title: Motor Neuron Diseases Accompanying Spinal Stenosis: A Case Study.
abstract: A 75-year-old man, who was healthy, visited the hospital because of shooting pain and numbness in both lower limbs (right > left). The patient had an L4/5 moderate right foraminal stenosis and right subarticular disc protrusion and received a lumbar epidural block. The patient experienced severe weakness in the right lower limb after 2 days. Lumbar and cervical magnetic resonance images were taken and electromyography and a nerve conduction study were performed to arrive at the diagnosis of a motor neuron disease. The patient expired 4 months later with respiratory failure due to motor neuron disease. This case suggests that any abnormal neurological symptoms that occur after an epidural block should be examined thoroughly via testing and consultations to identify the cause of the symptoms.
