Abstract
At some institutions, musculoskeletal and general radiologists rather than neuroradiologists are responsible for reading magnetic resonance imaging (MRI) of the spine. However, neurological findings, especially intrathecal ones, can be challenging. Intrathecal neurological findings in the spine can be classified by location (epidural, intradural extramedullary, and intramedullary) or etiology (tumor, infection, inflammatory, congenital). In this paper, we provide a succinct review of the intrathecal neurological findings that can be seen on MRI of the spine, primarily by location and secondarily by etiology, in order that this may serve as a helpful guide for musculoskeletal and general radiologists when encountering intrathecal neurological pathologies.

Abstract
Intramedullary spinal cord metastases (ISCM) are a rare and challenging manifestation of metastatic cancer that have devastating impacts on the individual's neurological function, survival expectancy and overall quality of life. Given the rarity and poor prognosis, there is a lack of consensus in management. Uterine carcinosarcoma itself is a rare cancer, accounting for less than 3% of all uterine cancers. It carries a poor prognosis, with only one-third of patients surviving beyond 5 years. There are no previous reports of uterine carcinosarcoma metastases to the spinal cord. Here, we present the case of a woman in her late 70s with a uterine carcinosarcoma intramedullary metastasis that was refractory to radiotherapy treatment and responded favourably to surgical debulking.

Abstract
Objective Animal models of brain and spinal cord metastases of non-small cell lung cancer were established through the intracranial injection of PC-9 Luc cells with a brain stereotaxic device. This method provides a reliable modeling method for studying brain and spinal cord metastases of non-small cell lung cancer. Methods PC-9 Luc cells at logarithmic growth stage were injected into the skulls of 5-week-old BALB/c nude mice at different cell volumes (30 × 104, 80 × 104) and different locations (using anterior fontanel as a location point, 1 mm from the coronal suture, and 1.5 mm from the sagittal suture on the right upper and right lower side of the skull). After 1 week of cell inoculation, fluorescence signals of tumor cells in the brain and spinal were detected using the IVIS Xenogen Imaging system. After 4 weeks, brain and spinal tissues from the nude mice were harvested. Following paraffin-embedded sectioning, HE staining was performed on the tissues. Results The fluorescence signals revealed that both brain and spinal cord metastasis occurred in the mice where the cells were injected at the lower right side of the skull. There was only brain metastasis in the nude mice injected with 30 × 104 cells at the upper right side of the skull. Both brain and spinal cord metastasis occurred in the nude mice injected with 80 × 104 cells. The HE staining revealed that both brain and spinal cord metastasis occurred in the mice injected with different amounts of PC-9 Luc cells, consistent with the results detected using the IVIS Xenogen Imaging system, thereby demonstrating the reliability of detecting fluorescent signals in vivo to determine tumor growth. Conclusion It is a reliable method to establish the animal model of brain and spinal cord metastases of non-small cell lung cancer by injecting different quantities of cells from different positions with a brain stereotaxic device. The IVIS Xenogen Imaging system has high reliability in detecting the fluorescence signals of brain and spinal cord metastatic tumors.

Survival and neurological outcomes following management of intramedullary spinal metastasis patients: a case series with comprehensive review of the literature. Neurosurg Rev 2024; 47:75. [PMID: 38319484 DOI: 10.1007/s10143-024-02308-0] [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: 12/03/2023] [Revised: 01/12/2024] [Accepted: 01/20/2024] [Indexed: 02/07/2024]
Abstract
Intramedullary spinal cord metastasis (ISCM), though rare, represents a potentially debilitating manifestation of systemic cancer. With emerging advances in cancer care, ISCMs are increasingly being encountered in clinical practice. Herein, we describe one of the larger retrospective single institutional case series on ISCMs, analyze survival and treatment outcomes, and review the literature. All surgically evaluated ISCMs at our institution between 2005 and 2023 were retrospectively reviewed. Demographics, tumor features, treatment, and clinical outcome characteristics were collected. Neurological function was quantified via the Frankel grade and the McCormick score (MCS). The pre- and post-operative Karnofsky performance scores (KPS) were used to assess functional status. Descriptive statistics, univariate analysis, log-rank test, and the Kaplan-Meier survival analysis were performed. A total of 9 patients were included (median age 67 years (range, 26-71); 6 were male). Thoracic and cervical spinal segments were most affected (4 patients each). Six patients (75%) underwent surgical management (1 biopsy and 5 resections), and 3 cases underwent chemoradiation only. Post-operatively, 2 patients had an improvement in their neurological exam with one patient becoming ambulatory after surgery; three patients maintained their neurological exam, and 1 had a decline. There was no statistically significant difference in the pre- and post-operative MCS and median KPS scores in surgically treated patients. Median OS after ISCM diagnosis was 7 months. Absence of brain metastasis, tumor histology (renal and melanoma), cervical/thoracic location, and post-op KPS ≥ 70 showed a trend toward improved overall survival. The incidence of ISCM is increasing, and earlier diagnosis and treatment are considered key for the preservation of neurological function. When patient characteristics are favorable, surgical resection of ISCM can be considered in patients with rapidly progressive neurological deficits. Surgical treatment was not associated with an improvement in overall survival in patients with ISCMs.

Abstract
Although rare, intramedullary spinal cord metastases (ISCMs) are on the rise, most likely due to prolonged survival and improved outcomes as a result of the advances in cancer treatment for cancer patients. While the management of these lesions remains controversial, surgery for ISCM has recently been advocated for selected patients. We performed a retrospective analysis on 30 patients who were surgically treated for intramedullary spinal cord metastases in order to determine a preoperative prognostic scoring system to guide patient selection for surgical interventions. The scoring system was designed to decide between surgery or other therapeutic procedures. The five parameters selected and employed in the assessment system were: 1) patient's general condition, 2) age, 3) primary site of the cancer, 4) number of other extramedullary metastases and 5) severity of neurologic symptoms. Prognosis could not be predicted from a single parameter. These five factors were added together to give a prognostic score between 1 and 10. The average survival period of patients with a prognostic score between 1 and 3 points was 3 months; 11 patients with a score of 4 and 5 points had a mean survival of 7.63 months, while patients with a prognostic score between 6 and 10 was 14.8 months. According to our prognostic scoring system for surgical treatment of ISCM, surgery should be performed in those patients who score above 6 points, while radiotherapy/chemotherapy or palliative care is recommended for those who score between 1 and 3 points. A prognostic score of 4 and 5 represents a grey area where surgeons must use their judgment on whether to intervene either medically or surgically. This scoring system could facilitate decision-making in the management of patients with intramedullary spinal cord metastases.

Impact of surgical treatment for intramedullary spinal cord metastasis on neurological function and survival: A multicenter retrospective study by the Neurospinal Society of Japan. J Clin Neurosci 2023; 117:27-31. [PMID: 37740999 DOI: 10.1016/j.jocn.2023.09.013] [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: 07/19/2023] [Revised: 08/31/2023] [Accepted: 09/16/2023] [Indexed: 09/25/2023]
Abstract
BACKGROUND This retrospective multicenter study aimed to analyze the characteristics and surgical outcomes of intramedullary spinal cord metastasis (ISCM) and to discuss the controversy regarding its surgical indications. METHODS This study included 29 ISCM patients who underwent surgery between 2009 and 2020. Biopsy cases were excluded from analysis. For functional and neurological functional assessments, Karnofsky Performance Status (KPS, %) and modified McCormick Scale (MMS, 5-grade scale) scores were determined before and after surgery. Patients were divided into two groups: a mild-to-moderate disability group with preoperative MMS grades 1 to 3, and a severe disability group with preoperative MMS grades 4 to 5. RESULTS The mean preoperative KPS was 45.9, and the mean duration from symptom onset to surgical intervention was 1 month. The ISCM was located in the cervical spine in 10 cases and the thoracic spine in 19 cases. The access route (myelotomy) for ISCM removal was via the posterior median sulcus in 9 cases and via the posterior lateral sulcus in 11 cases, while others were not recorded. The degree of removal was gross total resection in 20 patients (69%), subtotal resection in 0 patients, and partial removal in 9 patients (31%). No significant complications related to the surgical procedures were recorded. Postoperative adjuvant therapy included radiotherapy in 17 patients (58.6%) and chemotherapy or molecular targeted therapy in 13 patients (44.8%). Pathological findings of ISCM showed that colorectal cancer was the most common in 9 cases, followed by lung cancer in 7, renal cell carcinoma in 5, and breast cancer in 2. Twenty-one of the 29 patients (72.4%) were confirmed to have survived 6 months after surgery: 8 of the 10 patients (80%) in the mild-to-moderate disability group and 13 of the 19 patients (68.4%) in the severe disability group. At 6 months after surgery, 3 of the 8 patients (38%) in the mild-to-moderate group were able to maintain or improve their function. Eleven of the 13 patients (85%) in the severe disability group maintained their function despite being severely disabled. CONCLUSIONS This study suggests that surgical treatment can maintain or improve neurological function in a limited number of patients with ISCM, although it had minimal impact on improving the survival rate after surgery.

Abstract
Spinal cord tumors are uncommon, and its multiple representatives not always have pathognomonic characteristics, which poses a challenge for both patients and caring physicians. The radiologist performs an important role in recognizing these tumors, as well as in differentiating between neoplastic and non-neoplastic processes, supporting clinical and surgical decision-making in patients with spinal cord injury. Magnetic Resonance Imaging (MRI) assessment, paired with a deep understanding of the various patterns of cord involvement allied to detailed clinical data can provide a diagnosis or significantly limit the differential diagnosis in most cases. In this article, we aim to review the most common and noteworthy intramedullary and extramedullary spinal tumors, as well as some other tumoral mimics, with an emphasis on their MRI morphologic characteristics.

Abstract
BACKGROUND Intramedullary spinal cord metastasis (ISCM) of malignant tumors rarely happens. To the best of our knowledge, only five cases of ISCM from esophageal cancer have been reported in literature. We here report the sixth descripted case of ISCM from esophageal cancer. CASE PRESENTATION A 68-year-old male presented with weakness of right limbs and localized neck pain two years after diagnosed esophageal squamous cell carcinoma. The gadolinium enhanced Magnetic resonance imaging (MRI) of cervical spine showed a mixed-intense intramedullary tumor with typical more intense thin rim of peripheral enhancement in C4-C5. The patient died fifteen days after diagnosis of irreversible respiratory and circulatory failures. An autopsy was refused by his family. CONCLUSIONS This case highlights the importance of gadolinium enhanced MRI for diagnosis in ISCM. We believe that early diagnosis and surgery for selected patients shows helpfulness to save their neurologic function and improve quality of life.

Abstract
Spinal cord diseases are frequently devastating due to the precipitous and often permanently debilitating nature of the deficits. Spastic or flaccid paraparesis accompanied by dermatomal and myotomal signatures complementary to the incurred deficits facilitates localization of the insult within the cord. However, laboratory studies often employing disease-specific serology, neuroradiology, neurophysiology, and cerebrospinal fluid analysis aid in the etiologic diagnosis. While many spinal cord diseases are reversible and treatable, especially when recognized early, more than ever, neuroscientists are being called to investigate endogenous mechanisms of neural plasticity. This chapter is a review of the embryology, neuroanatomy, clinical localization, evaluation, and management of adult and childhood spinal cord motor disorders.

Abstract
Objective Intramedullary spinal cord metastasis from lung cancer (ISCM-LC) are increasing in prevalence. We aim to investigate its clinical features, treatments and prognosis.
Methods We reported 6 ISCM-LC cases and conducted a systematic review. Descriptive summarization, survival analysis, and multivariate Cox regression analysis were performed to comprehensively study the disease.
Results All 6 patients had surgery. One used chemotherapy and the other had targeted drugs. Two patients died of ISCM-LC, 1 died of pulmonary embolism, 1 was alive, and 2 were lost to follow-up. We identified 197 ISCM-LC cases in literature with a mean age of 58 years and male preponderance. Small cell lung cancer accounted for 39.1%. The median interval from lung cancer to ISCM-LC was 7 months. Limb weakness was the most common symptom, and 45% cases progressed rapidly. Concomitant brain, leptomeningeal, and vertebral metastasis occurred to 55.8%, 20%, and 19.5%, respectively. Peritumoral edema appeared in 83.3%. Through survival analysis, we found sex, extraspinal metastasis, pathology, and improved symptoms affected the overall survival. Additionally, gross total resection (GTR) shared similar effectiveness with non-GTR, and other treatments following surgery hardly added extra effect. Surgery, improved symptoms, and sex were 3 independent prognostic factors after adjusting for confounding. The estimated median survival time was 5 months.
Conclusion The overall survival of ISCM-LC remains poor. Surgery is an independent protective factor for survival. Surgery should be considered once tolerated, and GTR might not be necessary. In addition, female patients with improved symptoms after intervention might have better overall survival.

Abstract
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
Roughly one third of non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI)-sensitive mutated (EGFRm) tumors experience disease progression through central nervous system (CNS) metastases during treatment. Although EGFR-TKIs have been reported to be favored in some patients with EGFRm NSCLC CNS metastases, novel EGFR-TKIs with proven efficacy in CNS pathologies are clinically needed.To investigate whether almonertinib, a novel third-generation EGFR-TKI for NSCLC, can cross the blood-brain barrier (BBB) and deliver treatment for EGFR-mutant NSCLC brain metastases and spinal cord metastases, we constructed NSCLC brain metastasis and spinal cord metastasis models in vivo to observe the anti-tumor effects of almonertinib. Using ABCB1-MDCK and BCRP-MDCK monolayer cells as the in vitro study model, the effects of transport time and drug concentration on the apparent permeability coefficient of almonertinib and its active metabolite, HAS-719, were investigated. The results of this study show that almonertinib can significantly inhibit PC9 brain and spinal cord metastases. Pharmacokinetic studies in mice revealed that almonertinib has good BBB penetration ability, whereas the metabolite HAS-719 does not easily penetrate the BBB. Early clinical evidence of almonertinib activity in patients with EGFRm-advanced NSCLC and brain metastases has also been reported. In conclusion, almonertinib easily penetrates the BBB and inhibits advanced NSCLC brain and spinal cord metastases.

Intramedullary Spinal Cord Metastasis Mimicking Astrocytoma: A Rare Case Report. Brain Sci 2021; 11:brainsci11091124. [PMID: 34573146 PMCID: PMC8464877 DOI: 10.3390/brainsci11091124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Revised: 08/14/2021] [Accepted: 08/23/2021] [Indexed: 11/25/2022] Open
Abstract
Intramedullary spinal cord metastases (ISCMs) are infrequent lesions. Their incidence is estimated to range from 0.9 to 2.1%, found in autopsies of cancer patients. However, as the life expectancy of malignant tumour patients constantly increases, the reported incidences of ISCMs are consequently rising. This report presents a case of the misdiagnosis of an anaplastic astrocytoma type of tumour due to its similarities to small-cell neuroendocrine carcinoma. Therefore, we would like to underline the importance of further investigation that could assist and support the surgeon in the making of the differential diagnosis. We present the clinical case of a 73-year-old woman with a solitary intramedullary spinal cord metastasis as the initial manifestation of a carcinoid type of tumour. The patient was admitted to our department while presenting a rapid onset of paraparesis. Magnetic resonance imaging was performed, which showed an intramedullary mass at the C2–C6 vertebral level with a heterogeneous contrast enhancement. In light of these findings, the patient underwent surgery for a partial tumour resection. The lesion resulted in being a small-cell neuroendocrine type of carcinoma. This peculiar type of tumour presents similar radiological characteristics to the anaplastic astrocytoma type, which is why our diagnostical mismatch occurred. This is the report of a rare case of solitary intramedullary spinal cord metastasis, which is the result of an initial presentation of a lung small-cell neuroendocrine type of carcinoma. We conclude that ISCMs should be regularly considered as a part of the differential diagnosis of intramedullary lesions, especially in the case of a rapid onset and deterioration of neurological symptoms.

Abstract
BACKGROUND Cerebellar medulloblastomas are the most common malignant tumors of the posterior fossa in childhood that frequently metastasize. Leptomeningeal dissemination and distant metastasis have been associated with medulloblastomas; however, intramedullary metastases are rare with very few case reports in the literature available. METHODS We present a case of a 3-year-old girl with a medulloblastoma who underwent surgical resection of spinal intramedullary metastases. Histopathology revealed the tumor to be an anaplastic medulloblastoma similar to the intracranial lesions. The patient subsequently underwent postoperative chemotherapy followed by radiotherapy. RESULTS Following the surgery and subsequent follow-up, the patient showed a good recovery without any new neurological dysfunction. CONCLUSIONS Intramedullary metastasis of medulloblastoma remains a rare disease. Surgical resection could play a possible role in the management in addition to radiation and chemotherapy.

Abstract
BACKGROUND AND IMPORTANCE Intramedullary spinal cord metastases (ISCMs) are rare and no cases of ISCM from an adenoid cystic carcinoma (ACC) of the external auditory canal (EAC) have been reported. CLINICAL PRESENTATION We report a 54-year old man complaining backpain and worsening myelopathy. He had an ACC of the EAC resected years prior. A spinal MRI demonstrated a contrast-enhancing intramedullary lesion within the conus medullaris. The histopathological diagnosis of the patient was consistent with the patient's primary cancer. At 3 months follow-up, the neurological condition of the patient was unchanged. CONCLUSIONS This is the first reported case of ISCM from a primary ACC of the EAC.

Abstract
Intramedullary spinal cord metastasis (ISCM) is a rare event in the course of advanced malignancy. Management of these lesions remains controversial. Recently, surgery for ISCM has been advocated for selected patients. We performed a retrospective analysis of the clinical course, complications, and outcome of 30 patients surgically treated for ISCM. Patients' age, histopathological diagnoses of primary cancer, tumor size, spinal location, and extramedullary tumor dissemination were collected. Preoperative functional status, pre- and postoperative neurological status, and extent of the tumor resection were also analyzed. Predominant tumor location was thoracic, followed by cervical and conus medullaris. Lung cancer constituted the majority of primary malignancies. In 9 cases, one of the indications for spinal surgery was to obtain a histopathological diagnosis. On admission, all patients presented with neurological symptoms suggestive of myelopathy. After surgery, 18 patients exhibited improvement of symptoms in terms of pain relief and partial recovery of motor and/or sensory deficits; 6 patients were unchanged, while 6 patients exhibited postoperative deterioration. Median survival time after surgery was 9.9 months. Age > 70 years old, presence of systemic metastases, preoperative neurological non functional status, and lung cancer as primary tumor were all factors associated with a worse survival prognosis. This study did not show a clear survival difference between gross total and subtotal ISCM tumor resection. Patients who underwent gross total resection had a worse functional outcome with respect to patients with only partial resection. Gross total resection with low morbidity must be the surgical target, but when not possible, subtotal resection and adjuvant therapy are a valid therapeutic option.

Abstract
Simple Summary Due to recent medical advancements, patients suffering from metastatic cancer have a prolonged life expectancy compared to several decades ago. Thus, the number of patients who experience metastasis to the spinal cord is increasing. Intramedullary metastases bear a dismal prognosis and cause considerable morbidity. Limited data are available on the treatment of such lesions. As surgery may be the mainstay of treatment for resectable and localized metastatic spread, previous case reports and series suggest radiosurgery to be a treatment alternative. This first multicenter study analyzes the efficacy of robotic radiosurgery (RRS) for the management of intramedullary metastases. Outcomes provide evidence that RRS is a safe, time-saving and effective treatment modality, especially for patients with unresectable lesions. Most patients die from systemic disease progression, while the majority of treated lesions remain controlled until death. Most symptoms improve or stay stable after treatment. These findings may guide further palliative care of affected patients. Abstract Background: Intramedullary metastases are rare and bear a dismal prognosis. Limited data are available on the treatment of such lesions. As surgery may be the mainstay of treatment for patients with resectable and localized metastatic spread, previous case reports and case series suggest radiosurgery to be another viable treatment modality. This multicenter study analyzes the efficacy and safety of robotic radiosurgery (RRS) for intramedullary metastases. Methods: Patients who received RRS for the treatment of at least one intramedullary metastasis were included. Results: Thirty-three patients with 46 intramedullary metastases were treated with a median dose of 16 Gy prescribed to a median isodose of 70%. The local control was 79% after a median follow-up of 8.5 months. The median overall survival (OS) was 11.7 months, with a 12- and 24-month OS of 47 and 31%. The 12-month progression-free survival was 42% and at 24 months 25%. In addition, 57% of patients showed either an improved or stable neurological function after treatment delivery. Systemic disease progression was the main cause of death. No significant treatment-related toxicities were observed. Conclusions: RRS appears to be a safe, time-saving and effective treatment modality for intramedullary metastases, especially for patients with unresectable lesions and high burden of disease.

Abstract
Intramedullary spinal cord metastases (ISCM) is a rare, but devastating complication of malignant disease. Prognosis is poor, with an overall median survival (OS) of 4 months from the time of diagnosis. Yet, ISCMs are being increasingly diagnosed, related to advances and increased use of imaging and therapies that prolong survival in patients with cancer. Prompt and accurate diagnosis of ISCM is necessary for effective treatment, and magnetic resonance imaging (MRI) is the preferred imaging technique. The optimal management of these patients is controversial because of the multitude of clinical circumstances and the lack of controlled studies on the efficacy of the different therapeutic approaches. Increased awareness of this rare entity may lead to an earlier diagnosis at a stage when neurological deficits are reversible, and therefore, more effective palliation may be achieved. Therefore, we carried out this retrospective research of 3 observations of ISCM, associated with a detailed review of the literature describing the diagnostic, therapeutic and evolutionary characteristics of this special rare entity.

Abstract
BACKGROUND Intramedullary spinal cord metastasis (ISCM) account for a minority of all spinal cord tumors. Rarely, symptoms from ISCM may be the initial presentation of an unknown primary carcinoma. Intramedullary metastasis from a second malignancy or from an unknown neuroendocrine malignancy is extremely rare and has never been reported in the literature. Because of the rarity of these tumors and the low volume of cases, well-defined treatment guidelines do not exist for the management of ISCM. Here we present a rare and one of the first reports of an intramedullary metastatic neuroendocrine tumor. CASE DESCRIPTION A 66-year-old woman with a history of breast cancer presented with worsening bilateral lower extremity numbness for 2 months. Imaging revealed an intramedullary spinal cord tumor at the T4 level. The patient underwent microsurgical resection of the intramedullary spinal cord tumor. At operation, the tumor had an exophytic component. Subtotal resection was achieved. Pathology revealed a neuroendocrine metastasis, likely pulmonary in origin. She achieved partial resolution of neurologic symptoms at follow-up. CONCLUSIONS Neuroendocrine ISCM are rare and lack well-defined treatment guidelines. Care should be individualized in these cases. Whenever feasible, surgical resection should be considered. Despite multidisciplinary care, the prognosis is dismal with limited life expectancy. Larger, multiinstitutional, or national database studies are needed that compare treatment modalities in the management of ISCM to identify the therapy with the best outcomes.

Abstract
Spinal cord lesions are traditionally classified as either extradural or intradural extramedullary or of intramedullary origin. Intramedullary spinal cord tumours are histopathologically similar to cranial tumours with a diverse range of pathologies. Astrocytomas and ependymomas account for approximately 80% of all intramedullary tumours, with other primary and secondary lesions accounting for the remaining 20%. Magnetic resonance imaging is the preferred imaging modality for diagnosing and characterising spinal cord lesions; however, accurate characterisation of tumour histology can be challenging, and is further confounded by intramedullary non-neoplastic lesions, such as demyelinating vascular, inflammatory, infectious, or traumatic lesions. This review illustrates the spectrum of intramedullary tumours and tumour mimics with emphasis on the imaging findings.

Abstract
Spinal cord tumors are a challenge for patients and neurosurgeons because of the high risk of neurologic deficits from the disease process and surgical interventions. Spinal cord tumors are uncommon, and approximately 2%-3% of primary intra-axial tumors of the central nervous system occur in the spinal cord. Primary intra-axial tumors are usually derived from neuroepithelial tissue, especially glial cells. This often leads to a classic intramedullary mass differential diagnosis of ependymoma or astrocytoma, which together constitute up to 70% of spinal cord tumors. For example, ependymomas occur predominantly in adults, and astrocytomas (specifically pilocytic astrocytomas) occur predominantly in children. While that is an excellent starting point, in order to refine the differential diagnosis, the authors review the radiologic-pathologic features of specific neoplastic categories and entities recognized by the World Health Organization (WHO) in the 2016 WHO Classification of Tumours of the Central Nervous System and a few additional congenital-developmental entities. Radiologists can add value by providing a reasonable preoperative differential diagnosis for the patient and neurosurgeon, in many cases by favoring the most common conditions, and in other cases by identifying radiologic features that may point toward a less common entity. Some of the less common entities include intramedullary myxopapillary ependymoma, spinal subependymoma, and spinal hemangioblastoma. Whenever possible, the characteristic imaging features and locations of these tumors are explained or traced back to the underlying cell of origin and findings seen at histopathologic examination.See discussion on this article by Buch.

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 Intramedullary metastases to the caudal neuraxis with exophytic extension to the extramedullary space are rare. We describe the unique case of a patient with locally recurrent breast cancer who developed an intramedullary-extramedullary metastasis to the conus medullaris and cauda equina 22 years after primary diagnosis, the longest interval between primary breast cancer and intramedullary spread to date. We also reviewed the published literature on focal breast metastases to the conus medullaris or cauda equina. CASE DESCRIPTION A 66-year-old woman with a history of node-positive estrogen receptor/progesterone receptor-positive, infiltrating ductal carcinoma diagnosed in 1997 and locally recurrent in 2007. Initial treatment included lumpectomy and targeted chemoradiation with mastectomy and hormonal therapy at recurrence. Twelve years later, she developed 6 weeks of bilateral buttock and leg pain without motor or sphincter compromise. Magnetic resonance imaging of the total spine revealed a 2 x 1.7 cm bilobed intradural, intramedullary-extramedullary, homogenously enhancing, T1-and T2-isointense lesion involving the conus medullaris and cauda equina. She underwent subtotal resection of a hormone receptor-positive breast metastasis. Her pain improved postoperatively and she was stable at 5 months. CONCLUSIONS We provide evidence that patients who present with symptoms of spinal neurologic disease and a history of hormone receptor-positive breast cancer require high suspicion for metastatic pathology, despite significant time lapse from primary diagnosis. The tumor may involve both the intramedullary and extramedullary space, complicating resection. Symptom relief and quality of life should guide resection of metastatic lesions to the caudal neuraxis.

Abstract
PURPOSE Peripheral enhancement characteristics on magnetic resonance imaging (MRI), namely the rim and flame signs, are specific for intramedullary spinal cord metastases (ISCM) compared to primary cord masses. The study compared the frequency of a novel finding-the central dot sign-in ISCMs versus primary intramedullary masses. METHODS In this study 45 patients with 64 ISCMs and 64 control patients with 64 primary intramedullary cord masses were investigated and 2 radiologists blinded to lesion type independently evaluated MR images for the presence of a central dot sign: a punctate focus of enhancement in/near the center of an enhancing intramedullary mass. The frequency of this sign in the two patient groups was compared. RESULTS A total of 63 enhancing ISCMs in 44 patients and 54 enhancing primary cord masses in 54 patients were included. The central dot sign was identified in 6% (4/63) of enhancing ISCMs in 9% (4/44) of patients and in none (0/54) of the enhancing primary cord masses (p = 0.038, per patient). The specificity for diagnosing ISCMs among spinal cord masses was 100%. The central dot sign was present in the axial plane only in two ISCMs and in the axial and sagittal planes in two ISCMs. The two ISCMs harboring the central dot sign also demonstrated both the previously described rim and flame signs, and two also demonstrated the rim sign alone. CONCLUSION The central dot sign is not sensitive but highly specific for ISCMs compared to primary spinal cord masses. The rim and/or flame signs may or may not be concurrently present in ISCMs.

Abstract
A woman in her late sixties was referred to the orthopaedic clinic with progressive lower limb weakness and gait disturbance. She was known to have breast cancer with pre-existing infiltrative disease in the left brachial plexus. Magnetic resonance imaging of the spine revealed an intramedullary spinal cord metastasis in the lower cervical cord at C6-C7. She underwent surgical excision but died within six weeks of surgery. This rare case of an intramedullary spinal cord metastasis highlights the extremely poor prognosis in this condition as well as the possibility of perineural invasion into the spinal cord from the brachial plexus lesion. A detailed discussion of the literature on intramedullary spinal cord metastases is also presented.

Abstract
Rates of malignant melanoma have been increasing in frequency. Studies have shown that up to 46% of patients with melanoma will experience metastases to the central nervous system. Intramedullary spinal cord metastasis of malignant melanoma is rare. In advanced cancers, surgery might not be possible, and radiotherapy with corticotherapy is a viable option. In the following case, a 54-year-old male presented to the clinic with an intramedullary tumor in the D1 region. He was successfully managed with an integrated palliative care approach with concomitant cancer-directed therapy.

Abstract
PURPOSE OF REVIEW This article discusses the diagnosis and management of neoplasms that affect the spinal cord as well as spinal cord disorders that can occur due to cancer treatments. RECENT FINDINGS Neoplastic myelopathies are uncommon neurologic disorders but cause significant morbidity when they occur. Primary spinal cord tumors can be classified into intramedullary, intradural extramedullary, or extradural tumors. Diffuse gliomas and ependymal tumors are the most common intramedullary tumors. Diffuse gliomas include the World Health Organization (WHO) grade II and grade III astrocytomas, the grade II and grade III oligodendrogliomas, the grade IV glioblastomas, and newly recognized pediatric diffuse midline gliomas with H3 K27M mutation. The majority of diffuse and anaplastic astrocytomas are IDH-mutant tumors, whereas only 10% of glioblastomas are IDH-mutant. Oligodendrogliomas are typically IDH-mutant and are characterized by the molecular signature of 1p/19q codeletion. Nine distinct molecular subgroups of ependymomas have been identified based on their genetic features and location. NF2 mutations are frequently found in spinal cord ependymomas. Metastatic tumors are the most common tumors of the spine and can be extradural, leptomeningeal, or, rarely, intramedullary. Extradural metastatic spinal cord compression is a neurologic emergency and should be promptly diagnosed as pretreatment neurologic status dictates the posttreatment outcome. SUMMARY Neoplastic myelopathies encompass many diagnoses ranging from benign and malignant spinal tumors to paraneoplastic syndromes heralding cancers. The knowledge of the clinical features and management of neoplastic myelopathies is essential to practicing neurologists as early diagnosis and treatment can prevent devastating neurologic sequelae.

Abstract
Intramedullary spinal cord metastases (ISCMs) of non-small cell lung cancer (NSCLC) constitute a serious if infrequent complication, characterised by rapid progression of neurological deficits, with poor prognosis. We describe a 52-year-old man with ISCMs secondary to lung adenocarcinoma who acquired the T790M mutation of the epidermal growth factor receptor (EGFR) after previous use of a first-generation EGFR tyrosine kinase inhibitor (TKI); he was successfully treated with osimertinib. This is the first report of the use of osimertinib in ISCMs: due to its high central nervous system activity, osimertinib could be useful for treating ISCMs secondary to NSCLC in patients who exhibit the T790M mutation.

Abstract
Background: Intramedullary spinal cord metastases (ISCM) in malignancies is a devastating issue with limited research. This study aims to identify the clinical features, management, prognostic factors, and outcomes of this special entity. Methods: A retrospective review of 61 patients of ISCM diagnosed and treated in our institute from June 2010 to March 2018 was conducted (lost to follow-up: 3). Data were retrieved according to the items including age, gender, primary tumor, interval to the ISCM occurrence, ISCM segments, and other synchronous metastases. The interventions, response, prognostic factors, and outcomes of ISCM were systematically analyzed. Results: Lung cancer (67.21%) was the commonest ISCM source, followed by breast cancer (14.75%). In total, 9.84% of patients presented with ISCM initially. The mean span from the primaries to ISCM was 18.77 months (range=0–10 years). The thoracic segment was most commonly involved (77.05%), followed by cervical (39.34%), lumbar level (34.43%), and conus medullaris (6.56%). The management of ISCM was challenging, since 55.74% of individuals had a poor physical condition (PS=3–4) and 72.41% had widespread dissemination synchronously (≥2 organs). Radiotherapy (RT) attained an objective response rate (ORR) of 61.90% or 62.50% and a local control rate (LCR) of 90.48% or 87.50% for symptoms used alone or with other strategies, respectively. ISCM bears a dismal prognosis, with a median overall survival (OS) of 4 months. Patients with only one segment involved had an apparently better prognosis than those with 2–4 involved segments (median OS=7.0 vs 3.0 months) (P<0.01). The OS of patients treated was remarkably superior to those without any intervention (median OS=5.0 vs 2.0 months) (P<0.01). Conclusion: ISCM is a distinct entity needing more attention for high cancer incidence, prolonged survival, and lack of research. RT is the mainstay with satisfactory effect. Multiple spinal cord segments involvement and no treatment are poor prognostic factors of OS.

Abstract
The rearrangements of anaplastic lymphoma kinase (ALK) and the c-ros oncogene 1 (ROS1) have both been important driving factors in non-small-cell lung cancer (NSCLC). They have already been defined in 3-5% of NSCLC patients. ALK and ROS1 rearrangements are associated with unique clinical and pathological features, especially patients are usually younger, with milder or never smoking history, and adenocarcinoma histology. Also, they have both been found to contribute to the metastasis of NSCLC by cell migration and invasion. It has recently been recognized that the brain can be considered as a primary site for metastasis in cancers with ALK or ROS1 rearrangements. The present review summarizes the current status of NSCLC metastasis and possible mechanisms based on available evidence, and then we list possible therapeutic strategies so that an increase in control of ALK and ROS1 rearrangement of NSCLC metastases by combination therapy can be translated in an increase in overall survival and prognosis.

Abstract
BACKGROUND Medulloblastomas are common childhood central nervous system tumors that are prone to leptomeningeal spread. Intramedullary dissemination is rare with very few case reports existing in the available literature. CASE DESCRIPTION The authors here present a case of a 14-year-old boy with Li-Fraumeni syndrome and medulloblastoma who underwent surgical resection of spinal intramedullary spread. Histopathology revealed the tumor to be anaplastic medulloblastoma, same as the intracranial lesions. Genetic testing of the metastatic deposit revealed loss of functions mutations in SUFU, NOTCH3, and TP53 and TERC amplification. An improvement in ambulatory function at short-term follow-up was noted before the patient died of disseminated disease. CONCLUSIONS Intramedullary metastasis of medulloblastoma remains a rare disease. Surgical resection might play a possible role in management in addition to radiation and chemotherapy.

Abstract
Neurologic complications of cancer may involve both the central nervous system and peripheral nervous system manifesting as brain, leptomeningeal, intramedullary, intradural, epidural, plexus, and skull base metastases. Excluding brain involvement, neurologic complications affecting these other sites are relatively infrequent, but collectively they affect more than 25% of patients with metastatic cancer causing significant morbidity and mortality. Early diagnosis and intervention optimize quality of life and improve survival.

Abstract
The spine is the third most common site for distant metastasis in cancer patients with approximately 70% of patients with metastatic cancer having spinal involvement. Positron emission tomography (PET), combined with computed tomography (CT) or magnetic resonance imaging (MRI), has been deeply integrated in modern clinical oncology as a pivotal component of the diagnostic work-up of patients with cancer. PET is able to diagnose several neoplastic processes before any detectable morphological changes can be identified by anatomic imaging modalities alone. In this review, we discuss the role of PET/CT and PET/MRI in the diagnostic management of non-osseous metastatic disease of the spinal canal. While sometimes subtle, recognizing such disease on FDG PET/CT and PET/MRI imaging done routinely in cancer patients can guide treatment strategies to potentially prevent irreversible neurological damage.

Abstract
AbstractLongitudinally extensive transverse myelitis (LETM) is an unusual manifestation of systemic malignancy. It has been mainly reported with lung cancers and lymphoproliferative malignancy. LETM in systemic malignancy can be caused by either intramedullary metastases or paraneoplastic syndrome. Occurrence of LETM as the first manifestation of malignancy has been rarely reported. We present clinical, laboratory, and imaging findings of a 66-year-old man with nonsmall-cell lung (adeno) carcinoma, who presented with LETM without having any cardinal manifestations of lung malignancy. The rarity of the disease and especially such a presentation can cause considerable delay in the diagnosis and treatment.

Abstract
Intramedullary spinal cord metastasis (ISCM) is rare and occurs most commonly in the setting of advanced malignancy. The optimal management pathways are not well defined and treatment outcomes from contemporary therapies remain variable. We report a case of a 49-year-old woman with known primary papillary thyroid carcinoma, who presented with rapidly progressive clinical features of Brown-Sequard syndrome. A detailed pooled analysis of the literature was conducted to characterise the clinical and demographic features, management options, and expected survival outcomes for cases of ISCM. We secondarily performed a subgroup analysis on the incidence, clinical and management characteristics of thyroid carcinoma ISCM.

Abstract
OBJECTIVE Metastasis to the spinal cord is rare, and optimal management of this disease is unclear. The authors investigated this issue by analyzing the results of surgical treatment of spinal intramedullary metastasis (IM) at a major cancer center. METHODS The authors retrospectively reviewed the medical records of 13 patients who underwent surgery for IM. Patients had renal cell carcinoma (n = 4), breast carcinoma (n = 3), melanoma (n = 2), non-small cell lung cancer (n = 1), sarcoma (n = 1), adenoid cystic carcinoma (n = 1), and cervical cancer (n = 1). Cerebrospinal fluid was collected before surgery in 11 patients, and was negative for malignant cells, as was MRI of the neuraxis. Eleven patients presented with neurological function equivalent to Frankel Grade D. RESULTS Radiographic gross-total resection was achieved in 9 patients, and tumor eventually recurred locally in 3 of those 9 (33%). Leptomeningeal disease was diagnosed in 4 patients after surgery. In the immediate postoperative period, neurological function in 6 patients deteriorated to Frankel Grade C. At 2 months, only 2 patients remained at Grade C, 8 were at Grade D, and 1 had improved to Grade E. One patient developed postoperative hematoma resulting in Frankel Grade A. Radiotherapy was delivered in 8 patients postoperatively. The median survival after spine surgery was 6.5 months. Three patients are still living. CONCLUSIONS Surgery was performed as a last option to preserve neurological function in patients with IM. In most patients, neurological function returned during the immediate postoperative period and was preserved for the patients' remaining lifetime. The data suggest that surgery can be effective in preventing further decline in selected patients with progressive neurological deficit.

Abstract
BACKGROUND Most metastatic spinal cord lesions are located either in the intradural, extramedullary, or in the epidural compartments. Intramedullary spinal cord metastasis (ISCM) is a rare central nervous system spread of cancer. The aim of this report was to evaluate ISCM in the published literature. METHODS A literature review of PubMed from 1960 to 2016 was undertaken for the publications having demographic, clinical, histological, and outcome data. RESULTS A total of 59 relevant papers were identified, showing 128 cases of intramedullary metastasis from lung cancer. The incidence of lung cancer as the primary malignancy with intramedullary metastasis was 56%. The median time from diagnosis of primary to intramedullary metastasis was 6months. Survival improved with multimodality therapy compared to monotherapy (4monthsvs. 6.3months) (hazard ratio=0.501; 95% confidence interval, 0.293-0.857). CONCLUSION Lung cancer is the predominant cause of intramedullary involvement of the spinal cord. Overall prognosis is poor, although a multimodality approach was associated with improved survival.

Abstract
Laryngeal cancer metastases are relatively rare and mainly affect the lung. The medullary localization remains exceptional. We report the case of a patient followed for operated laryngeal cancer and whose oncologic control revealed a medullary localization. A patient followed for squamous cell carcinoma of the larynx, treated in 2010 by a partial surgery whose endoscopic control at 5 years revealed the presence of right arytenoid edema without suspicious lesions, multiple biopsies were made and which returned negative. A month later, the patient presented a rebel cervical spine pain and a feeling of heaviness of the upper limbs, for which a radiological assessment was done finally objectifying a right hypopharyngeal process and a suspicious right internal jugular lymphadenopathy (biopsy confirmed the squamous type), as well as an intramedullary metastasis. This case is an illustration of an exceptional evolution of this type of cancer and a are metastatic localization difficult to highlight, which leads us to ask the question on the need of simultaneous and systematic radiological and endoscopic control treatment for operated laryngeal cancer.

Abstract
Leiomyosarcoma (LMS) is a rare but well-recognized malignant soft tissue sarcoma of smooth muscle origin. Metastases commonly occur in the lungs, liver, kidney, brain, and bone. Cases of metastatic osseous lesions or other extradural space-occupying masses secondary to LMS leading to neurologic compromise are relatively commonplace in the literature. Conversely, cases of intramedullary spinal cord metastasis (ISCM), an unusual entity as a sequela of any cancer, are exceedingly rare as a consequence of LMS. Only 2 cases of an ISCM from LMS are currently documented in the literature, and to the best of our knowledge, no case is described in the rehabilitation literature. This case report presents a patient with a history of longstanding metastatic LMS presenting with incomplete paraplegia, neurogenic bowel and bladder, and neuropathic pain. The patient was found to have an ISCM of the thoracic spinal cord. She made functional gains with concurrent inpatient rehabilitation and radiation but was unable to perform her own intermittent catheterization program, bowel program, or transfers and was unable to discharge home independently. Intramedullary spinal cord metastasis is a rare and potentially devastating consequence of LMS or any primary cancer, but can be amenable to common interventions in the acute inpatient rehabilitation setting.

Abstract
Spinal glioblastoma multiforme (GBM) is uncommon, and its diagnosis may be challenging. This is especially true in the elderly population. Best management strategy remains to be defined. The purpose of this report is to document this rare condition, increase awareness (as a potential differential diagnosis) and propose treatment options in the elderly; a review of the relevant literature is included. A biopsy may be beneficial in given circumstances as cervical spinal GBM carries a better prognosis compared with intramedullary metastasis.

Regional Spinal Cord Atrophy Is Associated with Poor Outcome After Surgery on Intramedullary Spinal Cord Ependymoma: A New Aspect of Delayed Neurological Deterioration.

Abstract
BACKGROUND A considerable number of patients suffer delayed neurologic deficits, even after a successful removal of intramedullary spinal cord ependymoma. The underlying pathology remains unknown. Radiologic findings could provide an explanation for poor outcome after surgery. METHODS We conducted a retrospective study of all cases treated from 1980 to 2016 in our department. The cohort included all patients with intramedullary spinal cord ependymoma treated with microsurgical excision. The cross-sectional area of the spinal cord at the level of the former performed surgery was compared using magnetic resonance imaging (MRI), follow-up MRI, adjacent unaffected levels, and the control group. RESULTS Fifty-four patients with an intramedullary spinal cord lesion were treated in this period. Ependymoma was the predominant tumor (n = 28) followed by intramedullary gliomas and vascular lesions. Mean age (±SD) was 48.2 ± 10.5 years with a female predominance (16 women, 12 men). An unfavorable outcome was observed in 53% of the patients after an initially uneventful postoperative course. The follow-up cross-sectional area of the spinal cord was significantly reduced in these patients compared to adjacent unoperated levels and the control group. Sagittal and axial spinal MRI showed spinal cord narrowing owing to atrophic changes in the area of the performed surgery in 53% of patients with resected ependymoma after a mean follow-up time of 9 years. Functional outcome in ependymoma was significantly associated with spinal cord atrophy (P < 0.05). CONCLUSIONS Spinal cord atrophy seems to be a predicting factor in long-term outcome after surgical removal of intramedullary spinal cord ependymoma.

Abstract
We report and analyze a rare entity of intramedullary spinal cord tumor, which is metastatic from colon cancer with a very poor prognosis. The reported 19 cases including our case in the literature are analyzed. Comparison of outcomes between surgery, radiotherapy and non-treatment groups are evaluated. Life distribution is profiled. Median overall survival is 75 days. The 90 days and 150 days survival rate are 42.9% and 21.4%, respectively. There were no differences between conservative treatment (non-treatment or radiotherapy) and aggressive intervention (surgery or surgery plus radiotherapy) in mortality and the trend of survival probability. The prognosis of metastatic intramedullary spinal cord tumor is poor. Surgery may only be considered in selected patients with good control of primary cancer and without evidence of lung metastases and leptomeningeal carcinomatosis.
