Amyotrophic lateral sclerosis diagnosed after lumbar epidural block for treating low back pain: Two cases report

ABSTRACT

Lumbar epidural block is one of effective methods for treating low back pain with or without radiculopathy. However, neurologic complications can occur after epidural block due to several causes such as direct nerve injury or epidural hematoma. It is important to determine whether the neurologic complication is related to the procedure or is due to the underlying neurologic disease. We report two cases of patients who complained of weakness in their lower extremities after receiving a lumbar epidural block; they were ultimately diagnosed with amyotrophic lateral sclerosis.
