Abstract
Background Intradural extramedullary (IDEM) spinal cord tumors account for approximately two-thirds of benign intraspinal neoplasms. These are amenable to gross total excision but can have variable functional outcomes, which plays a key role in assessing their impact on a patient's quality of life. Understanding the functional outcomes associated with these tumors is crucial for healthcare professionals to devise appropriate treatment plans and provide comprehensive care. Methods In this study, we retrospectively reviewed the outcomes of 130 patients with IDEM tumors who underwent surgery in the past six years between January 2017 and December 2022 at a single institution. Patient demographics, symptoms, and tumor characteristics (anatomical and pathological) in all operated spinal IDEM tumors were analyzed. The neurological findings obtained during the preoperative stage and the postoperative follow-up were evaluated according to the Frankel grading. The back pain was assessed using the Denis pain scale (DPS). Results The age range, gender distribution, presentation, histopathology, and tumor characteristics were analyzed. The histopathological outcomes of the study were as follows: 56 cases of schwannoma, 37 cases of meningiomas, 16 patients of neurofibroma, six cases of epidermoid cyst, five cases each of ependymoma and dermoid cyst, three cases of arachnoid cyst, two cases of metastasis, and one case of paraganglioma. Pain was the most common symptom (38.5%), followed by weakness in limbs (31.5%), paresthesia/numbness (22.3%), and sphincter disturbance (7.7%). Complete total resection was seen in 93% of cases, with 7% undergoing subtotal excision. The complications encountered were - four cases of surgical site infection and one case each of cerebrospinal fluid leak, pseudomeningocele, and epidural hematoma. In our series, 49.3% of patients had significantly good improvement in functional outcomes as per improvement in Frankel score, and 43% of patients had good functional improvement. Significant functional improvement was noted at immediate postoperative follow-up, 2-week follow-up, and six-month follow-up periods. Reoccurrence was seen in 7 cases (5.4%). The DPS score mean values showed a significant decrease over the follow-up duration as compared to preoperative mean values. Significantly poor outcome was seen in IDEM tumours present anteriorly. Conclusion The IDEM tumors are usually benign and are readily detected by contrast-enhanced magnetic resonance imaging scans. These have variable functional outcomes in different centers. Assessing this functional outcome is an essential aspect of managing IDEM spinal tumors. It was observed through our study that the ventral location of the tumor, thoracic tumors, and poor preoperative neurological status of the patient correspond with poorer postoperative functional outcomes. Furthermore, a significant decrease in the pain symptoms with improvement of Frankel score was seen postoperatively, thus this being suggestive of a significant improvement of functional outcome after surgery. This study helps to conclude that the morbidity associated with the resection of IDEM tumors is not as significant as originally thought to be.

Spinal Meningioma Surgery through the Ages-Single-Center Experience over Three Decades. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58111549. [PMID: 36363510 PMCID: PMC9698896 DOI: 10.3390/medicina58111549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 10/07/2022] [Accepted: 10/25/2022] [Indexed: 11/07/2022]
Abstract
Background and Objectives: Spinal meningiomas, which are well characterized and are most frequently intradural extramedullary tumors, represent 25% of all intradural spinal tumors. The goal of this study was to compare the outcomes of surgically treated patients with spinal meningiomas in two time intervals with special emphasis on postoperative functional outcomes. Methods: Patients with spinal meningiomas admitted to our department between 1990 and 2020 were enrolled and divided into a historic cohort (HC; treated 1990−2007) and a current cohort (CC; treated 2008−2020). Patients’ clinical data and surgical and radiological reports were retrospectively analyzed up to 5 years. Preoperative and postoperative neurological function were assessed using the modified McCormick Scale (mMCS). The Charlson Comorbidity Index (CCI) was used to evaluate the effect of comorbidities on the preoperative status and postoperative outcome. Results: We included 300 patients. Participants in the CC (n = 144) were significantly younger compared to those in the HC (n = 156), with twice as many patients <50 years of age (p < 0.001). The most common tumor location was the thoracic spine (n = 204). The median follow-up was 38.1 months (±30.3 standard deviation). A symptom duration until surgery <12 months was significantly associated with an earlier improvement in the mMCS (p = 0.045). In the CC, this duration was shorter and patients’ neurological function at the first and last follow-ups was significantly better than for those in the HC (p < 0.001 for both). Conclusions: Our study results suggested that the impact of surgical management and postoperative rehabilitation on spinal meningioma patients’ long-term neurological outcome has reached important milestones over the last decades. An earlier diagnosis led to earlier surgical treatment and improved patients’ postoperative neurological recovery. Our results exposed that surgical therapy for spinal meningioma should be performed within 12 months after appearance of symptoms to achieve a better recovery.

Abstract
Background: Primary spinal cord tumors are rare and heterogeneous, and their prevalence varies among the studies. Few articles have evaluated the prevalence, characteristics, and histological types of spinal cord tumors in Latin American populations. This study aimed to analyze the histological types and clinical aspects of a series of consecutive patients diagnosed with primary spinal cord tumors who underwent surgical treatment in a single Brazilian institution and to compare them with the literature. Methods: This is a case series study, with retrospective analysis of all consecutive adult patients who underwent surgical treatment for primary spinal cord tumors in a single center between January 1997 and April 2021. Data analyzed included age at surgery, sex, anatomical location, histopathological diagnosis, clinical presentation, and neurological status at discharge. Results: A total of 104 patients (53 women [51.0%]; mean age, 49.0 ± 16.7 years [range, 19-87 years]) were included in the analysis. Among the tumors, 83.7% were benign, and 36.5% involved the thoracic spine; intradural extramedullary lesions comprised 52.9% of the tumors, and the most prevalent were schwannomas (26.9%) and meningiomas (18.3%). Among the patients, 55% and 50% presented with pain and motor deficit, respectively, and the deficit improvement rate was greater than the worsening rate at the immediate postoperative period and discharge. Conclusions: Our series highlights the heterogeneity of primary spinal cord tumors compared to other studies. Further large population studies are necessary to elucidate the epidemiology of this disease.

Abstract
Introduction Intradural extramedullary (IDEM) spinal cord tumors account for approximately two-thirds of largely benign intraspinal neoplasms. These are amenable to gross total excision and usually carry a good functional outcome. Methods In this study, we reviewed the surgical outcomes of 35 patients who underwent excision of intradural extramedullary tumors. Patient demographics, severity and duration of symptoms, and tumor characteristics (anatomical and pathological) in all operated spinal IDEM tumors were collected. The neurological findings obtained during the preoperative stage and the postoperative follow-up were evaluated according to the Frankel and Nurick grading. The back pain was assessed with help of the Denis pain scale (DPS). Results The histopathological outcomes of the study were as follows: six patients of neurofibroma, 12 cases of schwannoma, nine cases of meningiomas, three cases of ependymoma, one case of dorsal neurenteric cyst, two cases of epidermoid cyst, one case of cauda equina paraganglioma, and one case of filum terminale dermoid cyst. Paresthesia/numbness were the commonest symptoms (88.6%), weakness of limbs in (80%), sphincter dysfunction in 15 patients (42.9%), and paraplegia was seen in three patients (8.57%). The complications encountered were - one case each of cerebrospinal fluid (CSF) leak, surgical site infection, and pseudomeningocele. The percentage of spinal canal occupied ranged from 71-94%. The mean percentage of the spinal canal occupied by the tumor was 81.8%. In our series, 77.14% of patients (p<0.0001) had good functional outcomes as per improvement in Frankel score. The DPS and Nurick score mean values showed a significant decrease over the follow-up duration as compared to preoperative mean values. Significant functional improvement was noted at the one-week, one-month, and one-year follow-up, with a p-value of <0.0001. Conclusions The IDEM tumors are usually benign and are readily detected by contrast-enhanced MRI scans. These have excellent surgical outcomes with some exceptions. Greater canal occupancy and a longer duration of symptoms are usually seen to correspond with suboptimal functional outcomes.

Abstract
Seventy-three patients with spinal nerve sheath tumor who were surgically treated in our hospital during the years 2004-2010 were retrospectively reviewed with respect to recovery of neurological function, recurrence of the tumor and occurrence of kyphotic deformities. Preoperative clinical manifestations, imaging data, surgical records and follow-up results were comprehensively analyzed. The follow-up duration was 12-60 months with an average of 32.0 months. Out of the 73 cases enrolled, 69 had gradual recovery of sensation, motor and sphincter functions 1 week to 3 months after operation. Forty-six cases had incomplete paralysis, whose American Spinal Injury Association (ASIA) grades, however, were gradually increased during the follow-up period, 4 cases had no significant improvement of the clinical symptoms and no change in ASIA grades during the follow-up period. Two cases had postoperative recurrence of the tumor. There were no deaths, no spinal instability, and no kyphotic malformations found in any cases. Our study indicated that complete removal of the tumor is important for good recovery, and an ideal surgical method may reduce the recurrence of the tumor or the occurrence of complications.

Abstract
Tumors of the central nervous system are common in the pediatric population and constitute the second most prevalent tumor type in children. Within this group, spinal cord tumors are relatively rare and account for 1 to 10% of all pediatric central nervous system tumors. We describe a very rare case of an intradural extramedullary spinal cord tumor with a subcutaneous mass and discuss its clinical presentation, pathogenesis, and treatment. A male infant was delivered normally, with uneventful development. At 16 days post-delivery, his family took him to a pediatrician because of a mass on his upper back. Magnetic resonance imaging of the thoracic spine revealed a well-demarcated soft-tissue mass with central cystic change or necrosis at the subcutaneous layer of the posterior back (T2-7 level). Another mass was found with a fat component at the spinal canal of the T1-3 level, which was intradural extramedullary space. After six weeks, the spinal cord tumor and subcutaneous mass were grossly total resected; pathologic findings indicated an atypical myxoid spindle cell neoplasm, possibly nerve sheath in type. The final diagnosis of the mass was an atypical myxoid spindle cell neoplasm. The postoperative course was uneventful, and the patient was discharged after nine days without any neurological deficit. We report a rare case of an intradural extramedullary spinal tumor with subcutaneous mass in a neonate. It is necessary to monitor the patient's status by examining consecutive radiologic images, and the symptoms and neurological changes should be observed strictly during long-term follow-up.

Abstract
Intradural schwannoma of the conus medullaris is a rare form of spinal neoplasm, which commonly occurs in the lumbar region. Conus medullaris level is unusual for schwannomas. A 49-year-old woman presented with chronic sciatica, mild bladder dysfunction, and paresthesia in the buttocks. Magnetic resonance imaging of the spine showed a mass lesion in the conus medullaris region with nerve compression. The tumor was completely resected and diagnosed histologically as schwannoma. The patient recovered after surgery. Clinical and radiologic features of this rare tumor are reviewed and are accompanied by literature findings.

Abstract
Background We wanted to investigate the results of surgical treatment and analyze the factors that have an influence on the neurologic symptoms and prognosis of spinal intradural extramedullary (IDEM) tumors. Methods The spinal IDEM tumor patients (11 cases) who had been treated by surgical excision and who were followed up more than 1 year were retrospectively analyzed. Pain was evaluated by the visual analogue scale (VAS) and the neurologic function was assessed by Nurick's grade. The pathological diagnosis, the preoperative symptom duration, the tumor location on the sagittal and axial planes and the percentage of tumor occupying the intradural space were investigated. In addition, all these factors were analyzed in relation to the degree of the preoperative symptoms and the prognosis. On the last follow-up, the MRI was checked to evaluate whether or not the tumor had recurred. Results The most common diagnosis was schwannomas (73%), followed by meningiomas (18%). The percentage of tumor occupying the intradural space was 82.9 ± 9.4%. The VAS score was reduced in all cases from 8.0 ± 1.2 to 1.2 ± 0.8 (p = 0.003) and the Nurick's grade was improved in all cases from 3.0 ± 1.3 to 1.0 ± 0.0 (p = 0.005). The preoperative symptoms were correlated with only the percentage of tumor occupying the intradural space (VAS; r2 = 0.75, p = 0.010, Nurick's grade; r2 = 0.69, p = 0.019). One case of schwannoma recurred. Conclusions The degree of neurologic symptoms was correlated with the percentage of tumor occupying the intradural space. All the tumors were able to be excised through the posterior approach. The postoperative neurologic recovery was excellent in all the cases regardless of any condition. Therefore, aggressive surgical excision is recommended even for cases with a long duration of symptoms or a severe neurologic deficit.

Abstract
Spinal schwannomas are frequently observed among patients treated in a reference neurosurgery center. Cystic spinal schwannomas, however, are very scantly found. Due to its indolent behavior and benign course, the diagnosis of schwannomas may pose a challenge to the care giver, and the imaging findings can be misleading. In this article, we illustrate an example of a pauci-symptomatic 55 year-old male patient whose complaint was solely a non specific lumbar pain. Investigation revealed a large cystic lesion comprising the lower lumbar intradural space. He was then treated with microneurosurgical technique involving complete removal of the tumor and reconstruction of the duramater. Histological and immunohystochemical diagnosis were consistent with cystic schwannoma. The patient presented with complete recovery of his symptom. In this article we aim to emphasize the clinical presentation and treatment of lumbar spine schwannomas, and to illustrate the imaging findings within this uncommon case.

Abstract
Twenty-five children with benign intradural extramedullary tumors/lesions were retrospectively analyzed to see the frequency of different histotypes in this location and their variation from the Western world. The duration of symptoms, clinical profile and surgical outcome of these cases were evaluated. The age of children ranged from 1.5 to 18 years, with a mean age of 7.5 years. Thirteen amongst them were male. Follow-up ranged from 3 months to 5 years with a mean of 19 months. McCormick functional grading was used retrospectively to find out the functional outcome in these children. Sixty-eight percent of these cases presented with functional grade IV or V. The mean duration from the appearance of the first symptoms to admission to our hospital in these children was 13 months. Improvement in the functional grade following surgical excision was noted amongst all, except one, who presented with schwannoma, and did not improve from grade III even after a 14-month follow-up. Reoperation/two-staged operation was required in 3 children. The following conclusions were drawn from this study: (1) approximately half (48%) of intradural extramedullary benign tumors are nerve sheath tumors, i.e. neurofibromas, neurilemomas and schwannomas. Giant neurofibromas with giant extraforaminal extension may rarely manifest with a large extraspinal mass; (2) meningioma is an infrequent tumor in this location; (3) developmental cystic dysraphic lesions (neurenteric cyst, arachnoid cysts), unassociated with the stigmata of spinal dysraphism, are significantly more frequent (28%) than reported in the literature; (4) the possibility of infective lesions (granuloma, abscess) causing compressive features cannot be denied even in intradural extramedullary tumors; (5) long-standing lesions, with a long segment involvement, also have a good outcome following a good microsurgical excision, and (6) more than half of the children (68%) present with a severe neurological compromise, either because of ignorance and poor education or due to the scanty diagnostic facilities available at the peripheral hospitals of the developing milieu.

Abstract
Chondrosarcomas are malignant tumors that rarely grow inside the spinal canal. Prognosis depends on histological features, patient's age and surgical margins free from tumor. Response to radio and chemotherapy is poor. Ideal treatment consists of total " en-block" resection, not always achievable due to limitation of location, compromise of stability and risk of inducing neurological deficits. Two cases of spinal chondrosarcoma causing cord compression are reported, located in the cervical and thoracic spine. Microsurgical technique consisted of initial debulking followed by removal of margins until limits free from tumor were obtained. Total resection was accomplished and neurological function improved in both cases. Follow-up has been seven and one year respectively, with no evidence of recurrence and preserved neurological functions. Association between chondrosarcoma and estrogen-dependent tumor has been confirmed in this report. Although " en-block" resection of a chondrosarcoma should be tried whenever possible, tumor fragmentation should be considered in difficult cases, as in the present report, in which a long period free from recurrence with good quality of life can be obtained.
