H3K27M-mutant glioma in thoracic spinal cord and conus medullaris with pilocytic astrocytoma morphology: case report and review of the literature. Br J Neurosurg 2024; 38:1020-1026. [PMID: 34615413 DOI: 10.1080/02688697.2021.1988054] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2021] [Revised: 08/26/2021] [Accepted: 09/28/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND The H3K27M-mutant spinal cord gliomas are very aggressive with a dismal prognosis, very few cases have been reported in the thoracic spinal cord and conus medullaris, and it is extremely rare with morphological features of pilocytic astrocytoma. CASE PRESENTATION A 20-year-old man presented with thoracolumbar pain, progressive paraparesis, and urinary incontinence. Magnetic resonance imaging revealed an intramedullary solid-cystic lesion from D9 to conus medullaris. Subtotal resection was performed, restricted by the indistinct margins and the decline of the motor evoked potential during the surgery. Pathologic findings revealed a pilocytic astrocytoma with anaplastic features. However, a further assessment determined a diffuse midline glioma H3K27M-mutant, and adjuvant chemoradiotherapy was administered. After seven months of progression-free survival, the paraparesis worsened; at twelve months of follow-up, the patient developed paraplegia, and at 24 months the patient remains alive without any neurologic functions distal to the tumor and he is still under adjuvant treatment. CONCLUSIONS The H3K27M-mutant spinal cord glioma is a very infrequent tumor with a wide variety of histological presentations even as indolent as pilocytic astrocytoma, which should be considered in spinal cord tumors, especially if there are clinical, histological, or radiological data that suggest aggressiveness. On the other hand, the fast progression led to the loss of complete neurological function distal to the tumor, in spinal tumors could explain a not so poor prognosis as it is in functionally and vital structures.

Abstract
PURPOSE Intramedullary spinal cord tumors are an uncommon pathology in adults and children. Most descriptive studies of intramedullary spinal cord tumors have not focused on a possible association with future brain lesions. To the best of our knowledge, few reports describe this potential relationship. This is one of the most extensive case series of secondary brain lesions of intramedullary spinal cord tumors in the pediatric population. METHODS Retrospective chart review was performed on pediatric patients (21 years old and younger) who underwent resection of an intramedullary spinal cord tumor at two tertiary care hospitals from 2001 to 2020. Patients previously treated or diagnosed with spinal cord tumor, and subsequent development of intracranial manifestation of the same or different tumor, were included. Data regarding epidemiology, surgical intervention, and clinical and follow-up course were gathered. Data analysis was performed according to a standardized clinical protocol with a literature review. RESULT More than 500 patients underwent intradural spinal tumor resection surgeries at participating hospitals from 2001 to 2020. After excluding adult patients (older than 21 years old) and those with extramedullary lesions, 103 pediatric patients were identified who underwent resection of an intramedullary spinal cord tumor. Four underwent resection of an intermedullary tumor and later in their follow-up course developed a secondary intracranial neoplasm. In every case, the secondary neoplasm had the same pathology as the intramedullary tumor. Three of the patients had tumors at the cervico-thoracic junction, and one patient had a high cervical tumor. These patients had a negative primary workup for any metastatic disease at the time of the presentation or diagnosis. Complete and near complete resection was performed in three patients and subtotal in one patient. CONCLUSION Secondary brain tumors disseminated after initial spinal cord tumor are extremely rare. This study aims to allow specialists to better understand these pathologies and treat these rare tumors with more certainty and better expectations of unusual associated lesions and conditions.

Abstract
ABSTRACT Primary and metastatic spine tumors can lead to devastating complications, but timely and careful management of these patients can improve outcomes. A multidisciplinary and structured approach is the most effective way to evaluate patients with spine disease and mitigate the risk of complications. The neurologic, oncologic, mechanical and systemic disease framework gives comprehensive guidance to providers regarding appropriate management. Physiatrists play a critical role in these patients' initial evaluation and continued management throughout cancer treatment. Patients with spinal cord involvement have extensive needs, requiring an individualized management approach. Even though patients with nontraumatic spinal cord injury benefit from rehabilitation efforts and have improved outcomes, they are not routinely admitted to inpatient rehabilitation units or referred to outpatient cancer rehabilitation. Ongoing efforts are needed to promote rehabilitation medicine involvement in improving functional outcomes and quality of life for patients with spine involvement.

Abstract
OBJECTIVE Spinal ganglioneuromas (GNs) are rare benign tumors that often manifest as symptoms related to the compression of neural elements. The preferred treatment for affected patients is surgical resection, which typically improves symptoms and accompanies a low likelihood of tumor recurrence. We conducted a systematic review of reports of GNs involving the spinal cord and nerve roots, examining their clinical presentation, surgical management, and outcomes. METHODS Using the keywords "ganglioneuroma" and "spinal," we conducted a systematic database review of MEDLINE (PubMed), Scopus, and Embase, querying studies reporting cases of spinal GNs. Patients' demographics, location of the tumors, clinical features, and surgical outcomes were extracted from eligible articles. RESULTS A total of 93 spinal GN cases in 52 case reports/series met our criteria. Data analysis revealed a general male predominance, though thoracic spinal GNs were seen more in females. The mean age of patients with cervical, thoracic, thoracolumbar, and lumbar spinal GNs were 41.28, 27.65, 15.61, and 38.73 years, respectively. Multiple-level GNs were mostly seen in male patients or individuals with neurofibromatosis type 1. In all but 1 case, recurrence and reoperation were not reported in the short-term (months) and long-term (2-10 years) follow-up. CONCLUSIONS We found unique epidemiologic characteristics for patients with GNs of different spinal regions. The treatment of choice is achieving gross total resection, but given the eloquency of the lesions, achieving decompression via subtotal resection can also be associated with improved outcomes. To date, no global postoperative surveillance protocol exists, considering the low recurrence rate and relevant cost-benefit ratios.

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
INTRODUCTION Intramedullary spinal cord tumors (IMSCTs) account for 2-4% of all primary CNS tumors. Given their low prevalence and the intricacy of their diagnosis and management, it is critical to address the surrounding racial and socioeconomic factors that impact the care of patients with IMSCTs. This study aimed to investigate the association between race and socioeconomic factors with overall 5 year mortality following the resection of IMSCTs. METHODS The study used the National Cancer Database to retrospectively analyze patients who underwent resection of IMSCTs from 2004 to 2017. Patients were divided into four cohorts by race/ethnicity, facility type, insurance, median income quartiles, and living area. The primary outcome of interest was 5 year survival, and secondary outcomes included postoperative length of stay and 30 day readmission. Descriptive and multivariable analyses were used to identify independent factors associated with mortality, with statistical significance assessed at a 2-sided p < 0.05. RESULTS We evaluated the patient characteristics and outcomes for 8,028 patients who underwent surgical treatment for IMSCTs between 2004 and 2017. Most patients were white males (52.4%) with a mean age of 44 years where 7.17% of patients were Black, 7.6% were Hispanic, and 3% were Asian. Most were treated in an academic/research program (72.4%) and had private insurance (69.2%). Black patients had a higher odd of 5 year mortality (OR 1.4; 95% CI 1.1 to 1.77; p = 0.04) compared to white patients, while no significant differences in mortality were observed among other races. Factors associated with lower odds of mortality included being female (OR 0.89; 95% CI 0.78 to 1.02; p < 0.01), receiving treatment in an academic/research program (OR 0.51; 95% CI 0.33 to 0.79; p = 0.04), having private insurance (OR 0.65; 95% CI 0.45 to 0.93; p = 0.02), and having higher income quartiles (OR 0.77; 95% CI 0.62 to 0.96; p = 0.02). CONCLUSION Our study sheds light on the healthcare disparities that exist in the surgical management of IMSCTs. Our findings indicate that race, sex, socioeconomic status, and treatment facility are independent predictors of 5 year mortality, with Black patients, males, those with lower socioeconomic status, and those treated at non-academic centers experiencing significantly higher mortality rates. These alarming disparities underscore the urgent need for policymakers and researchers to address the underlying factors contributing to these discrepancies and provide equal access to high-quality surgical care for patients with IMSCTs.

Abstract
Diffusion weighted imaging (DWI) has developed into a powerful tool for the evaluation of spine tumors, particularly for the assessment of vertebral marrow lesions and intramedullary tumors. Advances in magnetic resonance techniques have improved the quality of spine DWI and diffusion tensor imaging (DTI) in recent years, with increased reproducibility and utilization. DTI, with quantitative parameters such as fractional anisotropy and qualitative visual assessment of nerve fiber tracts, can play a valuable role in the evaluation and surgical planning of spinal cord tumors. These widely available techniques can be used to enhance the diagnostic evaluation of spinal tumors.

Abstract
Spinal cord tumors are best identified by conventional MR imaging with contrast. Most intramedullary spinal cord tumors have characteristic MR imaging features that allow an accurate preoperative diagnosis. The spinal cord tumors reviewed in this article include the most common tumors, ependymomas and astrocytomas, as well as the less common tumors such as hemangioblastomas and metastases. Rare tumors such as primary CNS lymphoma and melanocytic tumors are also described. Advanced imaging techqniques of more common intramedullary tumors are also reviewed.

Abstract
The spinal cord is a conduit within the central nervous system (CNS) that provides ongoing communication between the brain and the rest of the body, conveying complex sensory and motor information necessary for safety, movement, reflexes, and optimization of autonomic function. After a traumatic spinal cord injury (SCI), supraspinal influences on the peripheral nervous system and autonomic nervous system (ANS) are disrupted, leading to spastic paralysis, sympathetic blunting, and parasympathetic dominance, resulting in cardiac dysrhythmias, systemic hypotension, bronchoconstriction, copious respiratory secretions, and uncontrolled bowel, bladder, and sexual dysfunction. This article outlines the pathophysiology of the less reported nontraumatic SCI (NTSCI), its classification, its influence on sensory/motor function, and introduces the probable comorbidities associated with SCI that will be discussed in more detail in the accompanying manuscripts of this special issue. Finally, management strategies for NTSCI will be provided.

Abstract
Acute Flaccid Myelitis is defined by the presence of Acute Flaccid Paralysis (AFP) and a spinal cord lesion on magnetic resonance imaging that is primarily limited to the grey matter. AFM is a difficult situation to deal with when you have a neurologic illness. According to the Centers for Disease Control and Prevention (CDC), a large number of cases were discovered in the United States in 2014, with 90% of cases occurring in children. Although the exact cause of AFM is unknown, mounting evidence suggests a link between AFM and enterovirus D68 (EV-D68). In 2014, an outbreak of AFM was discovered in the United States. The condition was initially linked to polioviruses; however, it was later found that the viruses were caused by non-polioviruses Enteroviruses D-68 (EV-D68). The number of cases has increased since 2014, and the disease has been declared pandemic in the United States. The sudden onset of muscle weakness, usually in an arm or leg, as well as pain throughout the body, the change in patient's facial expression (facial weakness), and shortness of breath, ingesting, and speaking are all common symptoms in patients suffering from neurologic disease. This article includes graphic and histogram representations of reported AFM incidents and criteria for causality, epidemiology, various diagnostic approaches, signs and symptoms, and various investigational guidelines. It also includes key statements about recent clinical findings related to AFM disease.

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
We present the case of a 29-year-old patient whose pain began with the interscapular region, progressing to paresthesia and loss of muscle strength in the lower extremities. MRI of the spine was done, a lesion was found in T2 to T6, ependymoma was suspected and was taken to subtotal resection with laminectomy, the histopathological report, as well as the immunohistochemistry, was compatible with glioblastoma type not otherwise specified (NOS). He received adjuvant with radiotherapy and concomitant chemotherapy, but he progressed to the cervical and lumbar spine, the patient died 16 months after diagnosis. A review of the literature is made and the clinical and radiological characteristics and treatment protocols that have been used in this entity are reported.

Abstract
Background: Intramedullary spinal masses is a rare yet devastating and challenging. One of the biggest difficulty is to reveal the mass type and feature, thus determine the definitive treatment. Despite its difficulties, many controversies persist regarding diagnosis and management.
Case Presentation: We report a case of 6 years old female came with gradual right limb weakness for 1 week before admission. It preceded by neck stiffness and for 2 weeks ago. Radiological examination revealed intradural intramedullary mass suggesting a cavernoma at VC1-C2 and VTh12-L1 level. The histopathological results shows unspecified hematoma.
Conclusions: Intramedullary tumors in pediatric population is rare and can mimic any other mass lesion. MRI is the mainstay diagnostic tool of this patient. Complete surgical resection is the main goal of treatment, but the histopathologic features is the most important predictor of the functional outcome.

Primary Intradural Extramedullary Sporadic Spinal Hemangioblastomas: Case Report and Systematic Review. World Neurosurg 2021; 152:84-94. [PMID: 34087464 DOI: 10.1016/j.wneu.2021.05.105] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 05/22/2021] [Accepted: 05/24/2021] [Indexed: 11/21/2022]
Abstract
BACKGROUND Hemangioblastomas are benign vascular neoplasms of the central nervous system that may occur sporadically or in association with Von Hippel-Lindau disease. A minority of these lesions can occur in the spine, mostly as intramedullary masses. The authors present a rare case of primary sporadic spinal hemangioblastoma occurring as an intradural extramedullary (IDEM) lesion. Diagnostic workup and surgical management of the patient are described. METHODS A systematic MEDLINE search was conducted using the keywords "hemangioblastoma" and "intradural extramedullary," "extramedullary," or "cauda equina." Clinicopathological characteristics and outcomes of the present case were reviewed and compared with those in the literature. RESULTS A 72-year-old man was found to have an IDEM lesion in his cervical spine after presenting with neck and shoulder pain. Gross total resection was successfully performed with sacrifice of an involved dorsal nerve rootlet. Screening for Von Hippel-Lindau was negative. Thirty-three additional patients with sporadic IDEM hemangioblastomas are reported in the literature. There was a slight male preponderance (54%) with a median age of 52 years. Patients presented with pain (54%), radiculopathy (33%), or myelopathy (32%). The majority of lesions were located in the lumbosacral spine (56%). All patients underwent maximal safe resection with stable or improved clinical status. CONCLUSION Primary IDEM hemangioblastomas are a rare entity. Differential diagnosis includes other IDEM lesions, such as schwannomas, meningiomas, or some vascular malformations. Resection of these sporadic tumors can be safely performed and result in improvement of neurologic deficits associated with mass effect from the tumor with low likelihood of recurrence.

Abstract
Diffuse midline glioma with histone H3 lysine27-to-methionine mutation (H3 K27M mutation) is a rare, aggressive tumor that is designated as World Health Organization (WHO) grade IV regardless of histologic features. Preoperative diagnosis remains challenging due to limited evidence regarding distinctive clinical and imaging characteristics. We describe the case of a young woman who presented with progressively worsening headaches due to communicating hydrocephalus. MR imaging with contrast of the cervical and thoracic spine revealed diffuse leptomeningeal enhancement with focal areas of intramedullary and subarachnoid T2 hyperintensity and enhancement, suggestive of a potential infectious process. Intraoperatively, no epidural pathology was identified, and with the differential diagnosis remaining broad, a second procedure was conducted involving intradural exploration and biopsy of a lesion. This was then identified as a diffuse midline glioma with H3 K27M mutation. The nonfocal clinical presentation in the setting of communicating hydrocephalus as well as the significant exophytic tumor growth and imaging findings made the initial diagnosis unique and challenging. This case, therefore, emphasizes the rare presentation of this tumor, and the need for further understanding of the clinical and imaging characteristics of this disease as well as the need for effective therapeutics.

Abstract
Pilocytic spinal cord astrocytomas make up 21% of intramedullary tumors. Only 20% of those tumors are associated with syringomyelia. To our knowledge, this is the first report of an adult presenting with multiple spinal pilocytic astrocytomas associated with syringomyelia. We report a case of a 27-year-old woman who had neck and arm pain for months. She underwent cervical magnetic resonance imaging (MRI) that demonstrated a syrinx from C2 and extending to C6. A coronal view of the MRI showed multiple mural nodules. Total excision of multicentric nodules within a cyst was performed with an uneventful intraoperative and postoperative period and the patient was discharged home with moderate right-hand numbness.

Abstract
PURPOSE OF REVIEW This article reviews the current classification system of primary spinal cord tumors and explores evolving diagnostic and therapeutic strategies for both primary tumors and metastatic tumors to various compartments of the spinal cord. RECENT FINDINGS The 2016 World Health Organization classification system allows for more precise prognostication of and therapy for spinal cord tumors and has identified new entities, such as the diffuse midline glioma, H3 K27M mutant. Whole-exome sequencing reveals that the genetic background of primary glial spinal cord neoplasms differs from that of their intracranial histologic counterparts in ways that can potentially influence therapy. Targeted and immune checkpoint therapies have improved survival for patients with melanoma and lung cancer and have simultaneously produced novel complications by enhancing radiation toxicity in some cases and by facilitating the emergence of novel autoimmune and paraneoplastic syndromes involving the spinal cord, such as neuromyelitis optica spectrum disorder and syndromes associated with anti-Hu and collapsin response mediator protein-5 (CRMP-5) antibodies. These conditions must be distinguished from tumor or infection. Epidural spinal cord compression treatment paradigms have changed with the advent of robotic surgery and advances in radiation therapy. SUMMARY Neoplastic myelopathies subsume a wide spectrum of pathologies. Neoplastic cord involvement may be primary or secondary and may be approached diagnostically by the particular spinal cord compartment localization. Primary spinal cord tumors account for only 2% to 4% of primary central nervous system tumors, ranging from low-grade glial neoplasms to malignant tumors. Metastatic malignancy to the epidural or leptomeningeal spaces is more common than primary cord tumors. Differential diagnoses arising in the course of evaluation for cord tumors include myelopathies related to radiation or chemotherapy and paraneoplastic syndromes, all of which are sources of significant morbidity. Knowledge of genetic syndromes and the biologic behavior of diverse histologies together with selective application of surgery, radiation, and targeted therapies can facilitate diagnosis, minimize surgical morbidity, and prolong quality of life.

Abstract
Spinal tumors pose significant treatment challenges for the physicians treating them. Understanding the location of the tumor within the intramedullary, intradural extramedullary, or extradural (epidural) space is not only critical in determining a differential diagnosis but may also provide important information about current and future neurologic deficits. Despite significant advances in the treatment of spinal tumors over the past few decades, these patients may still experience significant symptoms related to the tumor or its treatment, such as pain, weakness, impaired sensation, and bowel and bladder dysfunction. Treatment of spinal tumors should involve a multidisciplinary team of neuro-oncologists, spine surgeons, medical and radiation oncologists, physiatrists, and pain specialists to provide comprehensive oncologic management, while optimizing the patient's functional status and quality of life.

Abstract
Context: Approximately 25% of all primary spinal cord tumors are meningiomas, and 80% of these tumors occur in the thoracic region. Few meningiomas of the lumbar spine have been presented. Extracranial metastasis of meningioma occurs extremely rare, only in about 0.1% of meningiomas. Even metastasis, the sites are seldom seen in deep soft tissue. We reported a woman original meningioma in the lumbar spine with distal deep neck metastasis. Findings: A 59-year-old patient suffered from severe right drop foot, numbness, and radicular pain for the previous 6 months. Computed tomography (CT) disclosed a huge, macrolobulated retroperitoneal soft-tissue lesion with a size of 14.9 × 10.8 × 17.7 cm. Magnetic resonance imaging (MRI) further revealed a solid spinal intracanal tumor with moderate enhancement involving the right paraspinal region at the L2∼L5 level and the right iliac fossa. A meningioma was diagnosed with histological proof. Four months later, another metastatic meningioma in her left neck. She was managed conservatively without neurologic dysfunction. Conclusions: To the best of our knowledge, such a large meningioma of the lumbar spine has not previously been reported in the literature. In this study, we demonstrated a rare spinal meningioma located in the lumbar spine primarily with secondary soft tissue metastasis.

Abstract
BACKGROUND Melanocytic lesions of the nervous system are thought to arise from leptomeningeal melanocytes, which are derived from neural crest and include diffuse melanocytosis, melanocytomas, and malignant melanomas. Meningeal melanocytomas are extremely rare benign lesions. The usual treatment of intradural extramedullary melanocytomas involves surgical removal through a posterior approach using a laminectomy or laminotomy. CASE DESCRIPTION We present a 30-year-old female harboring a C6-T1 ventrally located intradural extramedullary lesion compressing the cord anteriorly. The lesion was totally resected via an anterior approach with oblique corpectomy even if the usual treatment involves surgical removal through a posterior approach using a laminectomy or laminotomy. CONCLUSIONS There is no evidence of recurrence at 4-year follow-up records of the patient. We discuss the surgical approach of these rare lesions.

Abstract
Context: Venous thromboembolism (VTE), including deep-vein thrombosis (DVT) and pulmonary embolism (PE), is the fatal complication following spine surgery and the appropriate perioperative prophylaxis is still debated. Aims: The aim of this study is to evaluate the incidence of along with risk factors for postoperative VTE in surgically treated extramedullary spinal tumor patients. Setting and Designs: The study design involves single institute and retrospective cohort study. Subjects and Methods: The cohort database was reviewed between the periods of January 2014 and June 2019. Patients undergoing surgery for spine tumor, extradural tumor, and intradural extramedullary were consecutively collected. Statistical Analysis Used: The incidence of VTE and clinical factors reported to be associated with VTE were identified, and then analyzed with an appropriate Cox regression model. Results: The study identified 103 extramedullary spinal tumor patients. Three patients (2.9%) were diagnosed with a proximal leg DVT, while symptomatic PE did not identify. Risk factors associated with DVT occurrence were as follows: operative time ≥8 h (Hazard ratio [HR] 13.98, P = 0.03) and plasma transfusion (HR 16.38, P = 0.02), whereas plasma transfusion was the only significant factor, after multivariate analysis (HR 11.77, P = 0.05). Conclusions: Patients who underwent surgery for extramedullary spinal tumors showed a 2.9% incidence of DVT. The highest rate of DVT was found in patients who received plasma transfusion. More attention should be paid on perioperative associated factors for intensive prevention coupled with early screening in this group.

Abstract
Objective: Intramedullary spinal cord tumors (IMSCT) are rare entities and high-level evidence regarding optimal treatment is lacking. We aim to describe the demographics, histopathological distribution, onset symptoms, treatment strategies, and functional outcome for patients surgically treated for IMSCT. Methods: We performed a retrospective review of a consecutive population-based cohort of 95 patients who underwent surgery for intra- or juxtamedullary tumors at a single institution during the period 2004–2017. Results: When gross total resection (GTR) was achieved, we found no case of local tumor recurrence even in the absence of adjuvant radio- or chemotherapy. Meanwhile, we found a 50% progression rate on long-term MRI follow-up in patients where only a partial resection was possible. At long-term follow-up, there was no significant alteration in functional status, while a significant reduction in share of patients reporting pain, compared to preoperative status, was identified. Poor preoperative functional status and postoperative tumor remnant were identified as individual risk factors for further functional decline. Conclusion: Gross total resection, with minimal post-operative neurological deterioration, is possible in the majority of the cases, especially in the presence of an identifiable resection plane between tumor and healthy spinal cord. Since long-term progression-free survival could be achieved by GTR without additional adjuvant treatment, we emphasize that low-grade tumors should not be subject to radiotherapy. Treatment of high-grade or diffusely infiltrating tumors, tumor remnants, or metastases should be individualized.

Abstract
Objective: We report a child presenting with spinal myelopathy secondary to H3K27M mutant diffuse
midline glioma. Case Report: A 4-year-old boy presented with a 3-week history of progressive gait difficulty.
Examination revealed bilateral hand and lower extremity weakness, left leg hypertonia
with ankle clonus, and a right hemisensory deficit. Magnetic resonance imaging of
neuroaxis showed cervical and thoracic spinal cord with expansion and irregular areas of
enhancement. Serum and cerebrospinal fluid studies were unremarkable for infectious,
autoimmune, inflammatory, and neoplastic causes but showed mild cerebrospinal fluid
pleocytosis, hypoglycorrhachia, and high protein level. A thoracic cord biopsy revealed
a diffuse midline glioma (World Health Organization grade IV). Consequently, the tumor
involved intracranial structures and patient died within 4 months after diagnosis. Conclusion: High-grade spinal cord gliomas are very rare but should be considered in the
differential diagnosis of pediatric myelopathy. Tissue biopsy is recommended in
indeterminate cases to facilitate diagnosis and to guide management.

Abstract
Spinal cord tumors (SCT) are uncommon neoplasms characterized by irregular growth of tissue inside the spinal cord that can result in non-mechanical back pain. Current treatments for SCT include surgery, radiation therapy, and chemotherapy, but these conventional therapies have many limitations. Suicide gene therapy using plasmid encoding herpes simplex virus-thymidine kinase (pHSV-TK) and ganciclovir (GCV) has been an alternative approach to overcome the limitations of current therapies. However, there is a need to develop a carrier that can deliver both pHSV-TK and GCV for improving therapeutic efficacy. Our group developed a cationic, amphiphilic copolymer, poly (lactide-co-glycolide) -graft-polyethylenimine (PgP), and demonstrated its efficacy as a drug and gene carrier in both cell culture studies and animal models. In this study, we evaluated PgP as a gene carrier and demonstrate that PgP can efficiently deliver reporter genes, pGFP in rat glioma (C6) cells in vitro, and pβ-gal in a rat T5 SCT model in vivo. We also show that PgP/pHSV-TK with GCV treatment showed significantly higher anticancer activity in C6 cells compared to PgP/pHSV-TK without GCV treatment. Finally, we demonstrate that PgP/pHSV-TK with GCV treatment increases the suicide effect and apoptosis of tumor cells and reduces tumor size in a rat T5 SCT model.

Abstract
Spinal cord astrocytomas are rare diseases of the central nervous system. The localization of these tumors and their infiltrative growth complicate their surgical resection, increase the risk of postoperative complications, and require more careful use of radio- and chemotherapy. The information on the genetic mutations associated with the onset and development of astrocytomas provides a more accurate neoplasm diagnosis and classification. In some cases, it also allows one to determine the optimal methods for treating the neoplasm, as well as to predict the treatment outcomes and the risks of relapse. To date, a number of molecular markers that are associated with brain astrocytomas and possess prognostic value have been identified and described. Due to the significantly lower incidence of spinal cord astrocytomas, the data on similar markers are much more sparse and are presented with a lesser degree of systematization. However, due to the retrospective studies of clinical material that have been actively conducted abroad in recent years, the formation of statistically significant genetic landscapes for various types of tumors, including intradural spinal cord tumors, has begun. In this regard, the purpose of this review is to analyze and systematize the information on the most significant genetic mutations associated with various types of astrocytomas, as well as discuss the prospects for using the corresponding molecular markers for diagnostic and prognostic purposes.

Abstract
BACKGROUND With the aging population in the United States, it can be anticipated that the prevalence of spinal cord injuries (SCIs) and cancer will increase. Primary or metastatic spine tumors sit at a unique intersection of these 2 realms. Our objective was to evaluate the prevalence, outcomes, and complications after the management of SCI arising from spinal tumors. METHODS In the present retrospective evaluation, all patients with SCI and a diagnosis of primary or metastatic spinal cancer who had been admitted to the inpatient rehabilitation unit at a level 1 trauma center from January 2003 to January 2014 were evaluated. The demographic data (age, sex, race/ethnicity), tumor characteristics, American Spinal Injury Association score, and complications were evaluated. RESULTS A total of 757 SCI entries were identified, and 685 unique patients met our inclusion criteria. Of those, 81 had SCIs due to spinal tumors (11.8% of all SCIs and 19.2% of nontraumatic SCIs). Most tumors were located in the thoracic region (65.4%) and were primary central nervous system in origin (21.0%), including meningioma (7.4%), schwannoma (3.7%), and ependymoma (2.5%). The next most common origins of the spinal tumors were metastases from the lung (17.3%), prostate (9.9%), kidney (8.6%), lymphoma (7.4%), and multiple myeloma (7.4%). Of these patients, 76.5% underwent surgical management, with a complications rate of 61.3%. The overall mortality rate at the latest follow-up examination was 63.0%. CONCLUSIONS SCI associated with spinal tumor is often managed surgically and associated with high rates of complications. The present study has demonstrated longer survival rates compared with the existing data.

Abstract
BACKGROUND In a developing country there is a need for development of criteria that can be used for the diagnosis of spinal tuberculosis, which is common in that region. METHODS Demographic, clinical, and radiologic features of spinal tuberculosis and spinal epidural tumors have been compared statistically, and inferences have been drawn in terms of P values, sensitivity, specificity, positive predictive values, and negative predictive values. RESULTS A statistically significant relationship was found between spinal tuberculosis and spinal pain, fever, gradually progressive lower limb weakness, contrast-enhancing epidural ± paravertebral lesions, continuous levels affected, spinal deformity, and raised erythrocyte sedimentation rate. CONCLUSIONS These relationships were considered the most probable criteria for the diagnosis of spinal tuberculosis.

Abstract
The aim of the present study was to investigate the risk factors for postoperative recurrence of spinal tumors by logistic regression analysis and analysis of prognostic factors. In total, 77 male and 48 female patients with spinal tumor were selected in our hospital from January, 2010 to December, 2015 and divided into the benign (n=76) and malignant groups (n=49). All the patients underwent microsurgical resection of spinal tumors and were reviewed regularly 3 months after operation. The McCormick grading system was used to evaluate the postoperative spinal cord function. Data were subjected to statistical analysis. Of the 125 cases, 63 cases showed improvement after operation, 50 cases were stable, and deterioration was found in 12 cases. The improvement rate of patients with cervical spine tumor, which reached 56.3%, was the highest. Fifty-two cases of sensory disturbance, 34 cases of pain, 30 cases of inability to exercise, 26 cases of ataxia, and 12 cases of sphincter disorders were found after operation. Seventy-two cases (57.6%) underwent total resection, 18 cases (14.4%) received subtotal resection, 23 cases (18.4%) received partial resection, and 12 cases (9.6%) were only treated with biopsy/decompression. Postoperative recurrence was found in 57 cases (45.6%). The mean recurrence time of patients in the malignant group was 27.49±6.09 months, and the mean recurrence time of patients in the benign group was 40.62±4.34. The results were significantly different (P<0.001). Recurrence was found in 18 cases of the benign group and 39 cases of the malignant group, and results were significantly different (P<0.001). Tumor recurrence was shorter in patients with a higher McCormick grade (P<0.001). Recurrence was found in 13 patients with resection and all the patients with partial resection or biopsy/decompression. The results were significantly different (P<0.001). Logistic regression analysis of total resection-related factors showed that total resection should be the preferred treatment for patients with benign tumors, thoracic and lumbosacral tumors, and lower McCormick grade, as well as patients without syringomyelia and intramedullary tumors. Logistic regression analysis of recurrence-related factors revealed that the recurrence rate was relatively higher in patients with malignant, cervical, thoracic and lumbosacral, intramedullary tumors, and higher McCormick grade and patient received partial resection or biopsy. Tumor property, tumor location, McCormick grade, tumor resection, and intramedullary tumors are risk factors for the recurrence of spinal tumors. Clinical assessment of these risk factors may be helpful in selecting appropriate treatment strategies.

Abstract
RATIONALE Primary spinal glioblastoma multiforme (GBM) is a rare clinical entity with an aggressive course and an invariably dismal prognosis. Its clinical characteristics, radiologic and pathologic findings, and treatment protocols have been discussed in a few cases. PATIENT CONCERNS A 15-year-old female was admitted to the neurology department with a chief complaint of progressive numbness and weakness in her left upper extremity for 3 months and neck pain for 1 month. DIAGNOSES Spinal magnetic resonance imaging showed an intramedullary expansile mass localized between C4 and C7. The diagnosis of GBM was determined on the basis of the histopathological findings after operation. INTERVENTIONS Laminotomy and laminoplasty between C4 and C7 were performed, and the tumor was partially resected. The patient was administered focal adjuvant radiotherapy concomitantly with oral chemotherapy following the surgery. OUTCOMES With severe neurologic deficits at 13 months after the diagnosis, the patient expired. LESSONS Although therapeutic options have been improving, the prognosis of the primary spinal GBM remains poor. The treatment of primary spinal GBM entered into a central registry and multiple-center cooperation is important in establishing future therapeutic strategies.

Abstract
STUDY DESIGN The expression of HOXB13 and HOXA9 proteins was detected. OBJECTIVE The purpose of this study was to investigate the molecular signature of spinal ependymoma (EPN) and astrocytoma, 2 most common types of intramedullary spinal tumor. SUMMARY OF BACKGROUND DATA Intramedullary spinal tumor is unusual. It leads to high neurological morbidity and mortality without treatment. Till now, its molecular feature has been elucidated up to a little extent. METHODS A total of 37 cases of spinal EPN, including 12 myxopapillary EPNs (MEPNs), 18 classic EPNs, and 7 anaplastic EPNs, and another 12 cases of astrocytoma were selected for this study. Immunohistochemical analysis of a large cohort of patients providing clinical tumor samples was performed to compare the expression of HOXB13 and HOXA9 not only between spinal EPN and astrocytoma but also among all 3 World Health Organization grades of spinal EPN. RESULTS The results showed that HOXB13 and HOXA9 were selectively expressed in spinal EPN instead of astrocytoma. Furthermore, we found the strongest positive response of HOXB13 in MEPN whereas that of HOXA9 was ubiquitously detected in all subgroups of EPN. CONCLUSION Both specificity and sensitivity of HOXB13 in MEPN indicated that HOXB13 might be a diagnostic marker to distinguish MEPN from other 2 types of EPN and a promising therapeutic target for MEPN. The strong immunoreactivity of HOXA9 in spinal EPN suggested an indispensable role in the progression of spinal EPN, and further research on its molecular function will provide new clues for the development of treatment options.

Abstract
Weakness and numbness occur in a variety of patterns that reflect injury to different parts of the central and peripheral nervous system. Progressive symptoms most often signify an underlying structural or degenerative problem. Familiarity with the major descending motor and ascending sensory tracts of the central nervous system, as well as radicular (dermatome and myotome) and peripheral nerve anatomy, is essential. Damage to these tracts and nerve fibers produces characteristic clinical symptoms and signs. Imaging, when used in a hypothesis-driven way, can be a valuable adjunct to the clinical history and physical examination. One of the most useful aspects of imaging is that it allows for differentiation of edema and inflammation from gliosis and atrophy, both of which can be associated with progressive weakness or numbness. Compression of nervous system structures by nonnervous system tissue can also be easily detected. The spectrum of diseases and imaging abnormalities associated with progressive weakness and numbness is highlighted in this review via a series of illustrative cases. In each case, anatomic localization and the key imaging findings are emphasized.

Abstract
Myelopathy is an inclusive term, referring to pathology leading to a neurologic deficit related to the spinal cord. The clinical diagnosis of myelopathy requires a detailed history and physical examination to define the clinical syndrome. Neuroimaging is indicated in most instances of new-onset myelopathy. It is indicated also when the worsening of a myelopathy is unexplained. Advances in neuroimaging have proved to play a vital role in diagnosis. Appropriate diagnosis and treatment are dependent upon an adequate imaging evaluation to establish the presence of mechanical stability, extrinsic spinal cord compression, or an intramedullary lesion. The most frequent etiology of myelopathy is related to degenerative disease of the spine from osteophyte or extruded disc material causing compression of the spinal cord in the cervical or thoracic spine. The next common etiologies are spinal cord compression due to extradural masses caused by metastatic disease to bone or blunt trauma. In these cases, emergency imaging should be performed to assess the nature of the lesion causing the myelopathy and plan the most appropriate treatment. Also urgent imaging should be performed when an abscess in the spinal canal is suspected. Less urgent is imaging of primary neoplasms of the meninges, roots, or spinal cord, as well as noninfectious inflammatory processes, such as multiple sclerosis, and neurodegenerative, vascular, nutritional, or idiopathic disorders leading to myelopathy. Although a survey of the entire spinal cord can be performed with imaging, it is more appropriate to define from the clinical findings what levels of the spine and spinal cord should be imaged. This approach helps limit the likelihood of false-positive imaging findings that may encourage needless attempts to fix what is not broken. Similarly, the most appropriate imaging study and protocol should be selected in order to provide a timely and accurate diagnosis. To do so requires detailed knowledge regarding the strengths and limitations of the multiple imaging modalities available. This chapter outlines an approach to proper study selection based on the likely etiology of myelopathy from the clinical findings. Chapters 33-39 cover these disorders in detail.

Abstract
OBJECTIVE To evaluate the diffusion tensor imaging (DTI) and diffusion tensor tractography (DTT) features of cervical spinal cord astrocytoma. METHODS Eleven patients with cervical spinal cord astrocytomas and 10 healthy volunteers were recruited in this study. Conventional magnetic resonance imaging (MRI) and axial DTI were performed on a 3.0T MRI system. Apparent diffusion coefficient (ADC), fractional anisotropy (FA), axial diffusivity (AD), and radial diffusivity (RD) values for the lesions were measured. DTT was performed using the principal diffusion direction method. RESULTS ADC values of the lesions and the normal-appearing tissue around the tumour (NATAT) on T2-weighted imaging (T2WI) increased. The ADC values of the lesions were higher. The FA values of the lesions and the NATAT decreased significantly, with the lesions having lower FA values. The RD value (1.36±0.49) of the tumours was significantly higher than those found in the healthy controls, but similar for the AD value (1.84±0.56). There were no differences in ADC or FA values between lesions and NATAT in McCormick Type I vs. Type II patients. Based on the DTT, 7 patients with solid mass tumours were classified as Type I. One patient with a solid mass, 2 patients with cystic degeneration inside the lesions, and 1 patient with a cyst around the mass were classified as Type II. CONCLUSIONS FA values of the cervical spinal cord astrocytoma decreased, but the ADC values increased. DTI was sensitive for the evaluation of pathological changes that could not be visualized on T2WI. Our preliminary study indicates that DTT can be used to guide operation planning, and that axial images of DTT may be more valuable.

Abstract
Primary spinal intradural extramedullary lymphoma remains a very rare entity in spinal oncology. In this case report, we present the first treatment of a PSIEL diagnosed by cytopathologic analysis alone followed by urgent radio- and chemotherapy in the literature. At 18-month follow-up, our patient was ambulatory with near total imaging resolution of the lesion. In conclusion, surgical excision or biopsy may not be necessary when suspicion for PSIEL exists, and may delay prompt medical and radiation treatment due to necessity for wound healing. Further research into the management of extramedullary lymphoma treatment strategies is warranted.

Abstract
Spinal cord tumors are an important component of pathologic diseases involving the spinal cord. Conventional magnetic resonance (MR) imaging only provides anatomical information. MR diffusion tensor imaging (DTI) and MR perfusion-weighted imaging (PWI) may detect microstructure diffusion and hemodynamic changes in these tumors. We review recent application studies of MR DTI and PWI in spinal cord tumors. Overall, MR DTI and MR PWI are promising imaging tools that are especially useful in improving differential diagnosis between spinal cord tumors and tumor mimics, preoperative evaluation of resectability, and providing assistance in surgical navigation.

Abstract
High-grade gliomas of the spinal cord represent a rare entity in children. Their biology, behavior, and controversial treatment options have been discussed in a few pediatric cases. These tumors are associated with severe disability and poor prognosis. We report a case of a 4-year-old child diagnosed with an isolated glioblastoma multiforme of the conus medullaris. The patient underwent subtotal surgical excision, followed by adjuvant radiotherapy and oral chemotherapy. He is alive with mild neurologic deficits at 52 months after diagnosis. We describe the peculiar characteristics of this rare condition in pediatric oncology. We also provide an overview of current multidisciplinary therapeutic approaches and prognostic factors for this disease.

Abstract
We review the anatomy of the spinal cord, providing correlation with key functional and clinically relevant neural pathways, as well as magnetic resonance imaging. Peripherally, the main descending (corticospinal tract) and ascending (gracilis or cuneatus fasciculi and spinothalamic tracts) pathways compose the white matter. Centrally, the gray matter can be divided into multiple laminae. Laminae 1-5 carry sensitive neuron information in the posterior horn, and lamina 9 carries most lower motor neuron information in the anterior horn. Damage to the unilateral corticospinal tract (upper motor neuron information) or gracillis-cuneatus fasciculi (touch and vibration) correlates with ipsilateral clinical findings, whereas damage to unilateral spinothalamic tract (pain-temperature) correlates with contralateral clinical findings. Damage to commissural fibers correlates with a suspended bilateral "girdle" sensory level. Autonomic dysfunction is expected when there is bilateral cord involvement.

Abstract
Spinal paragangliomas (SP) are benign and overall rare extra-adrenal neuroendocrine tumors often diagnosed during workup for lower back pain. Complete surgical resection achieves both symptomatic relief and cure. We present a 32-year-old man with a longstanding history of lumbago and bilateral lower extremity pain found to have a lumbar paraganglioma at the level of the L3 vertebrae. The clinical, histopathological, and radiological characteristics are described, including the rare finding of superficial siderosis on MRI of the brain. A laminectomy with microscopic dissection of the intradural mass achieved complete debulking without evidence of residual tumor. Excellent prognosis can be achieved with complete surgical resection of SP without the need for adjuvant therapy. Therefore, care should be taken to distinguish these spinal tumors from those that appear similar but are more aggressive. As such, the radiological finding of superficial siderosis should raise the suspicion for SP when a vascular intradural extramedullary spinal tumor is observed.

Molecular and clinical prognostic factors for favorable outcome following surgical resection of adult intramedullary spinal cord astrocytomas. Clin Neurol Neurosurg 2016; 144:82-7. [PMID: 26999530 DOI: 10.1016/j.clineuro.2016.03.009] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2016] [Revised: 03/10/2016] [Accepted: 03/12/2016] [Indexed: 11/25/2022]
Abstract
OBJECTIVE Intramedullary spinal cord astrocytomas are uncommon but important entities. Aggressive surgical resection is believed to be critical to prevent subsequent neurological deterioration; however, the prognostic significance of numerous patient and molecular variables remains unclear. We sought to investigate the clinical and molecular factors associated with outcomes following surgical resection of adult spinal cord astrocytomas. METHODS A consecutive retrospective chart review of all patients who underwent intramedullary spinal cord astrocytoma resection at a single tertiary-care institution between January 1996 and December 2011 was conducted. Molecular data collected included p53 mutation status, proliferative activity (Ki-67), 1p/19q chromosome loss, and EGFR amplification. Multivariable logistic and Cox proportional hazards regression were used to identify variable associated with postoperative outcomes. RESULTS Among 13 patients undergoing surgical resection followed for a median of 54 months, 54% experienced improvement in neurological status, while 15% remained unchanged and 31% deteriorated. Following resection, the 5-year local control (LC), progression-free survival (PFS), and overall survival (OS) rates were 83%, 63%, and 83%. Median PFS time was found to be 5.6 years. Multivariable regression revealed limited characteristics associated with postoperative outcomes, though no molecular characteristics were found to be prognostic. Older age at surgery predicted decreased probability of PFS (HR 0.91, 95% CI 0.81-0.99, p=0.03) and trended towards predicting lack of neurological improvement (OR 0.94, 95% CI 0.83-1.02, p=0.21) and decreased OS (HR 0.93, 95% CI 0.81, 1.03, p=0.15). Preoperative motor symptoms (OR 0.12, 95% CI <0.01-1.91, p=0.14) and adjuvant chemotherapy (OR 0.07, 95% CI <0.01-1.82, p=0.12) also trended towards predicting lack of neurological improvement. CONCLUSION Age was the only patient variable found to have a statistically significant association with profession-free survival and no other factors were significantly associated with postoperative outcomes. These findings were limited by a relatively small sample size; thus, future studies with increased power investigating the prognostic effects of molecular characteristics could provide further clarity in identifying patients most likely to benefit from surgical resection.
