Overview
Pathophysiology
Gross Pathology
- Ganglioneuromas are solid, firm tumors that are typically white when seen with the naked eye
- Ganglioneuromas arise in the paravertebral sympathetic chains of the posterior mediastinum (41.5%) or retroperitoneum (37.5%)
- Less common sites include the adrenal gland (21%) and neck (8%)
- Paravertebral ganglioneuromas frequently extend through the neural foramina to involve the epidural space of the spinal canal
- Intradural extramedullary ganglioneuromas are extremely rare[1]
Microscopic Pathology
- Ganglioneuromas are derived from the primordial neural crest cells, which are undifferentiated cells of the sympathetic nervous system.
- Ganglioneuromas are fully differentiated neuronal tumors that do not contain immature elements.
- They are composed of ganglion cells, schwann cells and fibrous tissue.
