CLINICAL CASE: We report on a 7-year-old female with spinal pilocytic astrocytoma complicated by pseudoprogression 1 month after completion of radiation therapy. Although she was initially treated with high-dose steroids, her clinical symptoms did not completely resolve, and magnetic resonance imaging (MRI) revealed extension of the lesions into the medulla oblongata. Treatment with bevacizumab was commenced, followed by rapid resolution of the clinical symptoms and improvements in the MRI findings...

BACKGROUND: Clips implanted during intracranial neurosurgical procedures sometimes migrate intradurally with rare cases of spinal migration. The appearance of radicular symptoms of topography concordant with the position of the foreign body leads to discussion about the optimal therapeutic strategy. CASE DESCRIPTION: We report the case of a 52-year-old woman suffering from L5 radicular pain resistant to medical treatment in the presence of L4L5 lumbar stenosis and a neurosurgical clip migrated to the L5S1 level...

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...

OBJECTIVE: A spinal cord subependymoma is an uncommon, indolent, benign spinal cord tumor. It is radiologically similar to a spinal cord ependymoma, but surgical findings and outcomes differ. Gross total resection of the tumor is not always feasible. The present study was done to determine the clinical, radiological and pathological characteristics of spinal cord subependymomas. METHODS: We retrospectively reviewed the medical records of ten spinal cord subependymoma patients (M : F=4 : 6; median 38 years; range, 21-77) from four institutions...

A previously healthy male presented at age 5 years with recurrent abdominal pain that occurred diffusely. The pain was severe enough to cause episodic screaming, especially at night with spontaneous resolution. The patient was initially treated for constipation but when motor symptoms began to develop, imaging revealed the cause of his pain to be a spinal cord mass. The tumor was treated with steroids, and biopsy confirmed a grade II spinal cord astrocytoma. We describe this unusual presentation of a pediatric spinal cord astrocytoma and review the literature...

Among spinal tumors that occur intradurally, meningiomas, nerve sheath tumors, ependymomas, and astrocytomas are the most common. While a spinal MRI is the state of the art to diagnose intradural spinal tumors, in some cases CT scans, angiography, CSF analyses, and neurophysiological examination can be valuable. The management of these lesions depends not only on the histopathological diagnosis but also on the clinical presentation and the anatomical location, allowing either radical resection as with most extramedullary lesions or less invasive strategies as with intramedullary lesions...

BACKGROUND: Exophytic growth (EG), wherein the tumor mass grows beyond the neuraxial boundary formed by pia mater, remains a rare pattern of glioma growth. It has been described in gliomas at several locations like the brainstem, cerebellum, suprasellar area, spinal cord, and insula. However, EG in hemispheric grade 2 astrocytomas, particularly affecting the convexity subarachnoid space, as against the more spacious basal subarachnoid space, is exceedingly rare. To the best of our knowledge, there is only 1 such case reported in the English literature...

Bette K Kleinschmidt-DeMasters, Jean M Mulcahy Levy
BACKGROUND: H3 K27M mutation was originally described in pediatric diffuse intrinsic pontine gliomas (DIPGs), but has been recently recognized to occur also in adult midline diffuse gliomas, as well as midline tumors with other morphologies, including gangliogliomas (GGs), anaplastic GGs, pilocytic astrocytomas (PAs), and posterior fossa ependymomas. In a few patients with H3 K27M;mutant tumors with these alternate morphologies, longer survival has been reported, making grading difficult for the neuropathologist...

OBJECTIVE: Spinal cord astrocytoma with intracranial dissemination carries a poor prognosis. The mechanisms leading to dissemination remain to be elucidated. A stem cell marker, CD133, was reported to predict recurrence patterns in intracranial glioblastoma. We evaluated the significance of CD133 as a putative prognostic biomarker to predict intracranial dissemination in spinal cord astrocytoma. METHODS: This study included 14 consecutive patients with primary spinal cord astrocytoma treated from 1998 to 2014...

OBJECTIVE Primarily metastatic juvenile pilocytic astrocytoma (JPA) is rare, likely representing 2%-3% of all cases of JPA. Due to the rarity of primarily metastatic JPA, there is currently no standard treatment paradigm and the long-term outcomes are not fully known. The goal of this case series was to add to the current understanding of this disease process. METHODS The authors searched a comprehensive database of pediatric patients with brain and spinal cord tumors treated at Lucile Packard Children's Hospital from 1997 to 2016 and identified 5 patients with primarily metastatic JPA...

BACKGROUND: Intramedullary spinal cord tumors (IMSCTs) are rare, heterogenous lesions that are usually enhanced on preoperative magnetic resonance imaging (MRI) because of a damaged blood-brain barrier. Sodium fluorescein is a dye that accumulates in areas of the central nervous system with a damaged BBB. Given the pattern of MRI contrast enhancement of the majority of IMSCTs, the use of this fluorescent tracer could improve tumor visualization and quality of resection. In this article, we present the first experience with the application of fluorescein-guided technique for surgical removal of IMSCTs...

INTRODUCTION: Grade II intramedullary astrocytomas are rare tumors. Despite a well-defined role of adjuvant temozolomide chemotherapy for brain gliomas, the contribution of this therapy for intramedullary gliomas is not yet clearly defined. METHOD: We retrospectively analyzed the data of 5 adult patients treated with temozolomide between 2008 and 2015 for a grade II intramedullary astrocytoma with progression after surgery. RESULTS: Five patients from 19 to 70 years of age (median, 37years) underwent a second surgery for the progression of a grade II intramedullary astrocytoma (median progression-free survival 26months [8-90])...

INTRODUCTION: Spinal cord tumors in children (SCTC) are rare with a frequent diagnostic delay. Its management is multidisciplinary and challenging due to functional implications. The position of surgery is now better established but the role and timing of chemotherapy (CT) and radiotherapy (RT) still remains under debate. Adverse effects of treatments are important to be taken into account, in the follow-up of these children. The aim of this paper was to present a series of 21 cases of SCTC treated at the same institution, to briefly present clinical features, treatments and outcome, with a special focus on spinal deformities in children with this condition...

Intramedullary spinal cord tumors (IMSCTs) are relatively infrequent lesions with ependymomas and astrocytomas representing the most common types. Microsurgical resection is established as the treatment of choice for these challenging lesions. We reviewed the surgical outcome of 29 cases operated for IMSCTs by the same surgeon between 2009 and 2015. The median follow-up period was 31 months, and all patients were followed up at least for 1 year. Among these 29 cases, 5 patients were previously operated for partial resection elsewhere...
