Myxopapillary ependymoma


Oblong isointense T1 hyperintense T2 avidly enhancing mass in the caudal spinal canal which is intradural.


The most common type of spinal cord tumor in children is astrocytoma followed by ependymoma. The myxopapillary subtype is only 8-12% of the ependymomas in children.

Typical clinical presentation is chronic back pain, often with a delay in diagnosis.

The myxopapillary ependymoma occurs almost exclusively in the conus, cauda equina or filum terminale. A well circumscribed avidly enhancing mass with associated hemorrhage is typical. The mass is usually isointense to cord on T1 and hyperintense on T2.

Differential includes mets, neurogenic tumor or acquired epidermoid.
