Dumbbell ganglioneuroma of the lumbar spine associated with a herniated intervertebral disc: case report.

Paraspinal ganglioneuromas with extension into the spinal extradural space are rare tumors. Their management usually requires cooperation with surgeons of other specialties. The authors describe a case of a dumbbell ganglioneuroma arising from the lumbar sympathetic ganglia in a patient presenting with a herniated lumbar disc. The clinical features, radiographic analysis, and surgical approach to these tumors are briefly discussed.
