[The clinical aspects of neuroblastomas and ganglioneuromas with intraspinal involvement]

Two cases of dumbbell tumours (one ganglioneuroma, one neuroblastoma) are presented. The incidence and symptomatology are shown. It is mandatory to examine the intraspinal situation in all paraspinal tumours by CT-metrizamide myelography. We recommend to do the laminectomy and the removal of paraspinal mass in a single operation.
