Case Discussion
This case demonstrates a pathology-proven thoracic cord low-grade astrocytoma.
Spinal astrocytomas are the second most common spinal cord tumor. They represent 40% of intramedullary tumors and account for 60% of pediatric intramedullary tumors, making them the most common spinal cord tumor in children 1,2.
