Question:

Reportability--Brain and CNS: Is an "intradural extramedullary schwannoma (neurilemoma)" of the spine reportable? See Discussion.

Discussion:

Example: Pt underwent laminectomy and excision of intradural extramedullary tumor.

Is there a default decision for tumors described as intradural extramedullary tumors, NOS?

Answer:

For cases diagnosed 2011 and later:

A spinal "intradural extramedullary schwannoma (neurilemoma)" is reportable. This schwannoma originated in the spinal nerve root, C720.

History:

For cases diagnosed 2004-2010:

This case is not reportable. According to an expert consultant, schwannomas must be derived from Schwann cells which are not a part of the CNS, so they must all come from peripheral nerves, thus they all come from nerve roots and as such are NOT REPORTABLE.
