Franziska J Vettermann, Julia E Neumann, Bogdana Suchorska, Peter Bartenstein, Armin Giese, Mario M Dorostkar, Nathalie L Albert, Ulrich Schüller
K27M midline gliomas are diffuse gliomas that usually occur in children and young adults and arise in midline structures of the brain, the brain stem and the spinal cord. They are defined by point mutations within the chromatin modifiers H3 and are usually associated with a bad clinical outcome [1,2,3]. As such, they are represented as a new separate entity in the new version of the WHO classification for tumors of the central nervous system. Interestingly, these tumors display a huge histological variability [4] and diagnoses currently range from low grade astrocytoma (WHO-grade II) to glioblastoma (WHO-grade IV)...

BACKGROUND AND PURPOSE: Primary MRI diagnosis of spinal intramedullary tumor-suspected lesions can be challenging and often requires spinal biopsy or resection with a substantial risk of neurological deficits. We evaluated whether Diffusion Tensor Imaging (DTI) tractography can facilitate the differential diagnosis. MATERIALS AND METHODS: Twenty-five consecutive patients with an intramedullary tumor-suspected lesion considered for spinal surgery were studied with a Diffusion-weighted multi-shot read out segmented EPI sequence (RESOLVE)...

OBJECTIVE Surgical excision is the mainstay treatment for resectable low-grade intramedullary spinal cord tumors (IMSCTs) in the pediatric age group. Chemotherapy and radiation treatments are generally reserved for progressive or recurrent disease. Given the indolent nature of low-grade tumors and the potential side effects of these approaches, their long-term treatment benefits are unclear. The aim of the study was to determine long-term disease outcomes and the therapeutic roles of surgery and adjuvant therapies in pediatric patients with low-grade IMSCTs over an extended follow-up period...

Ependymomas are common spinal lesions, with the vast majority arising in an intramedullary location. Several cases have been described in the literature of ependymomas in an intradural, extramedullary location. The authors present a case of a 56-year-old female who presented with several weeks of lower back pain and weakness. MRI revealed an intradural, extramedullary enhancing mass at L1-L2. The mass was successfully resected surgically. Pathologic evaluation revealed a low grade glioma with components of both ependymoma and pilocytic astrocytoma with MUTYH G382D mutation...

INTRODUCTION: Glioma classification and grading has been historically based in morphologic appearance of tumor cells: astrocytomas, oligodendrogliomas, oligoastrocytomas and ependymomas. Recent molecular advances have transformed the field of neuro-oncology, as some molecular markers harbor diagnostic, prognostic and therapeutic implications. AREAS COVERED: In this paper we will review the major molecular changes associated with gliomas and their implications in diagnosis, prognosis, and opportunities in therapeutics...

Pilocytic astrocytomas correspond to low-grade gliomas and therefore metastasize exceedingly rare. However, pilocytic astrocytomas are able to and leptomeningeal dissemination may be seen. What are the treatment options of these cases? We present a case report of a 3-year-old child with a pilocytic astrocytoma of the optic chiasm with leptomeningeal dissemination of the spinal meninges. Partial resection of the cerebral tumor has been performed. Since the leptomeningeal dissemination was seen all over the spinal meninges, the child did not undergo further surgical treatment...

Cranial nerve thickening as an initial isolated presentation of CNS lymphoma is rare. Once an extremely rare neoplasm, primary lymphoma of the central nervous system (CNS) now ranks only next to meningiomas and low-grade astrocytomas in prevalence. Multiple cranial nerve thickening can be a feature of primary CNS lymphoma. Here we report a case of a 45-year-old immunocompetent female who presented with relapsing remitting multiple cranial nerve thickening as an initial feature of primary CNS lymphoma without any other brain or spinal cord lesions...

PURPOSE: To determine the biologic behavior and prognostic factors of spinal cord astrocytoma, we reviewed surgical and clinical outcomes. Due to the rarity of spinal cord astrocytoma, there is a lack of research regarding this type of tumor and malignant transformation. METHODS: We retrospectively reviewed the data from all patients on whom we performed spinal cord tumor removal between 1983 and 2014. Twenty-six patients were pathologically confirmed to have spinal cord astrocytoma or glioblastoma...

Spinal cord gliomas, consisting mostly of ependymomas and astrocytomas, are rare entities. Of the gliomas, infiltrating astrocytomas are particularly challenging entities to treat due to their invasive nature. Surgical resection is oftentimes not possible without subjecting patients to permanent neurological deficits because of the difficulty in establishing clear tissue planes. As more is learned about the molecular genetics, genomics, and biology of these tumors, it is becoming more apparent that there are important differences between these tumors and their more common intracranial counterparts...

Pediatric intramedullary spinal cord astrocytomas are rare, and the majority are low grade, typically carrying a low risk of mortality, but a high risk of morbidity. Quality of life is, therefore, an important consideration in treating concomitant progressive kyphoscoliosis. Compared with fusion-based spinal stabilization, fusionless techniques may limit some complications related to early instrumentation of the developing spine. Another consideration is the timing of radiation therapy relative to both spinal maturity and spinal instrumentation...

The glioneuronal tumor with neuropil-islands is considered a rare variant of an astrocytoma. Congenital cases of glioneuronal tumor with neuropil-islands, which typically arise in adults, have not been reported to our knowledge. We report an autopsy case of an in-utero demise of a 38-week-gestation female fetus in a 29-year-old female. At autopsy, a previously detected supratentorial tectal mass (by fetal MRI) was identified. Histology showed a biphasic neoplasm marked by island of gray matter-like parenchyma rimmed by mature-appearing neuronal cells intermixed with variably cellular areas resembling a low grade astrocytoma...

Genetic alterations in the cells of intradural spinal tumors can have a significant impact on the treatment options, counseling, and prognosis for patients. Although surgery is the primary therapy for most intradural tumors, radiochemothera-peutic modalities and targeted interventions play an ever-evolving role in treating aggressive cancers and in addressing cancer recurrence in long-term survivors. Recent studies have helped delineate specific genetic and molecular differences between intradural spinal tumors and their intracranial counterparts and have also identified significant variation in therapeutic effects on these tumors...

OBJECT Although the usefulness of PET for brain lesions has been established, few reports have examined the use of PET for spinal intramedullary lesions. This study investigated the diagnostic utility of PET/CT for spinal intramedullary lesions. METHODS l-[methyl-(11)C]-methionine (MET)- or [(18)F]-fluorodeoxyglucose (FDG)-PET/CT was performed in 26 patients with spinal intramedullary lesions. The region of interest (ROI) within the spinal cord parenchyma was placed manually in the axial plane. Maximum pixel counts in the ROIs were normalized to the maximum standardized uptake value (SUVmax) using subject body weight...

Spinal intradural tumors, especially those extending along the entire length of the spinal cord, termed as 'holocord' tumors are uncommon. Most of these are gliomas, with astrocytomas (low grade) predominating in children and ependymomas in adults. Other histologies, though reported, are even rarer. Management is debatable, with both surgery and radiotherapy of such extensive tumors posing challenges. We describe a case of a 14-year-old girl with holocord astrocytoma extending from cervicomedullary junction till lumbar spine, who recovered full neurological function following radical irradiation of entire spine followed by temozolomide-based chemotherapy...

Encephalocraniocutaneous lipomatosis (ECCL) is a rare congenital syndrome with an unknown etiology. Since 1970, around 60 cases have been reported in English literature. ECCL is usually classified by cutaneous lesions and non-progressive intracranial or spinal lipomas; however three cases of ECCL associated with low grade glioma (LGG) have been described. We report on the fourth case of LGG in a patient with ECCL; a grade II pilocytic astrocytoma with pilomyxoid features in a 3-month-old male, the youngest in literature...

Neurofibromatosis von Recklinghausen type 1 (NF1) is a multisystem, autosomal dominant hereditary neurocutaneous disease characterized by skin, central and peripheral nervous system , eyes , bone, endocrine, gastrointestinal and blood vessel wall involvement. It has an estimated frequency of 1 in 3000. Neurofibromatosis type 1 is caused by mutations in the large NF1 gene located on chromosome 17q11.2, encoding the cytoplasmic protein neurofibromin. It is expressed in multiple cell types but is highly expressed in Schwann cells, oligodendrocytes, neurons, astrocytes and leukocytes...

OBJECT: Operations on tumors of the posteromedial temporal (PMT) region, that is, on those arising from the posterior parahippocampal, fusiform, and lingual gyri, are challenging to perform because of the deep-seated location of these tumors between critical cisternal neurovascular structures and the adjacent temporal and occipital cortexes. Traditional surgical approaches require temporal or occipital transgression, retraction, or venous sacrifice. These approaches may result in unintended complications that should be avoided...
