giant cell ependymoma of the filum terminale: a case report
Authors
abstract
ependymomas accounts for about 2%–6% of cns and 60%–70% of spinal cord tumors. several histological patterns of these neoplasms are well known, but little attention has been devoted to a variant composed of giant cells. in spite of apparently “worrisome” histology, giant cell ependymoma seems to be a neoplasm with a relatively good prognosis. this report presents a case of giant cell ependymoma of the filum terminale in a 24-year-old woman and highlights the morphological diagnostic criteria for this rare tumor.

BACKGROUND Giant cell ependymoma of the filum terminale is a rare variant, generally manifested as a well-circunscribed intradural mass with an indolent biological behavior. CASE PRESENTATION We describe the case of a 48-year-old Mexican female who non-relevant past medical history, that developed a GCE of the filum terminale. Magnetic resonance imaging and computed tomography revealed the pr...

full textExtramedullary Myxopapillary Ependymoma of the Filum Terminale Associated With Syringomyelia: A Case Report
Aim: Ependymomas compose the majority of all intradural intramedullary spinal lesions. Filum terminale lesions are rarely associated with syringomyelia. Here we describe a case of extramedullary myxopapillary ependymoma associated with extensive syringomyelia located in the filum terminale. Material and Methods: A 34-year-old man admitted to our clinic with complaints of bilateral leg weakness,...
