Abstract
Neoplasms in the region of filum terminale are not uncommon. Myxopapillary ependymoma
is the commonest tumor at this location. The differentials reported for this entity
are nerve sheath tumor, meningioma, paraganglioma, intradural metastases, lymphoma,
other varieties of ependymoma, subependymoma, astrocytoma, ganglioglioma, hemangioblastoma,
and primitive neuroectodermal tumor (PNET). PNET may very rarely present as an intradural thoracolumbar mass. We present
pre- and post-therapy magnetic resonance imaging (MRI) features of a patient with
proven primary spinal primitive neuroectodermal tumor (PSPNET) of peripheral subtype.
