Solitary plasmacytoma: An unusual dural-based lesion - A case report.

Abstract

Solitary intradural plasmacytomas are extremely rare. We present a case of a patient with headache and diagnosis of meningiomatosis. Onset symptoms were abrupt neurological deterioration and paraparesis. The patient underwent surgery by craniotomy and tumor resection, with final pathological findings of solitary extramedullary plasmacytoma without evidence of multiple myeloma. Of note is the great similarity of this infrequent pathology with meningiomas and the need to differentiate it from the dural involvement of multiple myeloma. Treatment always includes tumor resection surgery and postoperative radiotherapy.
