Introduction: Hydrocephaly is a common complication of intra ventricular brain tumors. The aim of this study was to determine, demographic and clinical features and type of hydrocephaly before and after surgical interventions in patients with intra ventricular brain tumor surgery. Material and methods: In a cross-sectional study, 100 patients with intra ventricular brain tumors who were candid...

purpose: to report a case of unilateral severe visual loss and bilateral optic disc cupping secondary to brain metastasis of bronchogenic carcinoma patient and findings: a 48 year-old woman presented with severe visual loss of left eye without redness or pain or any systemic findings .clinical findings included decreased visual acuity of left eye to 4 m cf and (+3) positive marcus-gunn reflex ....

BACKGROUND Primitive brain tumors are the leading cause of cancer-related death in children. Tumor cells with stem-like properties (TSCs), thought to account for tumorigenesis and therapeutic resistance, have been isolated from high-grade gliomas in adults. Whether TSCs are a common component of pediatric brain tumors and are of clinical relevance remains to be determined. METHODOLOGY/PRINCIP...

Background: In this study, we examined the epidemiologic characteristics of childhood brain tumors in patients referred to MAHAK Pediatric Cancer Treatment and Research Center (one of the main national referral centers for childhood malignancies in Iran) for treatment. Materials and Methods: This cohort (simple sampling) study consisted of 198 children less than 15 year old with CNS tumor ref...

BACKGROUND/AIM While neuron-glia 2 (NG2) is well-characterized in the developing brain and in adult high-grade gliomas, little is known about NG2 expression in paediatric brain tumors. Here, NG2 expression was examined in a range of paediatric brain tumors. MATERIALS AND METHODS A retrospective immunohistopathological analysis of 57 paediatric brain tumor biopsies of various tumor types was c...

to investigate the effects of the two-pore-domain potassium (k2p) channel task-3 in a syngeneic murine model for malignant glioma. malignant or high-grade glioma (who grade iii and iv) are the most common and most aggressive primary brain tumors in adults. despite aggressive multimodal therapy, the outcome of patients with malignant glioma remains poor. however, recent phase i and ii trials hav...

BACKGROUND Diffusion-weighted imaging (DWI) is a form of magnetic resonance imaging (MRI) based on measuring the random Brownian motion of water molecules within the biological tissues and is particularly useful in tumor characterization. OBJECTIVES The purpose of this study was to evaluate the diagnostic value of DW MRI and the apparent diffusion coefficient (ADC) for preoperative grading of...

BACKGROUND AND PURPOSE Pediatric brain tumors have diverse pathologic features, which poses diagnostic challenges. Although perfusion evaluation of adult tumors is well established, hemodynamic properties are not well characterized in children. Our goal was to apply arterial spin-labeling perfusion for various pathologic types of pediatric brain tumors and evaluate the role of arterial spin-lab...

Giant cell glioblastoma is an extremely rare variant of Glioblastoma (WHO grade IV) which is characterized by a predominance of bizarre, multinucleated giant cells. These tumors comprise of 0.8% of brain tumors and up to 5% of glioblastomas. In pediatric age group, these tumors are still uncommon with only around 53 published cases since 1952. Here, we report a case of a 12-year old female pat...
