Correct answer:

1. What is the diagnosis?

Myxopapillary Ependymoma

2. Is this location typical for this tumor?

 Yup

3. Compared to the normal ependymomas, these do what?

Tend to bleed more.

Myxopapillary Ependymoma

The most common primary cord tumor of the lower spinal cord.


KEY FEATURES

This form is almost exclusively seen in die conus and film (95%)

- More than 50% of all tumors of the film terminal and conus medullaries are myxopapillary ependymomas.

- They have a tendency to bleed, even more so than the intramedullary type

- They tend to occur in the 40s-50s.

- They can usually be excised completely, but if they extend into the subarachnoid space and/or surround the roots of the cauda equina then they are a huge pain in the ass to get rid of.
