Solitary thoracic intradural extramedullary plasmacytoma.
The bodies of the vertebrae are common locations for plasma cell diseases such as multiple myeloma and solitary plasmacytoma. Secondary invasion of the epidural space is infrequent but can cause neurological symptoms. Spinal cord compression due to pure intradural plasma cell infiltration is very rare. The authors report a 25-year-old woman who developed a progressive difficulty in walking due to a solitary spinal dural plasmacytoma. This is the first reported example in the English language literature of a purely intradural spinal plasmacytoma in a patient without other myelomatous lesions. An entirely intradural solitary plasmacytoma has a relatively better prognosis.
