title: Epidural hematoma after spinal anesthesia in a patient with undiagnosed epidural lymphoma.
abstract: The incidence of hemorrhagic complications after neuroaxial anesthesia is very infrequent. We report a case of a woman developing epidural bleeding 3 wk after performing an uneventful spinal anesthesia at the lumbar level L3-4 for removal of a wire loop in her left knee. No hemostasis altering medication had been taken before and after spinal puncture. The hematoma presenting at the lumbar level L2-3 had to be removed via laminectomy. Pathological examination of the hematoma revealed a highly vascularized centroblastic non-Hodgkin's lymphoma that was not diagnosed before surgery. The patient did not develop any neurological deficits.
  
  
  CONCLUSIONS
  We report a case of a women developing epidural bleeding 3 wk after performing an uneventful spinal anesthesia for removal of a wire loop in her left knee. Pathological examination of the neurosurgically removed hematoma revealed a highly vascularized epidural centroblastic non-Hodgkin lymphoma.
