oligoastrocytoma. We discuss the features that should raise suspicion of a neoplasm in the context of LESCL and serve a reminder that not all LESCLs are inflammatory.

Abstract
Background: Spinal intradural extramedullary teratoma is a rare condition, more common in children than in adults often with a history of spinal dysraphism. Method: We reviewed the literature and Pubmed advanced search showed nine results of intradural extramedullary teratoma in adults which included five independent case reports and three cases in a case series. We reported a rare case of intradural extramedullary teratoma in an adult located opposite L4 vertebra with neither spinal dysraphism nor any history of the prior spinal procedure. Results: The occurrence of teratomas in the spine is extremely rare. Further, spinal intradural extramedullary teratoma is more common in children but a rare entity in adults. Conclusion: Although uncommon, spinal cord neoplasm should be considered in the differential diagnosis of backache or radicular pain associated with neurological deficits even in absence of spinal dysraphism or any spinal procedure.

Abstract
OBJECT
Patients with symptomatic intradural-extramedullary (ID-EM) tumors may be successfully treated with resection of the lesion and decompression of associated neural structures. Studies of patients undergoing open resection of these tumors have reported high rates of gross-total resection (GTR) with minimal long-term neurological deficit. Case reports and small case series have suggested that these patients may be successfully treated with minimally invasive surgery (MIS). These studies have been limited by small patient populations. Moreover, there are no studies directly comparing perioperative outcomes between patients treated with open resection and MIS. The objective of this study was to compare perioperative outcomes in patients with ID-EM tumors treated using open resection or MIS.
METHODS
A retrospective review was performed using data collected from 45 consecutive patients treated by open resection or MIS for ID-EM spine tumors. These patients were treated over a 9-year period between April 2003 and October 2012 at Northwestern University and the University of Chicago. Statistical analysis was performed to compare perioperative outcomes between the two groups.
RESULTS
Of the 45 patients in the study, 27 were treated with the MIS approach and 18 were treated with the open approach. Operative time was similar between the two groups: 256.3 minutes in the MIS group versus 241.1 minutes in the open group (p = 0.55). Estimated blood loss was significantly lower in the MIS group (133.7 ml) compared with the open group (558.8 ml) (p < 0.01). A GTR was achieved in 94.4% of the open cases and 92.6% of the MIS cases (p = 0.81).
The mean hospital stay was significantly shorter in the MIS group (3.9 days) compared with the open group (6.1 days) (p < 0.01). There was no significant difference between the complication rates (p = 0.32) and reoperation rates (p = 0.33) between the two groups. Multivariate analysis demonstrated an increased rate of complications in cervical spine tumors (OR 15, p = 0.05).
CONCLUSIONS
Thoracolumbar ID-EM tumors may be safely and effectively treated with either the open approach or an MIS approach, with an equivalent rate of GTR, perioperative complication rate, and operative time. Patients treated with an MIS approach may benefit from a decrease in operative blood loss and shorter hospital stays.

Abstract
Genetic alterations in the cells of intradural spinal tumors can have a significant impact on the treatment options, counseling, and prognosis for patients. Although surgery is the primary therapy for most intradural tumors, radiochemothera-peutic modalities and targeted interventions play an ever-evolving role in treating aggressive cancers and in addressing cancer recurrence in long-term survivors. Recent studies have helped delineate specific genetic and molecular differences between intradural spinal tumors and their intracranial counterparts and have also identified significant variation in therapeutic effects on these tumors. This review discusses the genetic and molecular alterations in the most common intradural spinal tumors in both adult and pediatrie patients, including nerve sheath tumors (that is, neurofibroma and schwannoma), meningioma, ependymoma, astrocytoma (that is, low-grade glioma, anaplastic astrocytoma, and glioblastoma), hemangioblastoma, and medulloblastoma. It also examines the genetics of metastatic tumors to the spinal cord, arising either from the CNS or from systemic sources. Importantly, the impact of this knowledge on therapeutic options and its application to clinical practice are discussed.

Abstract
Intraspinal tumors comprise a large spectrum of neoplasms, including hemangioblastomas, paragangliomas, and meningiomas. These tumors have several common characteristic imaging features, such as highly vascular mass appearance in angiography, hypointense rim and serpentine flow voids in MRI, and intense enhancement after intravenous contrast administration. Due to their rich vascularity, these tumors represent a special challenge for surgical treatment. More recently, the surgical treatment of intraspinal vascular tumors has benefited from the combination of endovascular techniques used to better delineate these lesions and to promote preoperative reduction of volume and tissue blood flow. Endovascular embolization has been proven to be a safe procedure that facilitates the resection of these tumors; hence, it has been proposed as part of the standard of care in their management.

Abstract
PURPOSE This study evaluated the response of spinal meningiomas to treatment, by monitoring changes in magnetic resonance imaging (MRI) findings after stereotactic radiosurgery (SRS). MATERIALS AND METHODS Serial follow-up MRIs of 11 patients with spinal meningiomas who underwent SRS were retrospectively reviewed. Changes in tumor volume, T2 signal intensity (T2SI), and contrast enhancement were evaluated. RESULTS The mean MRI follow-up period was 46.9 months (range 13-108 months). The local tumor control rate was 100 % in overall tumor volume, although boost SRS was performed for marginal recurrence in case 8 and rapid decompression in case 5. Seven tumors showed decreased T2SI. Each of the remaining four tumors showed variable T2SIs. In most tumors, the enhancement patterns did not change. Two of three patients with en plaque type meningiomas showed increased intramedullary T2SI, thought to be due to compressive myelopathy and peritumoral edema. CONCLUSIONS SRS resulted in successful local tumor control in all patients, although the follow-up period was not long. Changes in T2SI and contrast enhancement patterns of the tumors were evaluated on serial MRI. In addition, close follow-up with MRI is desirable to monitor intramedullary signal changes in cases of spinal meningiomas with a wider contact area with the spinal cord.
