Multiple myeloma and other plasma cell disorders are characterized by production of a large number of plasma cells in the bone marrow. On the other hand, plasmacytoma results from proliferation of abnormal plasma cells in the soft tissue or skeletal system. Neurological complications are frequently observed in these diseases. The most commonly known complications among those complications are spine fractures, spinal cord compressions, and peripheral neuropathies. Although neurological involvements are common in plasmacytomas, extramedullary spinal epidural localizations have been reported very rarely. In this case report, we aimed to present a plasmacytoma case that presented with acute onset of upper extremity monoparesis. A 40-year-old woman was admitted to our clinic with complaints of sudden weakness and numbness in her left arm following neck and left arm pain. Emergency cervical magnetic resonance imaging (MRI) revealed an epidural mass and the patient underwent emergency surgery. The patient showed improvement post-operatively and the pathology was reported as plasmacytoma. Following hematology consultation, systemic chemotherapy was initiated and radiotherapy was planned after wound healing.
