Extramedullary plasmacytoma of the tibial nerve: illustrative case
This case highlights a rare occurrence of peripheral nerve invasion by an EMP with the first documented involvement of the tibial nerve. This report suggests that EMPs should be considered in the differential diagnosis of PNSTs, particularly in MM patients. The present case underscores the need for intraoperative biopsies in PNST resection, as imaging features alone may not be fully diagnostic. https://thejns.org/doi/10.3171/CASE25104.
