| ABSTRACT |
|
Spinal cord compression associated with plasma cell neoplasm is observed always in the patients suffering from the multiple myeloma or solitary plasmacytoma that occur in the marrow of the spine. Authors report a rare case of extramedullary plasmacytoma forming a mass in the epidural space of the thoracic spine. In 70 year old woman with paraplegia, MRI of the thoracic spine indicated a presence of epidural mass at the 2nd to 8th thoracic vertebrae. There was no abnormal bony changes in the spine on plain X-ray and MRI. Total removal of the epidural mass was performed by posterior approach. Histopathologic examination including immunohistochemical stain showed the plasma cell neoplasm producing IgM and kappa light chain. Cancer workup after operation including bone marrow study and whole body simple radiologic studies supported the diagnosis of extramedullary plasmacytoma. |
