Mild gait abnormality and leg discomfort in a child secondary to extradural ganglioneuroma.

Ganglioneuromas are benign and slow-growing tumors that most commonly originate from the sympathetic trunk. Ganglioneuromas often decrease in size and rarely require reoperation. Changes in gait or the onset of limb pain without a discernible local cause are indications for investigation of patients for possible intraspinal pathology. We report the case of a 5-year-old boy who presented with seemingly static symptoms, while the slow-growing tumor had enveloped nerve roots and caused bone destruction of the vertebrae.
