Question:

Reportability--Brain and CNS: Are schwannomas of the spinal cord reportable when they are intradural? See Discussion.

Discussion:

The CNS guidelines basically indicate that schwannomas must all come from peripheral nerves and thus are not reportable when they are on the spinal cord. However, the COC Inquiry 18174 & 18068 states that schwannomas occasionally will develop inside the dura (intradural) on the spinal cord and would be reportable.

Answer:

According to an expert consultant, schwannomas must be derived from Schwann cells which are not a part of the CNS. All schwannomas come from peripheral nerves. Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable.
