Myxopapillary ependymoma almost only occurs in conus medullaris, cauda equine and terminal filament, and myxopapillary ependymoma has distinctive morphology and immunohistochemical phenotype. The article will discuss two rare cases report of myxopapillary ependymoma. The two cases occur in lumbar spinal canal, tumor cells arrange in well-differentiated blood vessels or around the mesenchymal ax...

PURPOSE The outcome of recurrent ependymoma in children is dismal. Reirradiation has been proposed as an effective modality for ependymoma at relapse. However, the toxicity and outcome benefits of this approach have not been well established. METHODS AND MATERIALS We conducted a retrospective population-based study of all patients with recurrent ependymoma treated between 1986 and 2010 in our...

Background: Spinal cord tumors represent 2-4% of all CNS tumors. Ependymomas are the most frequent lesions spinal cord1. Gross total resection remains gold standard2. Method: We describe mini-invasive surgical technique using a fixed tubular retractor performed for an ependymoma filum terminale, along with its advantages and limits. Conclusion: This has shown to be safe effective terminale epen...

A 36-year-old man presented with trouble speaking and bilateral progressive hearing loss. MR imaging and histopathologic results revealed a posterior fossa melanotic ependymoma. Pial surfaces appeared hyperintense on T1-weighted images and hypointense on T2-weighted images. Histopathologic examination revealed that tumor cells and interstitial spaces had abundant melanin accumulation. There was...

Dr. Merchant provides a comprehensive overview of intracranial ependymoma in children. As he points out, most of the current information regarding childhood intracranial ependymoma has come from single-institution retrospective reviews. Of the prognostic indicators mentioned in the article, both young age and subtotal resection are widely accepted. Children less than 3 years old have a worse pr...

AIM Ependymal tumours are relatively uncommon primary neoplasms of the central nervous system. Histological criteria distinguishing ependymoma and anaplastic ependymoma are not clear-cut and other parameters are required to allow more precise prognostication in these tumours. We analysed the histological and immunohistochemical features of these tumours (Ki-67, cyclin D1, EGFR, hTERT, Olig2) an...

Anaplastic ependymoma is associated with a higher incidence of tumor recurrence and its prognosis still remains unsatisfactory. Consolidated therapy for ependymoma includes surgery followed by focal radiotherapy when resection is incomplete. In the case of relapse treatment, options are limited especially for patients who have already received radiotherapy. We sought to establish the feasibilit...

BACKGROUND AND PURPOSE Only a few reports on intramedullary tumors of the spinal cord using PET have been published. We report findings of PET by using [(18)F] fluorodeoxyglucose and [(11)C] methionine and discuss the usefulness of the findings in patients with intramedullary tumors of the spinal cord. MATERIALS AND METHODS PET/CT was performed in 9 patients with intramedullary tumors of the ...
