[An undiagnosed plasma cell myeloma. Complication after performing spinal anesthesia].

A male patient developed neurological deficits after an uneventful spinal anesthesia. After 2 months without any improvement an epidural hematoma was presumed. Magnet resonance imaging detected inflammatory tissue and destruction at lumbar levels L2/3. The inflammatory tissue had to be removed via laminectomy. Histology of the excised tissue revealed a plasma cell myeloma that was not diagnosed prior to spinal anesthesia 2 months previously.
