The roentgenologic diagnosis and differentiation of mediastinal neurogenic tumors are possible on the chest roentgenogram as a rule. The soft tissue mass may be ill-defined and the tumor "ghost-like" in the case of primary neuroblastoma, but it is usually obvious in ganglioneuroma and metastatic disease. The presence of calcifications differentiates neurogenic tumors from other posterior mediastinal tumors of childhood. They are common in primary and rare in secondary disease. Rib erosions and displacement are striking in neuroblastoma (after a few months of age), more subtle in ganglioneuroma, and absent with secondary involvement. In 3 out of 7 posterior mediastinal neuroblastomas the diagnosis and treatment were delayed, as the adjacent rib changes were not appreciated for some time. "Dumbbell" shaped tumors are usually associated with vertebral changes and myelography is indicated even in the absence of neurologic deficit. Thoracic deformity and disability subsequent to laminectomy, radiation therapy, or both, are present in all survivors.

Thoracic dumbbell tumors are relatively uncommon neoplasms that arise from the neurogenic elements. Surgical resection can be challenging as the tumor involves both the spinal canal and thoracic cavity. Historically, thoracotomy and laminectomy were utilized for the resection of these tumors. Although single-stage removal of such tumors has been described recently, there is no prior description of a total minimally invasive single-stage resection of a thoracic dumbbell ganglioneuroma. The current report describes a completely minimally invasive surgical resection for such a tumor performed using the posterior minimally invasive tubular approach to resect the intraspinal component with ligation of the T2 nerve root in conjunction with robotic-assisted thoracoscopic resection of the extraforaminal, intrathoracic component of the tumor. This report illustrates the safety and utility of a completely minimally invasive endoscopic resection of a thoracic dumbbell tumor that can potentially obviate the morbidity associated with open surgical resections for such tumors.
