ependymoma/edema

Cortical ependymomas are uncommon lesions. We report a cortical ependymoma displaying an unusual imaging pattern. The lesion demonstrated a T1 hyperintense rim and limited perilesional edema but lacked contrast enhancement. T1 hyperintense rim and stalk-like ventricular extension of FLAIR

BACKGROUND The ventriculoperitoneal shunt remains, despite recent advances, the mainstay of treatment for hydrocephalus. Although it is used as a routine practice, and besides its recorded and documented safety, it often malfunctions due to a variety of reasons, most commonly referred to as

The main aim of this research was to demonstrate that the cortical and subcortical grey matter hypometabolism as revealed by fluorine-18 fluorodesoxyglucose-positron emission tomography ((18)F-FDG-PET) imaging in brain tumors is related to associated edema as demonstrated by magnetic resonance

OBJECTIVE The aim of this study was to investigate whether the tumor parameters of spinal intramedullary ependymomas are significant predictors of clinical presentation and postsurgical outcome. METHODS The study involved 21 cases of intramedullary ependymoma that were operated on between 1988 and

Tanycytic ependymoma is the rarest variant of ependymoma and occurs primarily in the spinal cord. Intracranial cases are even rarer. Only 9 ventricular and 5 subcortical tanycytic ependymoma have been reported in the literature. Amongst the 9 ventricular cases, only one tumor arose from the third

Background: Several previous reports of anaplastic ependymomas have described their imaging features, and most of these studies were case reports. However, no studies have compared the magnetic resonance imaging (MRI) features between the infratentorial and supratentorial anaplastic

Typical clinical characteristics, neuroradiologic findings, and initial neuroradiologic studies were reviewed for 40 patients <3 years of age with intracranial ependymomas, who were treated in the Pediatric Oncology Group (prolonged postoperative chemotherapy and delayed radiation for children <3

Introduction: Pregnancy-related spinal tumors (PRSTs) are unusual tumors that present during pregnancy or within a year after delivery. We describe a fatal holocord recurrence of a spinal ependymoma, which, to the best of our knowledge,

In order to provide a detailed description of the MR appearance of intracranial ependymoma, the MR examinations of 12 patients (10 with ependymomas and two with subependymomas) were reviewed and correlated with operative and pathologic reports. Three of 10 ependymomas were intraventricular, two were

A 15-year-old boy presented with an anaplastic supratentorial ependymoma causing massive intratumoral calcification, without contributory medical and family history, and manifesting as persistent headache for 2 months. Physical examination found no neurological deficit except for visual defect in

INTRODUCTION AND IMPORTANCE: Spinal ependymomas are slow-growing lesions that comprise the majority of primary spinal cord neoplasms. When surgery is indicated, the extent of tumor removal is most prognostic for long-term survival. Unusual histological subtypes can make intraoperative diagnosis

OBJECTIVE People with neurofibromatosis Type 2 (NF2) have a genetic predisposition to nervous system tumors. NF2-associated schwannomas stabilize or decrease in size in over half of the patients while they are receiving bevacizumab. NF2 patients treated with bevacizumab for rapidly growing

Supratentorial cortical ependymoma (CE), a rare type of ependymoma, is located in the superficial cortex. We reported 11 patients (six female and five male) with CE. The age of the patients ranged from 2 to 63 years old with a median age of 47 years at the time of diagnosis. On MRI, enhancement was
