The ganglioneuroblastoma is a rare tumor originating from the sympathetic chain. Both cytologically and biologically it is intermediate between the highly malignant neuroblastoma and the benign gauglioneurinoma. The predilection site of neuroblastoma is adrenal medulla, but ganglioneuroblastoma and ganglioneurinoma are frequently located in the retroperitoneum and mediastinum. We have recently experienced the dumb-bell shaped ganglioneuroblastoma at L-2 and 3 level. A 2 year-old-girl was admitted to Seoul National University hospital on May-1975 with complaints of lumbar back pain and kyphosis for 6 months. She had normal motor and sphincter function. Neurological examination showed normal. Simple lumbar spine X-ray showed the widening of interpedicular distance and erosion of the pedicle at L-2 and L-3. On lateral view scalloping of posterior border of L-2 was found. Lumbar puncture and myelography were failed. Total laminectomy at L-2, L-3 was done. Dumb-bell shaped mass was seen half in the extradural intraspinal space and half in the extraspinal space with pedicle in the widened intervertebral foramen. The mass was adult thumb-tip sized, dark grayish tan color, nodular surfaced, and well encapsulated. The tissue diagnosis was ganglioneuroblastoma. Post-operatively urinary secretion of vanyl-mandelic acid level was normal limit.
