title: [Dumbbell-shaped nerve-tissue tumors of the posterior mediastinum. Apropos of 5 cases].
abstract: The authors present 5 cases of dumbbell neurogenic tumors with intraspinal extension. There were 4 neurilemmomas in four adults and 1 ganglioneuroma in one child. These tumors were benign. Neurological signs were observed in two cases. Widening of the intervertebral foramen at the level of the tumor is a very suggestive sign of dumbbell tumor confirmed by CT-Scan or MRI. Precise morphologic features must be assessed before embarking on the operation. The procedures used were: thoracotomy only in two cases, laminectomy then thoracotomy because of neurological signs in two cases, thoracotomy then laminectomy to fully remove tumor remnants in one case. No major morbidity was noted. The neurological symptoms resolved in two cases. A combined two-team approach with thoracic and neurosurgeons working together has not been used so far, but this possibility is probably the best choice for the future.
