[A case of extramedullary multiple myeloma manifested as an epidural mass in the cervical spinal cord].
A 76-year-old man who rapidly developed quadriparesis was admitted to our hospital. MRI showed an epidural mass extending from C4 to C6, displacing the spinal cord anteriorly. It showed isointensity on the T1-weighted imagines, hyperintensity on the T2-weighted images, and diffuse hyperintensity with gadolinium enhancement. Plain radiographs, CT and MRI showed no evidence of bone involvement. Serum immunoelectrophoresis disclosed M-components of IgA and lambda light chains. This is the first report that an epidural myeloma in the cervical spinal cord caused compression of the cord without evidence of bone involvement.
