INTRODUCTION: Pilomyxoid astrocytoma (PMA) is a rare and more aggressive variant of pilocytic astrocytoma, which usually affects young children and is most often located in the hypothalamic/chiasmatic region. The association of PMA with underlying genetic disorders is not well known. METHODS: We identified a 23-year-old woman with a PMA of the spinal cord who was simultaneously diagnosed with neurofibromatosis type 1. Diagnosis of neurofibromatosis type 1 was made clinically and confirmed with genetic testing that revealed a heterozygous one-amino-acid deletion (c...

Rosette-forming glioneuronal tumor (RGNT) is a recently recognized and rarely encountered tumor occurring in the fourth ventricle. Histologically, it is composed by two distinct features: a glial component, resembling pilocytic astrocytoma, and a neurocytic component forming neurocytic rosettes and/or perivascular rosettes. The authors describe two extremely rare cases of RGNT arising from the spinal cord, which were misdiagnosed as ependymoma and astrocytoma preoperatively. Symptoms included dissociated sensory disturbance, episodic pain and fatigue, as well as motor disturbance, had been presented for two years and two months, respectively...

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 Diffuse astrocytomas (DAs) have a high recurrence rate due to diffuse infiltration into the brain and spinal cord. Micro RNAs (miRNAs) are small noncoding RNAs that regulate gene expression by binding to complementary sequences of target messenger RNA (mRNA). It has been reported that miRNA-22 (miR-22) is involved in the invasion of some cancer cell lines. The aim of this study was to identify the biological effects of miR-22 in regard to the invasion of human DAs. METHODS The authors evaluated whether the level of miR-22 is elevated in human spinal DAs by using miRNA chips...

OBJECT: Desmoplastic infantile gangliogliomas (DIGs) and desmoplastic infantile astrocytomas (DIAs) are tumors typical of the infantile age. A large size, with a mixed solid and cystic component, clinical presentation with progressing signs of increased intracranial pressure, a prominent benign desmoplastic structure at histological examination, and a favorable clinical course in the majority of cases are the prominent features of these tumors. The objective of the present paper was to review the pertinent literature on the topic together with our personal experience, with the aim of an updated review of the subject...

Neoplasia of the spinal cord, including both primary and metastatic tumors, is relatively rare, representing 4%-10% of all central nervous system tumors, and can present a diagnostic challenge to the radiologist. More than 90% of primary spinal cord neoplasms are derived from the glial cell lineage, including the 2 most common tumors ependymoma and astrocytoma. However, less common spinal cord tumors, including metastatic disease, as well as nonneoplastic and paraneoplastic processes should be considered in the diagnosis of intramedullary spinal cord lesions...

INTRODUCTION: Intramedullary ependymomas are classically described as tumors developing in the center of the spinal cord, whereas intramedullary astrocytomas are more dispersed. This description only remains approximate. The aim of this study was to establish a lateralization index (LI), which is based on radiological measurements and may help in differentiating the two tumors. MATERIAL AND METHODS: Retrospective analysis based on the analysis of MRI of patients operated on for intramedullary astrocytoma or ependymoma in the Neurosurgical Department of Bicêtre Hospital...

BACKGROUND: Pilocytic astrocytoma (PA) is a benign neoplasm that typically occurs in the brain within the pediatric and adolescent age groups and is uncommon in adults. It rarely occurs within the ventricles and the overall prognosis is favourable. A pilocytic astrocytoma of the brain with spinal metastasis at presentation has never been reported in an adult. CASE DESCRIPTION: We report a case of a 47-year-old male presenting with sudden onset frontal headache associated with nausea and lethargy...

Recently, great advances have been made in the surgical treatment of intramedullary spinal cord tumors (IMSCTs). Many articles have been published; but looking at the literature of the last 5 years, there are only descriptive reviews and no works in which a literature statistical analysis was performed. Here, we analyzed the literature to identify potential prognosticators of good functional outcome in IMSCT patients. To level out the selected studies, we stratified patients' neurological status as independent (ambulation possible without caregiver assistance) or disabled (cannot ambulate or can only ambulate with caregiver assistance)...

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...

Intradural tumors are relatively rare neoplasms; however, when unrecognized in a timely manner, they can result in serious deficits and disability. These tumors lack obvious clinical symptoms until compression of the cord or neurologic deficits occur. The most common intramedullary lesions are ependymomas, astrocytomas, and hemangioblastomas. Meningiomas and nerve sheath tumors (schwannomas and neurofibromas) comprise most intradural-extramedullary tumors. Less common tumors are hemangiopericytoma, paraganglioma, melanocytoma, melanoma, metastases, and lymphoma...

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...

The adult rodent spinal cord presents an inhibitory environment for donor cell survival, impeding efficiency for xenograft-based modeling of gliomas. We postulated that mild thermal precondition may influence the fate of the implanted tumor cells. To test this hypothesis, high grade human astrocytoma G55 and U87 cells were cultured under 37°C and 38.5°C, to mimic regular experimental or core body temperature of rodents, respectively. In vitro, 38.5°C-conditioned cells, relative to 37°C, grew slightly faster...
