title: An extramedullary plasmacytoma originating from the thoracic spinal cord: magnetic resonance imaging findings. Case report.
abstract: Extramedullary plasmacytoma (EMP) is a rare tumor. The authors report a case of an EMP originating in the thoracic spinal cord. To their knowledge this is the first report in which an EMP originating in this location is described. Isointense and hyperintense signals were seen on T1-weighted and T2-weighted magnetic resonance images, respectively, with marked irregular contrast enhancement and extensive edema. No evidence of bone marrow involvement or multiple myeloma was noted. The histological findings were compatible with an EMP.
