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.
