Abstract
Secondary leptomeningeal gliomatosis is a condition known as a result of invasion of the subarachnoid space or the ventricular system of primary intraparenchymal glioma. In this article, we present a 7-year-old boy presented with neck and back deformity and deterioration of gait. Cranial and spinal magnetic resonance imaging revealed lesions in the supratentorial and infratentorial areas, in the brainstem downward the spinal cord. Disseminated oligodendrogliomatosis is extremely rare and our case we present is the 24th in the literature.

Abstract
Anaplastic Oligodendroglioma has a better prognosis in the presence of 1p19q co-deletion and IDH-1 mutation but spinal leptomeningeal dissemination of cerebral anaplastic oligodendroglioma is a rare occurrence. We describe the case of a 47 year old man with spinal leptomeningeal dissemination eight months after resection of an anaplastic cerebral oligodendroglioma presenting with encephalitic features. We present the radiological, biochemical, intraoperative and histological features of this syndrome. Despite resolution of symptoms with corticosteroid treatment and favourable biochemical markers, prognosis remains poor when spinal leptomeningeal disease is present.

Abstract
This article describes an unusual presentation of disseminated oligodendroglial-like leptomeningeal tumour. A previously healthy 23-year-old Caucasian woman presented with headache, photophobia and recurrent seizures. Initial investigations were suggestive of subarachnoid haemorrhage. Her symptoms deteriorated rapidly and within weeks she developed complete blindness and diffuse sensory ataxia. The aim of this article is to increase awareness of this rare disease, especially in patients who present with acute, rapidly progressive neurological symptoms with signs of acute or chronic central nervous system bleeding.

Abstract
INTRODUCTION Diffuse leptomeningeal glioneuronal tumor is a new entity under the neuronal and mixed neuronal-glial tumors in the WHO 2016 updated classification and commonly found in children and adolescents. The initial diagnosis is challenging because of its non-specific radiologic feature and negative CSF cytology analysis. A 17 years male was presented with intractable headache subsequently followed by back pain and joint pain. MRI showed enhancement of arachnoid membrane at basal cistern, bilateral sylvian fissure and cerebral cistern with slight enlargement of ventricles. There were no evidences of infection in CSF and blood samples. Based on the duodenal biopsy and prodromal symptom of joint pain, the patient was suspected of having Whipple's disease. Eleven months after the onset, a small mass lesion was observed at the anterior horn of right lateral ventricle. The histology was remarkable for anaplastic oligodendroglioma. Immunostainings revealed positivity for GFAP, Olig2, synaptophysin and negativity for IDH1 mutation, H3K27M. MIB1 labeling index was 40% and 1p19q FISH analysis showed only 1p deletion. Therefore, a final diagnosis of DLGNT was made. CONCLUSION DLGNT should be included as a differential diagnosis of patients with leptomeningeal-enhanced and high CSF protein level with normal white blood cell count.

Abstract
LITERATURE REVIEW In this study, we evaluated a case of primary spinal oligodendroglioma (PSO) with a rare localization between L3 and S2, and also examined sixty cases in the literature in terms of demographic characteristics, clinical, radiological, and histopathological characteristics, and treatment planning. A case of PSO has been presented, and the relevant literature between 1931 and 2016 was reviewed. A total of 57 papers regarding PSO were found and utilized in this review. The main treatment options include radical surgical excision with neuromonitoring, followed by radiotherapy. Despite these treatment protocols, the relapse rate is high, and treatment does not significantly prolong survival. Oligodendrogliomas are rare among the primary spinal cord tumors. Oligodendrogliomas are predominantly found in the cervical spinal cord, thoracic spinal cord, or junctions during childhood and adulthood. Extension to the sacral region, inferior to the Conus, is very rare. Furthermore, of the sixty cases in the literature, the case we present here is the first to be reported in this particular age group. These localizations usually occur in the pediatric age group and after relapses. While for a limited number of cases the oligodendroglioma initiates in the thoracic region and reaches as far as L2, we encountered a case of an oligodendroglioma within the range of L3 to S2. Clinical findings are observed in accordance with location, and magnetic resonance imaging is the gold standard for diagnosis.

Abstract
BACKGROUND AND IMPORTANCE Spinal cord oligodendrogliomas are rare tumors, with a reported incidence varying between 0.8% and 4.7% of all spinal cord tumors and just over 50 cases reported in the literature. Of these, only 9 cases are histologically defined as anaplastic oligodendrogliomas, with few having complete molecular characterization. The diffuse tumor spread that can occur along the subarachnoid space with secondary invasion of the leptomeninges is called oligodendrogliomatosis and is associated with poor outcome. CLINICAL PRESENTATION A 68-year-old man with a history of lumbar stenosis status after lumbar decompression presented with new-onset right lower-extremity weakness. Magnetic resonance imaging demonstrated an intramedullary lesion from T9 to T12. During an attempted diagnostic biopsy, numerous intradural intramedullary lesions not present on magnetic resonance imaging were observed. Tissue biopsy demonstrated a 1p/19q-codeleted anaplastic oligodendroglioma with diffuse oligodendrogliomatosis. Postoperative treatment included 39.2-Gy radiation over 22 fractions from T1 to the bottom of the thecal sac with a boost to the T9-T12 area, the primary site of disease, to a total dose of 43.2 Gy in 24 fractions, followed by adjuvant temozolomide at a dose of 200 mg/m on days 1 to 5 in a 28-day cycle. At the 1-year follow-up, the patient demonstrated moderate neurological improvement. CONCLUSION Management, prognosis, and use of molecular data in the decision-making algorithm for these patients are discussed, together with a review of all cases of primary intradural intramedullary spinal anaplastic oligodendrogliomas reported to date. Our study indicates that the combination of sequential treatment with radiation and temozolomide might provide a favorable outcome in the case of 1p/19q-codeleted spinal anaplastic oligodendrogliomas and that molecular analysis can be beneficial in guiding treatment strategies, although the impact of IDH mutations on these tumors is still unclear.

Abstract
Astrocytomas are the most common intramedullary spinal cord tumors in pediatric and adolescent patients and the incidence decreases with age. Spinal oligoastrocytoma, which is a mixed glioma with distinct astrocytic and oligodendroglial components, is an extremely rare pathology of the spinal cord. To authors' best of knowledge, there are only 7 spinal oligoastrocytomas reported in the English literature. Here, the authors report a patient of a pathologically confirmed spinal oligoastrocytoma, who presented with severe left leg pain and numbness. This patient reminds us of the rarity of spinal oligoastrocytoma, and the treatment and prognosis were also investigated and reviewed.

Abstract
Primary spinal cord oligodendrogliomas are rare tumors comprising two percent of all spinal cord tumors. Although a treatment guideline has yet to be established, maximal surgical resection is primary in the treatment of spinal cord oligodendrogliomas. Adjuvant radiotherapy has remained controversial, and it is unclear whether chemotherapy adds any benefit. In this case report, the authors present a 24-year-old male who had a seven-year history of left leg weakness and a radiating pain in both legs. Magnetic resonance image (MRI) showed an intramedullary mass at the T4-T8 level. He underwent subtotal removal of the tumor and pathologic diagnosis revealed a WHO grade II oligodendroglioma. The patient was treated with radiotherapy postoperatively and followed up with MRI annually. Clinical and radiological status of the patient had been stationary for four years after the surgery. The five-year follow-up MRI showed an increase in the size and extent of the residual tumor. Despite radiological progression, considering that symptoms and the performance status of the patient had remained unchanged, further treatment has not been performed. Given the clinical outcome of this patient, close observation after subtotal removal with adjuvant radiotherapy is one of the acceptable treatment options for WHO grade II spinal cord oligodendrogliomas.

Abstract
INTRODUCTION Oligodendrogliomatosis is a rarely reported entity in literature associated with poor prognosis in terms of length and quality of life. In this paper, we describe oligodendrogliomatosis in a 15-year-old male who initially presented with altered mental status due to diabetic ketoacidosis. CLINICAL PRESENTATION He was refractory to temozolomide initially but demonstrated disease regression with radiotherapy (XRT). More recently, he has had disease recurrence, which was stabilized with temozolomide therapy for a period of time. CONCLUSION Contrary to most reports in literature, our patient has had excellent quality of life since his initial diagnosis and continues to carry good prognosis. In addition to oligodendrogliomatosis, our patient also developed multiple intracranial cavernomas secondary to radiation therapy, which have remained stable and asymptomatic.

Abstract
Rare, generally pediatric oligodendroglioma-like neoplasms with extensive leptomeningeal dissemination have been interpreted variably as glial, oligodendroglial or glioneuronal. The clinicopathologic features have not been fully characterized. We studied 36 patients, 12 females and 24 males with a median age of 5 years (range 5 months-46 years). MRI demonstrated leptomeningeal enhancement, frequently with cystic or nodular T2 hyperintense lesions within the spinal cord/brain along the subpial surface. A discrete intraparenchymal lesion, usually in the spinal cord, was found in 25 (of 31) (81 %). Tumors contained oligodendroglioma-like cells with low-mitotic activity (median 0 per 10 high power fields, range 0-4), and rare ganglion/ganglioid cells in 6 cases (17 %). Tumors were mostly low-grade, with anaplastic progression in 8 (22 %). Immunohistochemistry demonstrated strong reactivity for OLIG2 (7 of 9) (78 %), and moderate/strong S100 (11 of 12) (92 %), GFAP (12 of 31) (39 %) and synaptophysin (19 of 27) (70 %). NeuN, EMA, and mutant IDH1 (R132H) protein were negative. Median MIB1 labeling index was 1.5 % (range <1-30 %). FISH (n = 13) or SNP array (n = 2) demonstrated 1p loss/intact 19q in 8 (53 %), 1p19q co-deletion in 3 (20 %), and no 1p or 19q loss in 4 (27 %). Clinical follow-up (n = 24) generally showed periods of stability or slow progression, but a subset of tumors progressed to anaplasia and behaved more aggressively. Nine patients (38 %) died 3 months-21 years after diagnosis (median total follow-up 5 years). We report a series of a neoplasm with distinct clinicopathologic and molecular features. Although most progress slowly, a significant fraction develop aggressive features.

Abstract
In this paper the authors describe the rare disorder of diffuse leptomeningeal oligodendrogliomatosis in a patient with an oligodendroglioma of the cauda equina who died suddenly. Reviewing this uncommon pathological entity is important so that it can be recognized and treated appropriately. This young, otherwise healthy woman with initial symptoms of low-back pain had a mass lesion of the cauda equina. During a workup, profound refractory intracranial hypertension suddenly developed despite aggressive surgical and medical intervention. Autopsy revealed a spinal cord oligodendroglioma with diffuse leptomeningeal oligodendrogliomatosis of the brain and spinal cord. Given the unforeseen outcome in this patient, this entity, although rare, should be considered in patients with similar presentations and addressed early to prevent similar outcomes. A review of the details of this case as well as the literature is presented below.

Abstract
Primary spinal cord oligodendroglial tumor is very rare, and in only one patient with spinal cord oligodendroglioma has a deletion of chromosome 1p/19q been reported. We present the case of an 18-year-old girl, who had one-year lower back pain and one-month lower limb weakness. Magnetic resonance images of the spinal cord showed an intramedullary mass from level T8 to T10, which was then radically removed. Histology revealed an anaplastic oligodendroglioma. The patient was treated with radiotherapy postoperatively. Eight months after the treatment, follow-up magnetic resonance images disclosed an enhancing intramedullary mass at level T4-T8; recurrence of the tumor was therefore diagnosed. Maximum surgical removal of the recurrent tumor was performed, diagnosis of anaplastic oligodendroglioma was made, and a chromosome 1p deletion was determined by FISH. After treatment with temozolomide for six months, the patient had a remarkable improvement of her lower limb symptoms, and complete imaging regression of the residual tumor showed no evidence of recurrence at any other sites. The most recent MRI of brain and spinal cord showed postoperative changes without evidence of tumor recurrence of the spine and oligodendrogliomatosis along the cerebral-spinal axis. To our knowledge, this is the first report of a recurrent anaplastic oligodendroglioma with 1p deletion occurring in the spinal cord. It is also the first case of the patient with recurrent intramedullary anaplastic oligodendroglioma who had a significant clinical improvement and complete imaging remission after subtotal resection then treatment with temozolomide chemotherapy.
