[Spinal cord compression by primary epidural non-Hodgkin lymphoma]

A 63-year-old man was admitted because of sudden paraparesis. Myelography revealed a complete block at the level of T-3. The spinal epidural tumor was histologically diagnosed as malignant lymphoma, diffuse large cell type and immunohistochemically B-cell type. A thorough work-up for metastasis including MRI was negative. He was postoperatively treated with combination chemotherapies (VEPA), followed by irradiation to the region. The residual tumor disappeared on chest-CT and the patient's neurological status rapidly improved. He is still in remission for 18 months and has full performance status. This case is a very rare lymphoma originated from spinal-epidural space.
